That's right, I use a 4 ince refractor, on a celestron nexstar SLT mount. I don't dare, try to track satellites using the scope on the mount. Why, because I don't want to risk, having the tube hit the mount, as once happened. After which I had to send in the mount for repair. The reason I use a wide feild, for satellite tracking, is because of pointing error's in the mount. Doesn't matter how much I do a good alignment, the satellites are not placed, close to the centre of the feild of view. So having a wide feild, is important to making sure the satellite is in the feild of view. Handy on some nights it's clear, when I am working. I just use goto mount to track a flashing geo sat, and record the video for later playback. So no need to stare at the geo sat waiting for it to flash. Once I know where to look, then I can view it on a night I am not working. But if I am looking at high up satellites, then having not as wide a feild is ok. I just allow for error's, when trying to locate the sat. Since they move slow, plenty of time to locate it. I have more interest in observing high up satellite, ie geo satellites and such. Not that you couldn't tell with my post. Kevin __________________________________________________________________ Be smarter than spam.
