This is a tough project for me. Only 26 degree above the horizon. I almost gave it up and finally decided to try this. The object is very bright and full of Ha. The FWHM of luminance subs were around 3-3.5 arcsec, which were not ideal and the star shape was not that perfect due to the guiding. Therefore, the final image is not that sharp. I cannot compare it to those who imaged it from the southern hemisphere. However, I finally did it within the only 2 clear nights in this month, and now I have both northern (M101) and southern pinwheels (M83) in my handslol.gif

Not enough time for Ha yet. Just LRGB. I tried to take some Ha at home, however, I found my backyard fence blocked the scope since this target is so lowgrin.gif

Looks fantastic! Really nice colors!

 

P.S. The collimation looks very good as well...that's tough to get right on the RC8 scopes!

Thank you John. Collimation should be good. I do find a lot of tricks to use this RC8lol.gif
