Hello, i'm finally getting my ES 127ED back from ES and need suggestions on how to mouny my ST80 'guidescope' on the 127ED... the "handle" that comes with the 127 doesn't look wide enough or long enough to offer a good sturdy hold... trying to minimize flexure... Thanks. 

 

PS: This might be the wrong forum.. please move it if it is..

Moving this to refractors for a better fit.

Here is how I have mine, this is just a fit test setup. I have a few more parts to fabricate and replace but it gives you the idea and should avoid flexture. The guide scope is a WO 66mm Zenith Star. It's sitting on a Stellarvue 130mm.

Hello.. fabricate?  So you make your own parts?  I don't have access to do that.  Thanks for the advice.

Yes, these are test parts I've made and will market at some point. All the ADM and William Optics parts will go away soon. I make and sell custom stainless counterweights only now. Losmandy has a mount system of a similar configuration on the market.

This is how I mounted my ST80 to my FLT98. I added a vixen dovetail rail to the top of the FLT98. Then I got a couple of Losmandy DVA adapters and bolted them to the ST80 rings.

This is how I mounted my ST80 to my FLT98.

The focuser on the ST80 is nothing special, and your setup looks like the guidecam might flop a little.  But you have a fairly short FL main scope.

 

I mounted my ST80 on my EdgeHD-8 (2032mm, 1421mm FL) with the Losmandy 108/66 ring set because at long FLs I don't want any wobble.
