Galaxies around M57

I stretched the 600 second Luminance exposures to show a lot of small galaxies in the area around M57. Although the seeing was very good, there is considerable light pollution at my site and the Moon was up on those two nights.

Thank you all for your nice comments.

Just want to point out that an F14.6 optic can indeed be a deep sky imaging system. The main criteria for imaging is signal/noise which is determined primarily by aperture, not focal ratio.
