I tried an experiment during my vacation in August: hooking up the AP-6E to my 120mm f/5 Orion refractor. Serious curvature, and a scale of between 8-9"/pixel, but it makes guiding easier.

Here is NGC1499, with just under 5 hours total exposure (10 min subs)

And here is a two frame mosaic of the Pelican/North America complex...you can see the curvature in this one, as well as my bad CCD columns here and there....
