Hi Chris,
Thanks for the information. This really helps others gain an understanding of your technique.
Fahim and Mike have good advice. Less compression would be good. On my webcam you can achieve this by reducing the frame rate to 10fps and using a better codec. You can do the RGB alignment in Registax. As Mike is saying, RGB alignment makes a significant difference.
Looks like you're getting about as much image scale as you can with the afocal setup. It's not expensive to dabble in prime focus. You already have a barlow and the SPC900NC webcam cost me $89 around Christmas time. You also need a Mogg adapter for around $40 to rigidly mount the cam to the telescope.
The SPC900NC + Mogg adapter is a low cost and very versatile setup.
Anyway, I'd be very excited if those were my first images. Great result given your equipment.
Have fun,
Doug
