This one, Matt.. (the V-Gear)

Hopefully it will arrive by the end of the week.

I was always confident that Chris and Damien both resample - you can tell simply by looking at the image scale versus the focal length of their setup (scope + barlow + chip size of the camera). But as I said in the other thread, they have great seeing and lots of frames so that the resample doesn't look grainy and dim like it does when I do it

Robert, your comparison is a good one in ordinary seeing.. It's best to have a smaller, sharper image than a large blurry one. The type of image scale you see in Damien's and Chris's resampled images is almost impossible to get with a scope of that aperture and focal length. You'd need a big barlow + a lot of extension tubes, and perfect seeing. In the case of perfect seeing, I would expect that native focal length is better than resampling, as long as the seeing can support it.

If you have a very large aperture scope with a long focal length (like a 25" dob or something), then you could probably get that sort of native focal length as long as the seeing supported it.
