primary light path would be a large enough flip mirror - guess I need a 2" light path (not the 1.25" models like the Orion one Bintel sell) - into a COMA corrector -> Canon DSLR

secondary light path would be a tube extender of roughly the same length as the COMA corrector -> eye piece with a helical focuser on the flip mirror to make the both Camera and eye piece's focus points parafocal.

The only models I common see that have helical focuses on one light path seem to have 1.25" eye piece connectors to the main OTA e.g.

I wonder that this would chop a DSLR's imaging chip.

Can anyone offer advise of what I am trying to achieve please?

Thanks, Matt
Hi Matt,

Have you looked at the Sliders from Van Slyke Instruments. Sounds like this may be what you are looking for. http://www.observatory.org/sliders.htm

There was a review in July 2002 S&T that explains their sliders.

Cheers Peter
