I have a Mewlon 210 and would like to upgrade it with a Moonlite focuser. Does anyone have this upgrade who also uses a binoviewer? If so, do you have any issue bringing the scope to focus when using the BV?
I have a Denkmeier Power Switch that utilizes a 1.2x OCS that screws into the field end (before the diagonal) of the 2" AP MaxBright. I would think with the scope's moving-mirror focuser it wouldn't be too much of a problem to reach focus, but thought I'd check with the CN community first just to be sure.
Thanks for your time!
I think you will struggle to get to focus with the Mewlon if you install a Moonlite or any other focuser to it.
Even with my Zeiss binoviewer and Zeiss T2 prism I have to use a short visual back to get focus without a corrector. If you add a Moonlite you will have use a OCS or GPC that gains at least 75mm.
That would also mean that you would be working at an effect FL of about 4800mm+.....
I suggest that instead you include a non-rotation T2 focuser into the parts train. That will allow you to fine focus after coarse focusing with the primary mirror....
The Mewlon 210 has about 160mm of back focus available from the 2" visual back.
