I have a new 10" LX850 which I am using for AP work. It is configured for two setups - Solar System and DSO (where I use a Lepus reducer). I am hoping there are some owners out there that have gone down this path and can advise me on my setup. Unfortunately Meade would not provide a reference implementation for any setup apart from the back focus number below.
Meade advised that the back focus for the LX850 is 4.57".
My question is with Solar System imaging setup (1) below and whether I should be putting in extensions into the imaging train and where? Do I need to pad out 4.57" to the Powermate first lens or something else?
Setup 1 - 2" rear cell SCT adapter -> M48 T-adapter -> 48mm Extensions (???) -> TV Powermate w M42 T-adapter -> 42mm extensions(???) -> CCD
I expect this setup below is straight forward:-
Setup 2 - 2" rear cell SCT adapter -> M48 T-adapter -> 48mm Extensions -> M48-M42 (F/M) -> CCD (length to CCD sensor from Meade rear cell flange is 4.57")
Any advise appreciated.
