A New Autoguider

In 2014, the head of CBSAP, USA Mr Stephen Ramsden donated a premium 127mm APO refractor telescope (with other stuff) to me so that can help me with more outreach programs. This telescope has shown the Sun to tens of thousands of people all across the province of Punjab. They include people found in public parks, kids in schools, colleges and universities. I have also used this scope countless time to see the night sky objects and to image moon, sun, planets and many dso. 

I am using this refractor telescope on my previosuly owned Celestron CGEM DX mount. Always wanted to use more potential of this scope. So i recently bought an autoguider scope which will attach with the big APO and give me a 'hands free' experience of imaging deep sky objects. The make is Orion and its an 80mm refractor. Here are the images from the unboxing event!

Lahore Science Mela

Khwarizmi Science Society has taken such a giant leap forward in bringing public to the arena of pure scientific curiosity which you would have to see to believe it!

It will be held for two full days from 09:00am to 06:00pm, on 28-29 January, 2017 at Ali Auditorium, Lahore.

I, along with my good friends from Lahore Astronomical Society will be there with our many telescopes, astronomical cameras and more, for a massive outreach astronomy program for thousands of people, all day long.

Here is a wonderful introduction made by KSS and Dr Sabieh Anwar.

Solar Outreach, Gujranwala

I was invited to a Madrassa in Gujranwala during their short course on "Ilm e Tauqeet"  (time keeping). 

Had a wonderful time there.. Talked a lot about Science and Astronomy to the students and teachers of the Madrassa. They asked great questions and a lot of them!

Next we went to the roof where my Halpha Solar Telescope was placed. We saw the sun and Solar Prominence in the eyeiece of the scope.

Came back home with a very happy astro heart :-) 

Mouse in the Observatory

Yesterday i thought to get some Photometry data because the fog was not intense and the humidity was 70% in the evening. Little did i expect what was for me there in the observatory!

When i opened the Human Room, THIS is what i saw:

Two wires have been cut (marked with arrows, showing both ends) and some polystyrene sheet has been damaged. Immediately a picture of the mouse appeared in my mind.. this is bad!

I tried to find the mouse inside the room but it is filled with a million things. I knew he must be hiding now somewhere here and perhaps he is not even here right now but i had to do a thorough search.

Finally i found him.. the enemy was hiding deep in the back corner of the freezer. I tried to convince him logically that he cannot live on my planet and he should go back to his own but for some unknown reasons, he did not respond.

Then i had to do what an angry Samurai would do.. I threatened him with my martial arts skills. He got furious and suddenly jumped and started running everywhere. Believe me, when it moved, it moved faster than the speed of light (no disrespect to Einstein).

I tried to show him the outdoors respectfully but he was in no mood to move out. At one point, i lost him. Tried to locate him everywhere but in no vain. May be he has gone out of the room after all but i had to confirm it.

Suddenly i remembered that i have a Thermal Imaging Camera from Seek Thermal which can be attached to the iPhone. Immediately connected it and started scanning the room. It was not on the floor or behind the wires or tables.. perhaps the thermal camera cannot pick out his heat signature.

But then when i pointed the camera on the wall.. I saw this view:

Right is the normal view and left is what Thermal Camera is showing me. The devil was inside the wall!!! This is becoming so Tom and Jerry now!

I finally made so much noise and hits to the wall that he came out and after another 10 minutes or so of me being chasing him out, he finally decided to end my cardio and left with the grace of Splinter (yes, i was also a child once!)

New toy in Observatory

I always have survived with my mount for the last 12 years, without something that i thought is not needed.

Back in 2003. There were no GPS in mobile phones. I bought a Garmin GPS specially from USA to know my coordinates. It worked all fine!

Then Mobile phones introduced GPS and there was no need to have a separate GPS receiver. I have been using this whenever i want to locate the geo-position for any of my mount. It has been working fine!

But there is some project which need very accurate time registration in Photometry and Astrometry. I have been using internet atomic clocks to synchronize my computer clock so far. But i decided to get a proper dedicated GPS for my mount now.

It arrived today at the observatory and i have installed it in the mount tonight. It has a cable with it because GPS receiver works best when not in the vicinity of any metal which is what a mount if made of.

I turned on the mount, the Gemini 2 control indicated it has detected a GPS attached and has updated tit with the GPS data. Now there will be one less step in my setup for the imaging runs.

