Last night we had a rare clear night, so I pulled the iOptron CEM25P onto the roof and captured the Rosette in Ha.
Polar alignment was spot on (with no view of either pole at the equator) and tracking was fantastic.
Your Rosette is very stunning! It beats mine hands down, but I think you should try to add OIII for color like I did here, it would be spectacular. I made the Red channel Ha, and the Blue and Green channels both OIII. You have better Ha data to start with, plus your field of view is more appropriate to the object, so it should be great!
