Nice work. What camera are you using? Are you really taking a 10 minute video of the Moon here? How are you stacking the video and are you doing any sharpening of the image. I'd be interested to see what your results would be like with that telescope if you put a 2x Barlow on and used it at f/16.

Camera used is a ZWO ASI183MC, and yes that's a 10 minute video, stacked, approx 10 frames a second. ASIVideoStack as part of the ASIStudio suite used for stacking, with slightly added sharpening.

As far as using a barlow lens, keep you posted on that, have a x2 2" Barlow, just haven't used it as yet.

I'm no expert, but I would explore if you can get a faster frame rate by reduce the region of interest on the camera and aim for 50 fps and maybe try stacking 30 seconds worth, a minutes worth etc. I'd also watch the histogram whilst imaging and reduce the gain or speed up the shutter speed to make it a bit less bright. But good work.
