I wanted to do some test imaging before doing any more work on the optics and last night the sky cleared with the moon putting on a low 35 degree altitude appearance.
Visually, with a 5x Barlow and 20mm eyepiece, giving 112.5x magnification, the moon looked nice and crisp with very well defined focus.
Then I captured a 1000 frame AVI with my unfiltered ASA120 mono cam.
So the attached image is wide spectrum, not even IR/UV cut filter used, and it should show a lot of atmospheric dispersion if I had used a colour camera.

I think that all I need to do is a bit of figuring to reduce the astigmatism and then I can move on to doing all the final coatings.
