The documentation shows a back focus of 72.8 mm but does not show where the original focus point is.

Does someone have this information?

Hi Bill

 

The distance between original focus and corrector is 56 mm outwards.

The distance between corrector and camera sensor (backfocus) is 72.8 mm.

 

The attached image shows the Baader MPCC with a DSLR on the left side and the ASA 2" Quattro corrector on the right side

 

Best Regards

Thomas

Thomas,

 

In the image where is the top of the ASA 2" Quattro?  Is it just above the top set of screws or is it threaded into the bottom of the extension?
