I think with a better webcam (fast framerate, no compression, mono RGB imaging) better resolution can be achieved with the GSO Optics. But more aperture would be nice too! Where's the 16" truss dob when you need it!

Basically, does it need to come out, obviously with the issues of dust bunnies and eq platform put to one side for a moment.

I don't know yet, Dave.. One thing I found with the extension tube is that you need a lot more frames to stack to eliminate the nasty artifacts that come with deconvolution and heavier processing. For the small shot I stacked 150 of each channel, and for the extension tube I stacked 200 because @ 150 it looked horrible with those swirly patterns around the edges again.
I will pull it out more once I've cleaned the CCD and got my tracking smooth again, but in less than great seeing it's just going to need resizing down and I don't know if it's worth the hassle in those situations.
Thanks again guys.
