I had a chance to try my TSAPO65q on the Star Adventurer... Well, used to the 300 f/4 focus and framing has been a pain... But in the end i won the fight. Pointed at NGC7000, i took 1 hour worth of subs, wasted around 20 mins because i put sincro-x instead of bulb after a fast look at subs from the lcd, and in the end i got only 14 subs with round stars. I can't so tell about "good subs/total subs" ratio. this is a 120 sec, 1600 iso, sub (White balance and a slighty shift on curves only on Capture NX2) DSS result (14 Light, 47 Dark) First develop: Here's the setup shooting Unmodded Nikon D610 camera, all unguided (obviously).
