    Notes I'd been wanting to image this galaxy for a long while now but never had the focal length available to do so and still get a decent result. Even 1050mm is bit low. I'd really like to image this and NGC4565 at about 1600mm-1800mm and see what that yields. I was actually performing a side by side comapriosn while imaging this target against an Astro Physics 160 EDF Starfire. The results were very surprising and I was happy make it happen. The AP image, as well as photos of the setup will be listed below.
