Then I switched over to the 20-inch since seeing was supposed to be good. It was ok, a little variable, so I switched between the 7-inch mask and full aperture. It was not really good enough to push limits. But having goto really saved time and I saw a lot. I ended the night with Saturn, which looked really good at full aperture, seeing all the moons and the darkening at the pole.

Warren, and his paper is not coming up on the internet. He has a 1902 first discovery date, but he lives published in the 1990s, so it's difficult to tell what this is. I suppose because his paper is not readily found the stars are not listed in the WDS?
