You can get mounting rings that will fit each telescope. Most mounting rings will have a place on the top where you can bolt on a rail for to mount another telescope on top or just both the upper rings to the lower rings without rails. Theoretically, you could stack 5 or 6 telescopes on top of each other with mounting rings. I would guess OrionTelescopes would have rings to fit both telescopes. Look in the accessories category on the Orion website.

Hello!
I would remove the bottom dove tail from the Mak and replace that with a pair of hinged clam- shell type ring set, which have threaded hole on top. You can then either direct bolt a dove tail(Orion pt#07382) similar to what's on the bottom now (But longer)to the top and mount the ST80 via it's own hinged clam shell rings(Orion pt#07370) or go with guider rings,(Orion pt# 07381). I'm not sure what type of rail you would use to attach the whole setup to the mount but for me I have a CGE#94214, but I'm mounting the ST80 with an Orion helical guider on top to a CGEM. Hope this helps!

CS, Ralph

I'd mount a Finder Shoe on the 80mm and use the Mak's Finder Base.

If the idea is to be able to see a wider view at an instant while using the Mak, sounds great to me.

That said, I went and bought a NexStar SLT mount for my ST80.  I often set it up right next to my own Apex 127, which rides in a NexStar SE mount.

The Apex works far better with a wide field 2" eyepiece than I expected it to, however, so there are nights that I skip the ST80.  If you haven't tried that yet, it's worth it.
