Pervez Hoodbhoy lecture on 'Gravitational Waves'

As soon as LIGO team announced the detection of Gravitational Waves, the world of Science was taken by a storm of.. well.. waves and waves of excitement!

Dr Pervez Hoodbhoy is a highly esteemed and prominent scientist in Pakistan. We requested him to enlighten us about his monumental success of Science and Mathematics.

Hoodbhoy so kindly accepted our request and on 23rd February, 2016, he gave us a great presentation on 'Gravitational Waves, Discovery and Detection'.

Here is a complete recording of his lecture and Q&A session with members of Lahore Astronomical Society. The lecture is available both on Youtube and Vimeo.

Our Boiling Sun

Just like our earth, our sun's internal structure has different zones. Underneath the solar surface, which is called the Photospehere, is a 'Convection Zone'. This is where the internal material comes up, cools down and then falls back. Hence we see a boiling effect on the surface.

Here is the super magnified version of the same image.. every bright round dot is called a granule which is about 700-1000 km in size, having a life of about 10 minutes.

Triple Sunspots

So white light can show amazing details on the solar surface. Granulation, which is the 'boiling effect' due to convections zones on the surface, is clearly seen. But the most amazing sight is the sunspot.. and how about one not two but three of them together!

Took this image today, with CBSAP APO 127 mm refractor telescope attached with Imaging Source DMK21 CCD camera including a 2.5 powermate in between.

New equipment at Zeds

So i have been doing photometry with Astrodon V filter for sometime now. But i wanted to do more science at my observatory. 

For Photometry, next step was to invest in more filters. Recently ordered Astrodon Blue and Infrared Photometric filters and they arrived yesterday.

With these filters, i also got Bahtinov Mask from Farpoint which will be used for CBSAP 127mm APO refractor.

These filters are now in place with their other cousins in SBIG CFW10 filter wheel.

Now where is the clear sky? 

Hamari Kainaat - Episode 10

 "Hamarai Kainaat" episode 10:

In this episode, we talk about the new findings of exoplanets' possibility in globular clusters and what impact it can make on any possible alien life in the system.

Solar Imaging.. once again!

After a long time, i have started solar imaging again. This image was taken today with Lunt 152 Hydrogen Alpha Solar Telescope and Imaging Source DMK21 Mono CCD Camera.

Got 6000 frames and selected 2000 of them and stacked and processed with Avistack and Registax. Final details were enhanced in photoshop.

Roshaan Bukhari with Akbar Sahib

Today Akbar Sahib brought his newly purchased Coronado PST Hydrogen Alpha Solar Telescope to the observatory and Roshaan and i was happy to see the details this "small" telescope was showing us.

Its a very light weight telescope but the optics are truly amazing. Sun was very sharp in the view and the typical red halpha color is always so pleasing for me.

I also tried negler 9mm eyepiece and loved the solar details. Roshaan did what he does best, when he took images from his mobile camera. I still have to see those images.

Akbar Sahib came all the way from Rawalpindi and before he left, he told me that he wants me to keep his scope for a sometime so i can further explore its capabilities. Now that is generous! 

First thing i will be doing is to attach a ccd camera and aqcuire some AVIs. Let's see what it can show us in images!

Hamari Kainaat (Urdu) - Episode 9

From this episode, we are starting a new segment of "Nai Baat at Hamari Kainaat". Here we discuss the latest news of "water on Mars" and its implications.

Let's listen to our Astronomer, Dr Salman Hameed.

Hamari Kainaat (Urdu) - Episode 8

In this episode, we discuss how astronomers learn about different types of stars on H-R Diagram, why is it so important and how easy it becomes to know the life cycle of any star by looking at its place on H-R Diagram. Let's see how Dr Salman Hameed explains it so simply.

Hamari Kainaat (Urdu) - Episode 7

In this episode, we talk about stars.. how did we first know the nature of stars in the night sky? what amazing knowledge spectroscopy of starlight has given us? what different colors of stars can tell us about their physical properties? Let's begin our journey by asking these question to Dr Salman Hameed.

Pluto, the lo(a)st planet

In March, i imaged Pluto with Celestron C14 telescope and SBIG ST9XE camera. Where is Pluto in this image? I have attached a chart here (click the image) and you can find it in this crowded star field.

This chart is from TheSkyX Pro which is a premium software used for planning and controlling all modern observatory equipment but i noticed the position of Pluto is a bit different than marked in this chart. Have no clue why it is so.

Dr Hoodbhoy's Lecture on Blackhole

Dr Pervez Hoodbhoy, honored us all by coming to Zeds Astronomical Observatory to deliver a lecture on Blackhole and Information problem, on Lahore Astronomical Society's monthly meeting of April 2015.

I am truly grateful Dr Pervez Hoodbhoy, for coming here and enlightening us about the amazing physics of Blackholes. Every participant learnt a lot from you and enjoyed your pleasant company.

Here is the recording of the whole event.

Sunset at my Observatory

Yesterday evening was beautiful at the observatory. I opened Canon 6D and took around 10 images of western sky. Moon in Hyades, Venus, Orion, Taurus, some Auriga and even Pleiades in the lower horizon.

I could spot, barely, a 5.8 magnitude of star in Pleiades.

Astronomy Outreach at LGS, Johar Town.

Ali Khan and i visited Lahore Grammar School even when it rained that day and was cloudy. Their Science teacher Shaista Irfan had arranged a star gazing session there and had brought a Meade 90mm ETX telescope.

We observed Jupiter and M42, also some bright stars as well. Constellations were identified and some of the history of Astronomy and telescope was discussed. Star maps were distributed and used by the students. Good job boys!

A visit to Punjab University, Space Science Dept

Punjab University is a big institute for educating thousands, here in my city. They have a Space Science Department and recently have showed great interest in Astronomy and observing with telescopes.

I got a call from the observer of their department and on 27th February, 2015, i went there to help them with the two big scopes they have in their department. One is from Meade with 14 inch mirror and the other is of Celestron having 8 inch aperture. Both have Alt-Az mounts.

There were some issues with initiating the power so we used it manually. Needless to say, the optics are amazing.. 14 inch mirror always is a treat to use. It was quite hazzy and partly cloudy, but still we were able to see moon and jupiter.

These images were taken by the students of the department and you can see how enthusiastically they were using the scopes. I am sure we will see a lot more coming from Space Science Department in the near future. I wish them all the Astronomical success!

LAST March Monthly Meeting

Yesterday, we had a great time at LAST monthly meeting at the observatory. As usual i started of by introducing Zeds Astronomical Observatory and what we did last month here. Our photometric submissions were 42 in total, although it was quite a cloudy and rainy month.

Rabeea Rasheed, who is a second year student of Lahore College for Women University, gave a talk on Astrobiology which was wonderfully explained. She had definitely done her homework there!

Good to see new faces in the meeting! Here are some of the pictures i took.
