I have a C-8 f10. Using my old 35 mm SLR (film) with a T-ring adapter, the full moon fit on the film frame with a little extra top and bottom. When I use my 35mm SLR digital (Canon Rebel) in the same configuration , the moon is oversized and is cut off at top and bottom. (Am I jealous of Dave's prime focus lunar photos - yes - damn you Dave :)) What is happening? Can it be fixed?
That is because your film (sensor) is 25 x 35 mm, the sensor (chip) is about 15 x 22.5. Image scale doesn't change. You can't squeeze the larger image into a smaller sensor. On Sat, Apr 4, 2015 at 6:39 PM, Joan Carman <jcarman6@q.com> wrote:

The telecompressor screws onto the back of the C-8. The T-adapter then screws onto the tele-compressor, the T-ring screws onto the back of the T-adapter and the camera attaches to the T-ring. It can also be used with eyepieces. To do that screw the tele-compressor onto the back of the telescope and screw the visual back (eyepiece holder) onto the tele-compressor. patrick On 05 Apr 2015, at 01:14, Joan Carman <jcarman6@q.com> wrote:
