Description

I was not happy with my last capture of M33 - focus was off. I tried harder this time, and went back to using SharpCap's FWHM focus tool - my favorite so far. SGPro's HFR tool is nice for a frame to frame comparison, but for nailing single star focus (prior to slewing to target and final framing), I really like the FWHM method.

I got an early start this night: was imaging by 7:00 pm. This image represents about 2 hours of integration. Sky was totally clear and transparency was great!

Thanks for looking!
