Thanks guys. I am quite taken with it for the same reason. 7 mins is a joke and there is some detail there already. I look forward to getting over an hour on the target at a higher ISO so DSS doesn't have such an issue. Confident it'll look worlds better too.

A first attempt at the Owl Nebula. Taken with my Celestron 5SE with 6.3 focal reducer and Canon SL3 camera. Had a time with the gear but the main objective for the night was only getting more familiar with the Alt-Az Goto mount and sorting out a smooth setup process. I was aiming for 80 30sec subs, since I forgot to take away the 10 second countdown timer on the camera they were only 20 seconds each. Further shortened by Deep Sky Stacker having some trouble with the number of stars in the frame, I only ended up getting 23 subs to stack. ISO for the shots was 1600 and no calibration frames were used. So short integration time it just made the final photo worse. Lastly I used a 3 times drizzle to really emphasize the noise... I mean nebula. Given the short integration time of only 7 min 40 seconds, I am pleased. A good point to work up from if there ever was one.
