Hi Folks;
Here is the preliminary color version of those faint galaxies around NGC 7720 :

and then the Luma image inverted to show the faint fuzies in the background:

It stayed clear last night (August 23), but turbulence was higher (FWHM 3.5 to 4.5 arc seconds / Guding RMS 0.8+ arc seconds) and I had surface winds to 50+ kmph, so "Stephen's Quintet" is a bit soft.

For comparisons sake under superb seeing conditions (1.2 arc seconds) see:

It's supposed to cloud over +/- rain tonight and rain all day Saturday, so these will be my last vacation images.
TTYL..
