My first attempt at a comet with a monochrome camera and RGB filters. That alone was a challenge, plus the pinched optics did not help either. Certainly no my best image ever but it's all part of the learning process. Undoubtedly a OSC camera would have made some of this a little easier. I'm certainly finding out that OSC certainly has areas of astrophotography where it has an advantage over monochrome.
