Guide scope mounting

Post by geobike » Sat Jul 28, 2007 2:55 pm

Most people are using guide scopes instead of off axis guiders because so many more suitable guide stars are available. What would be a nice way of mounting the guide scope is with the front ring mounted to a pivot and the rear ring on a horizontaly and verticaly adjustable mount. This way you can center your object in main tube and adjust guide scope to find a good guide star. If you really want to go all out have the adjustable end motor driven in a search pattern until a guide star is found.

I can always dream :D

You can get manually adjustable rings at:

I use these and it works great. I too have thought about motor driven adjustments on the rings, and even built up a prototype. It worked, but not very well. I am trying to think of better ways to implement the adjustment mechanism.

Thanks for your thoughts.

Depending on your guidescope and guide camera setup, you might be able to use the Orion X/Y guide star finder

It's mechanical, like a standard focuser but one could build a automatic motor like the Orion AccuFocus to mount to the x and y knobs and control it via a simple computer program.

Just a thought. Instead of moving the whole guide scope within the mounting rings.
