Does anyone know if this will mount directly to the Megrez, or will I need to go down the path of tube rings?

Thanks

I'd wait and get the new deluxe version - it at least has a helical focuser. The originals - like the ones Bintel sell, are a royal PITA to get good focus with as you are moving the objective and the camera in and out to try to make a good focus, which then all goes to pot the minute you tighten up the objective (I always left the objective not secured, which is not a good thing, but at least it held focus!).

In short, I disliked the Orion mini guider a LOT. I sold the insensitive SSAG, but kept the scope as I can unscrew the rear adapter and mount it to a Takahashi finder scope, which makes for a 1000000000000% better rig.

Your results may vary, but there was ALWAYS flexure with this system, not to mention the focus issues.

BUT, it works, though not the best. My imaging has improved 100% since using a long focal length guidescope (self made from an old Meade refractor) with solid rings (not guide scope rings) and a Lodestar.
