have done some more playing around with the st-2000, this time with a 55mm camera lens at f/2 and an Astronomik H-alpha filter. Gamma Cygni region. 2x5min median combined. Modified levels and curves, slight unsharp mask followed by slight gaussian blur. Also cropped a wee bit (I had a dark spot in the corner, I forgot to remove the top counterweight from the 11" it was piggybacked on) and image size reduced a tad to save herb's space. In the future, I'll combine more exposures. Love your book so far Ron.
