NGC 1788 - A reflection nebula in Orion

Orion is dominated with many Deep Sky Objects; the crown is of course the most imaged nebula, M42. In the same constellation lies a reflection nebula which is cataloged as NGC 1788.

It is 1300 Light Years away from us and is located about 5 degrees North from Rigel. It contains extremely young stars and shines with the reflection of these stars’ light.

Image details:

Telescope: Celestron C14

Camera: SBIG ST9XE

Filter: Astrodon Luminance

Mount: Losmandy Titan

Guiding: Autoguided with SBIG Adaptive Optics at 6.4 Hz

Sub Exposures: 5 minutes each

Total Exposure time: 100 minutes

I do need to collect more photons from this object which i will in coming nights. I will also image this object in Infrared band.

Oh and btw, i have shrunken the fat stars in the picture :)

NOMAD shows that at my location with Luminance filter i can go a bit beyond 18 magnitude around 50 degrees altitude south side.. it is two magnitudes deeper than my previous location.


Above is the graph of autoguiding errors from The Sky X Pro.. Left side is the latest. Notice the ‘Guide Star’ was behaving a lot better a while ago but it started to jump all around before i stopped the imaging run. This happened because the Seeing got worst!
