Here is a sketch of M56 I drew last night. A woodcut in an 1800's observing manual shows an arc of stars around it, but I couldn't find it. Books that old are notoriously bad giving specifics about their drawings such as FOV or magnification or orientation, so modern observers are left scratching their heads about how to relate the illustration to what they see in the scope.
Basic stats: 10/18/2020, 9-10:30pm MDT, Washington, UT backyard. Celestron Comet Catcher, 5.5" Schmidt-Newtonian. iOptron GEM45G mount, sidereal tracking. Image circle is 100x at 0.45*. The observation took a hour and a half, the drawing itself half that.
Drawing materials: Computer paper on clipboard illuminated by a handheld red-light flashlight. Drawn using a Sanford Design 2B art pencil and Pentel Clic vinyl eraser (shown in the photo). Outlined a 2.5" jar lid to make the image circle.
I won't claim my drawing accuracy is any better than those old books, particularly once outside the image circle. In fact, in the image annotated with the stars' magnitudes (from SkySafari 6), the "?" stars says I didn't do a very good job since I couldn't locate them in SkySafari afterwards; they might even be duplicates.
Initially I drew just the stars inside the FOV and wrote some comments below. But when I expanded to drawing stars outside the image circle I had to erase the comments to make room, so the bottom of the sketch is a bit messy.
