Greetings All, 

 

Here is an attempt at the Owl Nebula, M-97 and M-108. This is from a Canon 60d, 135mm, f/4, ISO1250, 30sX80 stacked in Siril. Mount was a Sky Watcher Star Adventurer GTI. This is from Bortle 8 in N. Las Vegas, NV. last night (5.16.24) with a 61% waxing moon phase. 

 

Fun stuff.

There's a small amount of elongation to the stars.

 

It's not best to use "in-between" ISO settings, so I suggest you try 1600, and 800 if that's too noisy.

 

And reduce exposure time until you can't see drift, and take more exposures to compensate !.

Thank you for the comment. The moon didn't help matters for sure and this was more or less the first night without wind, rain, or else.  As much as I have read on the mount, I find it's still a bit 'wobbly' to the slightest vibrations even with everything locked down. 

 

Additionally,  gaining focus on the camera is a bit problematic as well, even with a Bahtinov mask for the lens with glasses. Once I got the mount aligned, and started shooting, I realized the ISO may be a bit high. I can see how having a multi-thousand dollar computer setup make things easier. HA!
