Re: A question about a AP155 EDFS with the 2.7" focuser

OK, now I am hearing from the scope's owner that the 86.5 number is the spacing for the flatener - which I do not anticipate that we will need with a 4/3" sized detector (the same size as a 8300 CCD).  

How far back should I set the camera detector from the back of the focuser barrel to be able to have some reasonable in and out travel of the focuser?
