The 8 inch Astrola I managed to get my grubby paws on includes a 12 eyepieces, a barlow a diagonal prism, camera mounts etc etc. Great. It also comes with a Apollo review telescope, its a D = 60mm; F = 710mm; refractor. the one thing that is missing is the mounts for this telescope. Now I was thinking of getting brackets made up from aluminium, laser cut them and then mount them. Its there a specific place to mount the Apollo out do I put it where I find it most comfortable for me? Attachments:

Hi Paul
Guide rings are easy enough to find. I may have a set you can have. The problem is adding a counter weight to offset the weight on your rotating rings. Did your scope have a small counterweight on a sliding shaft? Take a look at Jon miles restoration on the cave site to see how the guide scope is mounted and the weight offset.

Some say (me) the best place to mount a guide scope is on top of the rotating rings. That way, the OTA will not need additional tube weight to balance it out. You would still need additional counterweight on the Dec shaft though. It looks like your guide scope is not a 'stock' guide scope but something that was mounted on an alt-azimuth tripod at one time. I had a guide scope on my Cave 8" f/7 Lightweight Deluxe for a long time and used it when taking long exposures with a Pentax K1000 SLR film camera and the mount also had dual-axis slow motion motor control. The last time I overhauled that scope, I didn't put the guide scope back on because I didn't need it and thought it was more of a cosmetic addition than anything else. I have had good results now-a-days with a Canon T3i and 15-30 second exposures and a rough polaris alignment.
