I ran across this little jewel a few weeks ago while hunting up something to image with the Mach2 and 160EDF refractor, using unguided exposures. The open cluster NGC 6791 has a dozen or so bright (mostly red) stars in the foreground and thousands of fainter blue ones hiding behind. Taken thru murky skies during a summer heatwave that won't quit.