Changing Temperature's effect on focusing

When i connected the telescope and camera today with my computer, the TCF Focuser temperature readout showed the temperature of the telescope to be 18 C. I thought let's experiment on the temperature and defocusing simple relation.

I focused the telescope on a readout at 4,000, which is the position on the TCF auto focuser. Kept on imaging for a while and when the temperature went 2 degrees below at 17 C. I refocused again and got a number of 4,499.. so the focus has been shifted around 450 values.. this is a huge difference!

The following picture will illustrate it better.. Notice the pointed star in both images. The left shows the FWHM value of 3.45 at the temperature of 17 C, this is rather a blurry star now but it was at tight focus when i focused it at 19 C.

On the right is the same star at FWHM of 1.88 at 17 C but after refocusing.. this is much much better.

So with 2 degrees of temperature drop, the FWHM of the star increased from 1.88 to 3.45! This translates as a very accurately focused start to a poorly focused star. What i want to show is we need to constantly keep an eye on focusing. That is why the high end focusers come with the temperature compensation option.. I always keep my system at the temp compensation mode. This keeps on changing the focuser position by noticing the change in the temperature. TCF can detect a a change of a tenth of degree!

Oh and btw, for those who don't know know about it. FWHM is a widely used number to see how small a star is in any image. The lower number is always better. Web has a lot of sources about it.

Solar Outreach at Beaconhouse DHA

I went to Beaconhouse Phase 6 branch today and the students of grade 2 got to see the sun from Lunt Halpha Solar Telescope. They were very happy, rather stunned to see the sun in the eyepiece. I am sure many of them will become scientists or better Astronomers in the future!

Asteroid 468 Lina movie

Here is a 3 hours tracking of an asteroid which is having a prograde rotation around the sun right now.

Here is the combined image of all three hours of data. The trail is from this asteroid path it took in all this time. Sorry about the 'dust donuts'.. i did not apply flats to these images.

22 Kelliope Asteroid observation

On the night of 13 October 2016, i observed an asteroid 22 Kelliope from 02:01am to 03:24am in 700-900nm wavelength band. My CCD camera was at -20 Celcius. The focal length of my imaging system is now at 4390mm and the image scale is 0.94 arcseconds per pixel. 

Here is the path of this asteroid in stacked 114 images of 30 seconds of each exposure.

The line is the path which asteroid was on. You can tell that it was getting brighter on its way 'up'.

Here is the lightcurve of its 200nm Infrared band.

View fullsize

X axis is time in Julian Date and Y axis is Instrumental Magnitude scale.

You can see that when i started taking data, the asteroid was dimming and then it rose to almost half magnitude. This lightcurve shows the rotation of about one and a half hour period.

View fullsize

X axis is time in Julian Date and Y axis is Skyglow in ADU (analogue to digital units)

Interestingly, the sky glow was decreasing with time. This is perhaps because the moon was setting in the west and the city lights were switching off.. but i am not sure of the reason yet.

Blue Snow Ball NGC 7662

NGC 7662 used to be like our own Sun. After using all its nuclear fuel, it ended its life and spewed the elements inside it to its surrounding space.

Though it is bright, having a magnitude of around 8 (you can see the central part is over exposed ) it is however a small nebula, about 30 arcseconds in size. Here is an image from a website,

The area of this image is the size of the full moon. In the center of the image, the bright 'star' is this Nebula.. no detail can be seen at this magnification.

Luckily i have C14 and the above image is showing the complex details of the gases which were thrown out form the star in different times and in different angles. I was auto-guiding with both the mount and SBIG AO8 Adaptive Optics; guiding corrections were being applied few times a second. This is 

Of course whenever i image something, i look how Hubble Space Telescope saw it. This is how it is compared with my image. Hubble's image both optical (green) and Infrared (red) combined.

Lunar Eclipse from Lahore

Part of the Earth's shadaw grazed the lunar landscape yesterday night. Here is a single image from CBSAP 127mm APO Triplet and Canon 6D. I passed it through Photoshop to add some sharpenening though.

Lecture on 'Biking the Silk Road'

Kaiser Tufail has been an inspirational speaker at LAST for a couple of years now. His presentations are very informative and the way he explains everything makes so simple to understand it all.

Last night, he gave a review on his tour to China which he did on bicycle! yes Bicycle!! It was filled with some of many many images he captured on the way, which showed the culture and beauty of the land he was traversing.

