20", 250x, SQM 21.4, seeing 1", elevation 4800 ft. Component B (IC 5359) is a very nice flat edge-on. D (IC 5351) has a bright star on its S edge. Component E is the faintest, smallest group member (PGC 72405). Two stars W of it (upper right in the sketch) are V mag 16.4 and 17 in USNOA2. Sketch on black paper, finished at the telescope.

Wow,there is so much that's unique about this drawing.Kudos for observing and drawing a group that most of us will never get to see.The fact that you were able to see and note a 17th mag star is extraordinary.This is a really fun post!             Michael

Thank you, all. Michael, I try to record the faintest star in the field, especially if it is around V mag 17, as an indication of how deep the view was. Stars seem better for this than fuzzies.

This is impressive!!!  Those are some mega faint objects. Nicely done!

What clarity of vision for dim objects. How did you manage to draw this at the telescope?

Thank you. I have a bit of practice finishing sketches at the telescope. Usually a field like this is drawn from memory immediately after observing it unhurriedly. When I observe, I go slowly from star to star, from galaxy to galaxy, and from a structural feature to the next, building up a mental picture and a mental catalog of sorts. That would actually be the same if I didn't want to sketch but just take written notes. Then it only takes a few minutes to commit it all to paper. I sketch in defocused light of my red headlamp on a kind of card table and a sketch pad. It helps with preserving my night vision that the paper is matte black. I realize that the result is not really drawing-quality (vs. what could be produced by re-drawing or finishing in daylight, or even by going more slowly at night), but that's fine with me.
