Photographic field flattener for our f6 refractors:

This field flattener is designed to work with our 480 mm focal length optical systems. This includes our 80mm f-6 telescopes. The flattener plugs into the focuser and a DSLR camera mounts to it using a standard photographic t-ring. CCD cameras will also work with this flattener but a threaded extension may be required.

The Importance of proper spacing: The photographic field flattener must be placed at a precise distance from the camera’s internal ccd sensor. If the spacing is incorrect, the performance will be compromised. Our stock flatteners are made to work with DSLR cameras. The distance from the t-ring to the internal ccd sensor on a DSLR camera is about 55 mm. This distance from the thread on the front of the camera to the sensor is also known as its “backfocus.”
