This is the first light of my new ToupTek ATR533C. I switched from a stock Canon EOS 250D and I wanted to see how big the improvement was, so I decided to choose this target, because it's also the last one I did with the Canon.
Immediately, I saw I was getting so much more Ha signal than with the Canon. Also, I really liked the fact that I could make my dark frames later in the day and didn't have to lose time at night.
Overall, I am really happy with the picture, considering it's my first attempt with an astrocamera and it was taken under the full moon. However, I think I could do better with the processing – I will probably come back to this data again later. The one thing I would try to do better is the star processing as they have weird color probably due to the dual narrowband filter.
