Like your thinking regarding days off and imaging Narayan
I see what you mean about the coma but it isn't that distracting for me really. The lens on this scope was never designed to work over a chip the size of the 300D. I didn't think a FF was available for the 80ED's.? Otherwise they are very nice images with good colour processing. The pink/red in Eta may be a little saturated for my taste but is still a rather pleasing rendition of this southern favourite.
My favourite is the NGC 3766 cluster. I like open star fields with clusters appearing superimposed over the top. Here is an image I took of NGC 3766 in close up, a couple of years ago with the 12" SCT
