Details

FC90 Flat Cap Imaging Diffuser fits 80-89mm tube OD or 63mm ERF Spun Aluminum mounting ring with polymer diffuser for taking flat field.

FlatCap is TEMPORARILY applied over the objective to acquire a "Flat Field" reference image which is then subtracted from live images taken after the FlatCap is removed.

FlatCap is sold by inside diameter of the mounting cap. Measure the outside diameter of the frontmost component of your telescope or ERF, and then round up to the next larger size. For example, a telescope with a 160mm front should use model FC170, and then optionally install the included felt pads for a secure fit.