There were many interesting events as well, like his camping in the desert and the tent got blown away by the severe sand storm and then there were some problems which were due to the language barrier but he somehow managed it.

Thank you Kaiser Sahib for this wonderful talk.. everyone was thrilled there!

Mars Mania 2016!

“Mars, closest in the past 11 years.”

On the 30th of May, 2016, some members of Lahore Astronomical Society gathered at Zeds Astronomical Observatory for a visual and photographic session to observe the planet Mars through the array of telescopes, lined up at the observatory's roof top. This event was arranged because of the 1-in-a-decade event that was to go down! The planet Mars was closest to Earth (77 million kilometers) that night and appeared brightest in the sky. It was also the time when it would appear quite big (in 'Mars-through-a-telescope' terms!) through our telescopes. The sky was exceptionally clear and we just couldn't miss such an event! And we didn't!
First one to show up was our Executive Member, Kaiser Tufail Sb. He brought his Celestron 6" SCT with him and set it up in a corner and began observation as soon as Mars was in sight! Meanwhile, there were 2 telescopes getting ready for Mars. First, Sameer Rashid Shami's Celestron 8SE SCT with SBIG ccd cameras, mounted inside the new observatory. Sameer spent a good couple of hours setting up the scope (focusing, attaching his DSLR instead of SBIG, refocusing and simply waiting for the temperature of his OTA to acclimatize with the outside atmosphere for minimal turbulence). Meanwhile, Umair Asim was busy setting up his Celestron C14 (the biggest telescope at the observatory). He had a long tube inserted in the OTA to help ventilate some of the outside air into the telescope, for rapid acclimatization. I, Roshaan Bukhari, joined the group of 3 and brought the observatory's 10" Dobsonian reflector that I had borrowed a few days earlier. I began setting it up as well. Tried to center it on Mars and Saturn to get a feel for the atmospheric conditions, which were pretty bad for Mars (since it was quite low on the horizon). We were later joined by Ahmed Mudassir Khan Sb with his 6" refractor and Celestron AVX mount. Unfortunately, his mount did not power up due to some technical fault in the power supply unit (which was fixed the next day!). Some moments later, Maroof Mian, Mian Mateen, Shoaib Usman Banday and Usman Maqsood Mirza joined in. Aamna Saleem joined us as well! 

Everyone busy with the equipment. Setting up for Mars. Mian Mateen is seen in the middle, trying his hand at afocal imaging of Mars with his mobile phone camera. 

Umair Asim soon announced that the Celestron C14 was available for visible eyepiece observation of Mars and Saturn! Visible observation from the giant telescope! Unbelievable is an understatement. I was fortunate to have seen Saturn with a 2.5x PowerMate and a 9mm eyepiece, along with Mian Mateen and Aamna Saleem. It was simply fantastic. The seeing conditions were such that the Cassini division would appear and disappear in a moment of milliseconds and one had to be patient if they wanted to see more details on the planet itself. The moments of clarity were astonishing. I and Mian Mateen tried our hand at afocal imaging of Saturn and Mars from the huge scope! The views, as magnified as they were, also magnified the atmospheric distortion. Our images looked promising but we knew we had to process them with a bit more technique and details would still be a little hard to bring out. We were, afterall, seeing the distant worlds at around 800x! We could easily see the rotation of Mars compared with our early observations (around 9pm) and our latest observations of the night (around 1 am). The planet and its surface features had indeed rotated out of and into view! Something so mundane and a 'back of the hand' fact suddenly appeared to be 10x more fascinating and amusing. There is indeed no alternative to a visual, eyepiece observation of the heavens!
Nonetheless, all our efforts were fruitful when the results came in the next day.
The Mars Mania 2016 was a success! Everyone enjoyed the views of the planet Mars. Here are some of the images of the red planet taken by members of Lahore Astronomical Society from their amateur equipment from before, during and after the Mars Mania event we had at the observatory.

Official Inauguration of Zeds 2.0

"On this date; the 6th day of April, the year 2016 A.D"

To celebrate the official inauguration of Zeds 2.0, Aamna Saleem brought this cosmic version of a cheesecake. Thank you, Aamna!

It is finally ready! The extension to the original Zeds Astronomical Observatory, after 12 years of the initial observatory construction, is finally here! Enter: Zeds 2.0 ! An observatory that can house 3 telescopes at any given time, ready for use.

