Approximately 2hrs 10minutes of 300s exposures through a Celestron 9,25 with a f6,3 reducer/flattener.
Camera: Atik 383L+ color camera.
Mount: eq8
Guiding: loadstar through a William Optics 90 mm.
Question: what is the proper distance from the camera chip to the reducer for Celestron's f6,3 reducer? I've seen numbers ranging fro 85mm to 105mm.
Thanks for looking.
