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.