Cutting the celebratory cake for Zeds 2.0

The inauguration day was celebrated by setting up Sameer Rashid Shami's Celestron 8SE telescope on top of the Celestron AVX mount. Sameer had waited a really long time (almost a year) before the appropriate testing could be done (water proofing, electrical wiring and gauging weathering effects) to allow moving in the equipment. 

The Celestron 8SE on top of the Celestron AVX mount; looking rather ominous!

The observatory has a roll-off roof that is more than twice the size of the original telescope room for, what can now safely be assumed to be Zeds 1.0! Currently it houses 2 telescopes. One being Sameer's 8" SCT on a Celestron AVX mount, the other being CBSAP 127mm Apochromatic refractor on a Celestron CGEM mount.

First light image from the new observatory. This image shows the galaxy pair M51 also known as the Whirlpool Galaxy, named after its conspicuous display of beautiful spiral arms. What is also evident is a smaller companion galaxy seen up top that is in a cosmic ballet with the bigger, more massive partner below.

In the coming days, in addition to imaging galaxies, star clusters and planets, the new observatory is planned to be used for gathering photometric as well as spectroscopic data for stars and star clusters as well as astrometric data for Asteroids and Comets.

Bright days (or rather, dark nights) await us in the future!

LET THE OBSERVATIONS, BEGIN!

M13, Globular Cluster

View fullsize

M13 Globular Cluster (NGC 6205), also known as Great Hercules Cluster, is a globular star cluster about 25,000 light years ( 2.36*10^17 km) away from us. It is first discovered by the famous Edmund Halley in 1714, who wrote:

"it shows itself to the naked eye when the sky is serene and the Moon absent"

William Herschel mentioned it in these words:

.. most beautiful cluster of stars, exceedingly compressed in the middle and very rich"

A distance of 25k light years and with the angular diameter of 23 arcminutes, the actual size of this cluster comes out about 150 light years. Towards the center, the star density is about 500 times more than our own solar neighbourhood. If there is a planet in the center of the cluster, the night sky would be blazing with literally thousands of stars much brighter than Sirius and Venus. 

M13 Cluster is also famous because, once we have sent a radio signal to supposed Aliens in this cluster!

Omega Centauri is the largest Globular Cluster in our Milyway Galaxy.. here is the comparison of M13 with Omega Centauri:

Minutes of Monthly Meeting: April 2016

“The highest attendance in a Lahore Astronomical Society (LAST) monthly meeting!”

"I remember when it was just 3 of us in a monthly meeting" recalled Maroof Mian, Senior Vice President of LAST, reminiscing on the old days when LAST's monthly meetings would be held in whatever cafe/restaurant was available and a fixed participant number was never guaranteed. Maroof Mian has been one of the, if not the most, consistent member of the group and has been a strong supporter of the idea of a monthly meetup. 

Maroof Mian, Senior Vice President of Lahore Astronomical Society

"It is vital to a group's longevity." says Umair Asim, the President of Lahore Astronomical Society, in reference to the importance of monthly meetings.

Umair Asim, President of Lahore Astronomical Society

As a lot of our members know already, the monthly meetings of LAST take place on the first Friday of a month at 7 pm. "These events are always free of charge and anyone can attend." emphasizes Aamna Saleem, the Event Manager of LAST, in every text message/email that she sends to registered members whenever a monthly meeting nears. Of course, this month was no different. 

All seats filled up! Its a 'go' for the presentation!

A lecturer for the Architecture Department of University Of The Punjab during the day and Marketing & Advertising Manager of LAST at night, Mr. Usman Maqsood Mirza, chose to deliver a lecture on the topic 'Colonizing Space' to a record audience of 53 people in a meeting room that can fit up to 40-45 people at max capacity. On-the-spot arrangements had to be made to accommodate such numbers, which was nothing but a very, very pleasant surprise. We at LAST are always delighted to see familiar faces show up at our meetings but without exception, new faces are an even better thing to see! We were, therefore, very happy to see that almost half of the audience members were new faces, new people from different backgrounds that we had never met before. They simply came to know about the event through social media and their friends.

Speaker of the day, Mr. Usman Maqsood Mirza

Our monthly meetings are centered on an interesting or a pressing/relevant Astronomy topic and is delivered in a very friendly, casual and a highly interactive way. The audience is repeatedly reminded of their freedom to ask any question or comment on whatever section of the presentation they have just seen. 

