[suma126 (Shane)]

i just received a astro tech reducer and flattener for gso 8 rc ota and try-ed it last night and all i got was egg shaped stars and was wondering has anyone Else got one with the same problem.

The corrector requires 75mm of spacing between the rear lens and the focal plane of the camera, so some spacers will be needed to make it work with a DSLR.What camera etc were you using?

Interested in how you get along with this, have been thinking of getting the Astrotech flattener.

Are you allowing for the 46.5mm from the front of the bayonet mount on the camera to the focal plane of your Nikon?
