Description

This one is quite a stretch for my 430mm focal length scope but I've given it a good go over 9 nights between April 2022 and May 2023 and am fairly happy with it.
8 hours of 120 sec subs unguided with no filter plus 8 hours of 300 sec subs with Optolong L-Pro filter and PHD2 guiding. This is quite heavily cropped. Quite pleased to have resolved IC4263
