Hey folks, I want to try my SBIG on the WOGT81 with it's integral five element Field flattener- thing is it came with a DSLR adaptor but I want to know the correct spacing for the CCD
Any one have any idea?
I cannot see any info on the WO website.
Cheers
Graham
What brand camera is the supplied adaptor for?
Assuming it is for Canon, the flange-focal distance for Canon EF mount is 44mm, so adding the thickness of the WO adaptor should give you the back focus distance.