The monthly meeting was scheduled to begin at 7 pm but in order to accommodate the constant influx of audience members, the start time was pushed forward to 7:20 pm. An introduction of the Lahore Astronomical Society and Zeds Astronomical Observatory was given by the President of LAST, Mr. Umair Asim. He recapped all the important news and events that had happened in the past month, relevant to Astronomy, at Zeds Astronomical Observatory. We found out that a very special set of data had been taken a few days prior to the monthly meeting. Something that had never been done in Pakistan before. Umair Asim took the audience through a very important concept in Astronomy called the H-R diagram (Hertzprung-Russel diagram). He briefed the audience about what the H-R diagram means and why is it important. In a nutshell, the H-R diagram is one of the fundamental concepts in Astronomy. It is a graphical representation of the categorization of stars on basis of their luminosity (the actual output of a star irrelevant of how bright/dim it appears from Earth) and temperature. Umair Asim proceeded to surprise the audience when he showed that recently he had been observing the open cluster, M67, from his observatory using the huge 14" SCT telescope (Celestron C14) and his newly acquired array of photometric BVI filters (without which such data cannot be taken) and showed how he had himself plotted the H-R diagram of some 38 stars in the M67 open cluster, right here from the light polluted skies of Lahore! This stuff had never been done from Pakistan before! True science being done through a private observatory in Lahore. Such data sets can be sent to foreign researchers and can be used productively! The audience appreciated the effort by a big round of applause and Umair Asim then proceeded to introduce the speaker of the day.

A few minutes passed during changing of the laptop connection with the projector in order to start the presentation. This encouraged some chatter in the room which was immediately gone as soon as the presentation's first slide was up on the screen, 3 dots. Everybody expected a title slide or a pretty picture of some future-sci-fi graphic showing a humanly figure, silhouetted against the surface of Mars or the Moon looking at the distant Earth, from the backyard of their new space colony or something! But all that there was were 3 white dots on the otherwise black screen and then this appeared...

First slide of the monthly meeting, a rather successful attempt on April Fool's!

You saw that right. "Lahore Astrological Society" with the topic of "Horoscopes". Now, this might make a few people excited but I can assure you that Astronomers are not one of them! Everybody immediately recognized the whole deal with this slide as the next slide was shown which had a big "APRIL FOOL's DAY" on it. This made for a very interesting start to the presentation and no one really saw this coming. The laughter was audible and this helped get the audience comfortable with the presenter and the topic, something that is valued greatly in a LAST monthly meeting presentation. 

Usman, busy in unwinding complex architectural ideas into simple and easy to understand concepts.

The presentation proceeded to first show classical ideas that popular sci-fi novels and comics had portrayed regarding human exploration of the space around Earth and specifically the establishment of human settlements on the lunar surface. The whole idea of humans colonizing another heavenly body, and that too the Moon which is the closest celestial body to Earth, had shown to be around for a long time and was no stranger to the world of science fiction.

The presentation revolved around the content of Usman's thesis work which had been done on designing and sustaining a lunar settlement for humans, set roughly 100 years in the future. NASA's budget was shown around the years that had the space race hit it's peak and the exponential increase in the NASA budget during the early and mid 1960s was correlated with an increase in the number of MPhil and PhD students turnover in the USA. These two data sets were clearly related to each other.

Correlation between NASA budget and technical PhDs

 A highly detailed insight to the location, structure and operations within the lunar settlement were shown. In what was one of the most remarkable visuals in the presentation, a crater on the southern pole of the Moon called Shackleton was shown in a time lapse 'video' made by taking actual satellite images from lunar orbit, showing the changes in shadow on the crater and its rim during 1 lunar day (which is equal to 1 month on Earth). Due to its location (near the south pole), the floor of this crater (bottom of the bowl) remains in constant darkness as the Sun never goes high enough at the south pole of the Moon to shine it's light directly overhead into the floors of such craters. The animation was hauntingly beautiful and gave the audience a very easy-to-understand perspective of why this crater region was chosen for a future human settlement on the Moon. Usman grabbed the conveniently placed lunar globe to demonstrate the location of his proposed settlement.

