Notes:

My largest field of view is with this eyepiece, 49 arc minutes. So, I can only see the entirety of this object in the finder where the long side is about a quarter of the view.  I wonder what Messier saw with his long focal-ratio telescopes and narrow field eyepieces.

My main instrument shows huge obscuring dust clouds arrayed along the NW edge of the cloud. The largest is about 1/3rd of the field in diameter, so about 16 arc minutes. Generally the dark areas are not simply black, they show shades of black and look smoky. A bit over half a degree S, on the other side of M24 is NGC 6603 a neat, round, dense star cluster which seems fully resolved. Its stars all appear of a similar magnitude, not much variation.
