I'll add that component D was tough, but I did it by positioning it so it would drift WITHOUT that "blazing" 10th mag star popping into the field. It helps to use a very narrow field eyepiece, such like what I used...a 4mm Supermono eyepiece. Notes below:

Almost stellar. Held most of the time with averted vision. There is an obnoxiously bright mag 10.1 star sitting 1.1’ north. The key to detection is to keep it off the field, so I used the 4mm Supermonocentric eyepiece giving 573x with a little 3.1’ field. Tracking was a little tough, but fortunately I was able to find a way for the field to drift without letting the star pop into the field.