Using a Moon globe to show the location of the proposed settlement site

Usman gave many reasons for this site selection.
1) Presence of water (in the form of ice) in the permanently shadowed crater floor, nearby.
2) View of Earth from this site; which would appear very close to the horizon and will always be there no matter what time of the day/month/year it is (yes, that is true!).
3) The length of a day on the site at which this settlement will be made (on the rim of the Shackleton crater) is much longer than, say, the equator of the Moon. This would make sure the power derived from solar panels is maintained for longer periods of time. 

An oblique view of the Moon's south pole region taken by the Japanese lunar orbiter satellite, Kaguya/Selene showing the Earth and some lunar features. Notice the Shackleton crater.

The audience actively asked questions, a lot of questions during the progress of the presentation which were expertly handled by Usman. He had certainly done his homework on the topic and left no questioner unsatisfied. 

Usman then showed the ways in which life can be sustained within the settlements i.e. crop growth, basic life support, 'crew quarters' and living apartments. One of the most interesting things that I'm sure everyone learned was the complete uselessness of stairs in the lunar gravity. It turns out that in 1/6th the gravity of Earth, every time you would take a step on a stair step you would jump higher into the air for a lot longer than you would on Earth. This would make stairs rather a nuisance than a benefit. Therefore, no stairs shall be used and they shall be replaced by gently inclined ramps. Questions like meteor impact protection and communication with Earth were asked by the audience. The role of clear glass windows was emphasized by the speaker on grounds of keeping the crew/settlement members help stay away from things like depression and the feeling of loneliness.

This lunar settlement would house 150 people, each given their own area to grow their own food. It was shown that the bioregenerative 96000 square feet crop CELLS would be divided into sections of area 500 square feet each, in order to protect the remaining crops in case a fire breaks out in the crop field. The settlement was shown to be made on the slope of the crater wall in order to protect the settlement dwellers from the harmful radiation of the Sun. Plants would be grown preferentially in hydroponic solutions to save the cost it would take to bring an equal amount of soil from Earth on a rocket. 

Usman showed how he had taken help from some people within NASA. People working specifically in the NASA Ames Research Center who replied to Usman's mail and sent 2 very helpful books to him for his thesis work which would ultimately make this presentation possible.
The presentation was concluded shortly afterwards. A Q&A session followed which lasted around 15 minutes. All members in the meeting room were directed to a group photo outside the room, near the lawn. This was the only time when the group photo was taken in 'panorama mode' of the camera simply because of the sheer number of the people that were present! Refreshments were served to the participants and a lot of post-presentation chatter filled the meeting room with some people leaving the premise for their homes and others staying a little longer, indulged in discussions on topics both inside and outside of Astronomy.

We thank everyone who participated in the event. Special shoutout to the President of LAST, Mr. Umair Asim and Event Manager of LAST, Ms. Aamna Saleem for organizing and managing the event superbly and of course to the speaker himself, Mr. Usman Maqsood Mirza for delivering a wonderful presentation on a different and difficult topic.

March 2016 Monthly Meeting - Almost Messier Objects

Monthly meetings are a regular feature of the Lahore Astronomical Society where a speaker chooses any topic related to Astronomy and gives an informal presentation that is kept audience friendly but informative at the same time.
March's monthly meeting featured Lahore Astronomical Society's Secretary, Roshaan Bukhari, giving a presentation titled, albeit obscurely, 'Almost Messier Objects', which revolved around a whole new category of interesting and relatively easy to see deep sky objects that are not a part of the famed Messier catalog. These objects that did not make it to the Messier catalog are part of what is called the Caldwell Catalog. Named after the famous British astronomer, Sir Patrick Caldwell Moore, this catalog is an amateur astronomer's guide to the wonderful objects that were deliberately, and in most cases unknowingly, missed by Charles Messier in his search for comet-like objects. 

The presentation compared the Messier catalog with the Caldwell catalog to make clear the differences between these acclaimed collection of deep sky objects. A handout with a printed map of the night sky, marked with every object of the Caldwell catalog was also distributed among the audience.

The session was highly interactive and the audience, as always, was encouraged to interrupt the presenter at any point for questions or comments. 
Soon after the presentation, it was time for the group photo. More than 35 people showed up for the event and that included kids from Lahore Grammar School and staff members including the Administrator of Junior Boys Branch of LGS, Mrs. Shaista Irfan. The event took place at Zeds Astronomical Observatory's meeting room.
