Lyra Constellation with Star Labels, DSLR with 110mm Lens

lyra labels 110mm
3 min 7 sec exposure comprised of 75 subs, 40 darks, 40 bias, each at ISO 1600, f/5.6, 110mm, 2.5 sec
Before Lyra sets in the evening sky for the season, I wanted to get a good stack of the entire constellation. My result was the equivalent of a 3 minute exposure using 75 light frames at 2.5 seconds each (longer than the typical 1.3 sec because I wasn't zoomed in as far).

The faint Ring Nebula is visible as a blurry dot in the base of the harp, and double stars abound throughout the constellation.

Astrometry was helpful in wrapping my head around the raw image with its useful labeling tool. Here is the resulting image from the site.
