Greetings,

I have a Celestron EdgeHD 9.25 and a 115 mm refractor (and a WO Z61). I have a dome on the way and I was told that the NexDome 2.2 has an aperture of 61 cm and it probably would not cope with a side by side solution for the two scopes given the diameter of the EdgeHD.

So the suggested solution is to put the refractor on top of the reflector. I have a Losmandy plate designed for the EdgeHD on top of the scope. It is held there with three small screws that screw into the EdgeHD. I am concerned that those three little screws and whatever is inside the EdgeHD that the screws screw into can cope with about 12 kg (minimum) of the refractor sitting on top of it.

I have an EQ8-R so payload capacity is not an issue. Has anyone tried doing that with a reasonably heavy refractor on top of the reflector. If I get carried away, I am considering putting the WO Z61 on top of the refractor. The pics I have seen have small refractors sitting on top but their weight wouldn't be anywhere near a min of 12 kg. TIA..

I know you can get bespoke parallax rings for the EdgeHD for a considerable cost that are made overseas.
