Hi paul,
The focal reducer is incorporated with a 1.25" diagonal (called a rich field adapter for SCT telescopes) . The unit was supposed to be F6.3 for visual use .I'm using it with a G star-ex for the pic shown. I found that by withdrawing the camera from the diagonal and refocusing i gained more and more reduction.
I believe i can probably get slightly more by moving it a little further out. Hence my request in the wanted adds for a broken barlow lens to gain me a bit more distance.I know from experiment that too far and the image changes into the black of the secondary obstruction.So thats the setup.
regards philip
