Description

Here is NGC 2903! Used an off axis guider for this image, and I was able to get it working out of the box which is a first for me. Captured a lot of great detail in the inner galaxy, but struggled a bit in the faint regions. For some reason, my flats slightly overcorrected, leaving bright donuts, so I could not stretch the image as much as I wanted to. Perhaps this was for the better, as the outer spirals were already quite noisy.

Taken at gain 200, I think next time I'll go for gain 139. The light pollution takes a serious hit on my dynamic range at such high gain, so a lower gain might be a better idea.
