Finally got a galaxy other than M31 and the Milky Way! To get the object centered, I used the telescope setting circles. I set them on Arcturus, the brightest star in that area. Then I moved the telescope to the catalog position and took a test exposure. The galaxy was in the upper right corner of the first frame, so I made a couple small tweaks with the control knobs to center the galaxy. I never saw the object through the telescope. This is a way I can continue practicing astronomy even though my glaucoma makes it difficult to look through the telescope. With more practice I will get even better.
