2019 November: Complete LRGB Tutorial of NGC292, The Small Magellanic Cloud by Christian Sasse, Astronomer in Charge of iTelescope.net
2019 September: Astro Pixel Processor and iTelescope.net celebrate a new Partnership!
My learning continues. This is Andromeda -- essentially my second astrophotograph. Taken from my backyard in DC (bortle 8/9). I need to do better at removing light pollution.
Taken with a William Optics Redcat and ZWO ASI294MC Pro OSC, Takahashi PM-1X mount. 15X4 minutes each.
Many thanks, Vincent! I did use some calibration files -- 30 each of bias, darks and flats. I suspect that my flats did not come out too well because when I stretch an individual flat (or the master flat), I do not see any gradation in the image, etc. I find it hard to believe that the scope has zero vignetting. I need to learn how to take proper flats. The darks, on the other hand, show an amp glow very clearly.
