Quote:Sure, you could record PEC. But 500mm is a pretty long focal length and probably a minute or maybe two would be the limit unguided assuming good alignment and balance. If you have a guider why not run that when the camera is mounted?
Quote: The fact is, I am not/was not sure I can use both the camera+lens AND a telescope+guider *simultaneously*. Hence my asking about first training the PEC, then using the lens. Is THERE a way to have these two at the same time on the VX mount?

Quote:Orion and others sell a Vixen compatible dovetail with a 1.25-inch bolt (like on a photographic tripod) that will allow you to attach a camera or a camera + ballhead.

Is THERE a way to have these two at the same time on the VX mount?There are a couple of ways to do that.#1 (this is how I do it) is to get a dovetail bar that is something like 7" long or longer, then on one end attach a camera ball-head (...) to secure the camera. On the other end of the bar attach a finder scope base so you can mount a 50mm finder-guider. (...)#2 would be to use a telescope as your guide-scope that is large enough to allow the camera to Piggyback on the scope. (...)
