Star field around NGC6556

starry-background.jpg

This is the first shot taken using my new coma corrector + adaptors! There is still some distortion around the outer edges of the image, but it’s a much flatter field compared to before.

This is a stack of twenty¬†5 minute exposures, but no dark/flat/bias frames were used. I have to take new flats since I’m now using the coma corrector, and I haven’t been able to take any darks at a cool enough temperature yet.
