Mostly posting #Astrophotography stuff here.
I'd really wanted to get an other 3 to 4 hours of images to enhance the finer details in the nebula but with bad weather in the forecast and October/November ahead its unlikely I get an other chance this year. Especially with only two good hours a night for this target in ideal conditions.

I'm not going to lie, A Questar is a really nice telescope. Both in terms of quality and as a piece of art.

Definitely not ideal. Better would be a 200mm edgeHD with a small pixel planetary camera or something similar, but that's what I had available and it works pretty well.

Of course.
I was using a 130/650mm Newton with two barlow lenses stacked for a total of ~3500mm focal length. Tracked but unguided with a Skywatcher HEQ5 pro and imaged with a Canon EOS 250d. A bit overkill, but thats the configuration I used on Saturn right next to it.

Yes. But none of them are named stars. That particular one is a mag 15 star in the Gaia DR2 catalog. But there are also a few artefacts from the camera sensor that survived the stacking, since I used less than 10 pictures for this one.

Those are really great shots. And looking at the telescope used I am not surprised that I was barely able to image it at all

Visibility should be much better in November. Sky conditions might be tricky though in my area.
Good luck.

To highlight the position in the Image.
It's very faint but definitely in the correct position. Captured on the 18th August 2025 around 20:15 UTC.

Thanks.
