Here's my 2nd image of the night. M13 with the OSC camera ASI071MC Pro, again just shy of 1hr. Need work on focus with this camera also the flats are just not 100 percent, need to figure out the ideal ADU for this camera, I used 25000 for this camera, still not perfect as I see some artifacts. Haven't been using my OSC cameras for over a year now so I have to re familiarize myself with them.
