Well it is not released yet but I was thinking about getting a modded DSLR after a couple of years of fun with my 20d.

The specs on the 450 sound very appealing - all the benefits of the 40d without the cost and at lower weight too...I can wait for this so then I got to thinking about the scope.

With my current setup I am already oversampled - native this gives me 0.73" per pixel, with the FR 1.16"/pixel. My main interest is imaging DSOs and I am N of Sydney - my seeing is 2-3" at best.

So what would be a good match to a 450d - 12Mp sensor both in terms of FL, resolution, flatness and $$.
