I've never before spotted something moving while looking through a telescope, and then it happened 3 times over the course of 2 days a couple of weeks ago. One of them was an airplane, which I won't really count. But the other two were very, very high and clearly not airplanes. Each was maybe about the brightness of a 12th magnitude star (give or take; just a guess) and moving very, very slowly. The first was actually spotted by my 8 year old son while we were looking at the Andromeda galaxy in the 10" Dobsonian (1200 mm focal length, 15 mm 100° AFOV eyepiece with 0.5X focal reducer, so 1.25° FOV). He likes to tell stories so at first I didn't believe him, but I looked and sure enough there it was. I tracked it for almost 5 minutes before losing it behind the trees over something like 5 or 10 degrees; I'm not sure exactly. About the length of Cygnus, nose star to tail star, however much that is. It was moving directly for Polaris, so I presume it was a satellite in a high polar orbit.
The second time was a couple days later, through the camera. I had shot Jupiter and Saturn and was playing around with the settings to see how faint I could observe untracked. Scope was pointed basically straight up at a patch with no bright stars, magnification about 240X. I was twiddling settings in SharpCap to where I could just barely see faint stars drifting across the screen when I saw another faint "star", about the same brightness, drifting across the screen at a somewhat acute angle to the background stars. Since the background stars are drifting in right ascension, I presume this was another very high polar orbit satellite, although I have no way of knowing.
Finding 2 very high, faint moving objects in 2 days with a telescope seemed like it might be a once-in-a-lifetime event to me. Anybody else ever spot something moving in a scope?
