Thanks again Matt. That's exactly what I needed to know.
I think I'm going to bite the bullet and order the microfocuser. If I could get a smooth focus adjustment at 10x the resolution I'm seeing now without the image shift that would be a great help.
My focus knob is quite stiff and I need to shake the tube a lot to adjust it just a little (I did buy the scope in 1999). From what I saw last night, I'm sure I could find a good focus just watching the image on the screen if I had better focus control.
I won't bother with a Hartmann mask or IR filter for now.
Thanks again, particularly for the capture settings.
