Agreed, downsizing (even Hubble) images can make them look like they are just average res, but I figure 1400 by a 1000 odd is big enough for public forums.....and is larger than many of the posts here on ISS.

My estimate is: the RC was delivering about 4x (in area) smaller stars than you've linked to.

Sure, the focal length and AO helped quite a bit IMHO, but the seeing on the night was pivotal.
I guess the 7nm Ha helped shrink the stars a bit too..? If I had a PME and larger objective plus a permanent obs I'd have gone for the Astronomik 6nm set rather than the 13nm that I did but I had to weigh it all up I guess.

Your final image is sure to be excellent and it would be great to see it in fuller res....before the David Malin awards

Mike
