NGC2403 a spiral galaxy sitting in the constellation Camelopardalis. This is one galaxy I am not very familiar with and only happen to image it because of looking at options online at Deep Sky Objects Browser.
This frame is slightly cropped due to the star distorts at the edges because I do not have a corrector in the imaging train and the D5100 has a large enough chip to see the ugly uncorrected FOV. I do have a AP corrector/reducer I will try and make work like I mentioned in the HH image posted earlier in the week. Sadly, there are not many clear night this time of year to test things out.
I sure can tell my PI processing skills are increasing with this image. The subframes barely show the galaxy and the data collection runs started with it below 45deg and in fairly heavy LP. Also shows that piles of subframes can overcome LP and still make a red zone location productive, even with broadband imaging.
