Looking very fine indeed. Lots of yummy detail and some good background galaxies. Congratulations.

Your high-res is 31 megabytes. Given the realities of seeing and guiding, unless you're in the Atacama or Mauna Kea or Pic du Midi, land-based astro-images at this image scale can be JPEG compressed to about 2 megabytes with no important loss of data.
