Hi Jennifer -

I have the Moonlite 2.5” focuser with the Moonlite to ES adapter for the reducer.  I’m using the ES adapter with 45 mm of backfocus as I’m using a Canon DSLR.  It’s a camera from CentralDS that’s starts out life as a T3i and after modification ends up in a sealed aluminum housing with a cooler directly behind the sensor.

Very nice Steve.  Well done.  Is the 0.7x reducer your using the 3” ES version?  If so, what is the spacing between the camera sensor and reducer.  Are you using a filter?  Did that affect your spacing?  I ask because I have read several posts on CN that state if filters are used then additional spacing is required which is 1/3 the thickness of the filter being used.
