For some time I owned a Celestron 9.25" SCT and I quickly found the observations I made with it were very similar to what I had seen in my Nexstar 11 GPS from years ago. But, one of the objects I did observe with the 9.25 inch was NGC 1023, a galaxy. With a 14mm eyepiece it was pretty bright, pretty small, elongated 2.5X1 and much brighter in the middle. Averted vision makes it larger and more prominent.
Using a 13.1" f/5.6 on a terrific night (S=8 T=9) over 100 miles from Phoenix this galaxy shows lots of internal detail. At 100X it is bright, large, very elongated 3X1 in PA 90 and much, much brighter middle. Raising the power to 220X brings out several brightenings in the outer arms (stars or H II regions?). Averted vision makes a huge difference in the length and thickness. The higher power also shows a very faint companion to the east.
