Back in Culebra I attempted collecting Thor's Helmet (NGC 2359) with the Edge HD11, but at that time I was still using the Celestron CGX mount and the ZWO ASI294MC Pro, a one shot color camera. I don't remember what I was using as a guide scope but I don't think I spend enough time on it and the tools available for processing the images weren't what they are now.
Here is that first image, kind of faint but true color:
Not too bad but definitely needed more time on target. I think at the time I was learning to use the Edge HD11 and the difference between coming from the RASA 8 which is a very fast focal length to this much slower scope that requires a lot more time to gather the same amount of like.
After "some" equipment upgrades... ok, really only the scope and the focal reducer is the same... I decided to go after this target again. This time since I'm in Austin now with narrowband filters... I do miss those Bortle 2 skies above Culebra. This time the total integration time was 8.5 Hours over several days of collection. The new equipment definitely helped but the overall step in Astrophotography Processing tools and scripts has jumped immensely since I restarted in 2020. Overall I'm really happy with this image as I think it has the details that are needed to show all the unique structure in this heavenly object.
