Sorry David, jsut saw this and would have responded earlier myself.

[h0ughy]

no worries Paul, my next question is are there any radius blocks needed to fit the bar onto a c8 OTA?

[gbeal]

Given a round tube front and rear, the answer would be yes.
I have made them in the past though, just a rounded section, with the flat surface to mate to the rail. Not rocket science.

David; Losmandy make a bar called a DC8 bar which comes with mounting blocks. They are a perfect fit for the 8" OTA.

Paul I bought a Celestron nexstar SE mount - because i have a lunt i wish to use with it and i also have a C8 with losmandy dplate and a ADM on the top.

i found a vixen style bar in my junk i have but realised that it wouldn't fit right length but not the exact holes to line up- i was missing something (maybe normality).

[Paul Haese]

So you are looking to fit the Lunt on top of the C8 while it is mounted to the SE mount? The vixen bar would not be that great anyway. I have the clam shell of the Solarmax fixed directly to a small losmandy plate, so I am think you would need a D plate instead of the vixen plate.

[h0ughy]

no just the lunt by itself

[Paul Haese]

Well can you screw and or tap two holes to hold the clam shell in place on the vixen bar. I take it that the vixen bar is the only one that will fit that mount?
