Here is a couple hours of LRGB on M53 taken at Harold Campbell. Originaly I set out to image a M106 or M95 but had some issues that took about 90 minutes to work out and by the time I was ready to go it was 10pm, not enough time to do those dim objects. I settled on M53, It's bright enough to get a decent amount of data in 2 hours.
Still manually focusing with this new scope I was able to get a FWHM of just under 2. Better than the previous focus I had on M3 and noticeable in the rounder stars in this image.
I have 8 Luminance subs at 300 seconds and 7 RGB subs at 150 seconds.
I used flats and darks taken from the previous outing.
Images were calibrated and aligned in Maxim.
Stretched and DBE done in pixinsight.
Final star color boost in Photoshop.
No noise reduction on this one, surprising to me because I didn't have a lot of subs.
