I took some photos from my place last night to try a few things out, the first of which was doing LRGB from my house without a moon. The second was to use flats from a different night of imaging. I think with some targets I might get away with doing LRGB from my place, but the flat idea was a bad idea. I will just take new ones each session.
This is a quickie of m20
15 minutes of each filter
3x5min luminance
5x3min RGB
Yea, I got these last night from about 1030 till midnight, then it clouded over. Shorter subs seemed to work better from my place, but there was still a horrible gradient. Its amazing how much the light pollution effects the photo.
Thanks guys, I struggled a bit with the red emission colour maby adding some HA could have helped me get that red I wanted. The other area that was a bit of a pain was the right half of the images background is noticeably more blue than the left.
I live about 15 km as the bird flies from Adelaide. I was really happy with the star colour, and I seem to be getting more reproducible results night to night with collimation and coma. At the end of the day I probably wont do any LRGB projects from my house but I know when I get full narrowband filters that i can add RGB stars to the mix reliably.
I hear that the QHY22 will be out soon with
latest Sony super sensitive chip – ICX694.
It is however maybe a bit small:
Resolution: 2750 x 2200 pixels; Pixel size: 4.54µm x 4.54µm; Imaging area: 12.49mm x 9.99mm
