Product description

The DayStar FlatCap is a Gaussian diffuser that is temporarily installed over the front of your telescope when taking flat field reference images. By strongly blurring the Sun, the only details you will see in the reference image are from defects in your imaging train that can be removed in software.

Warning! The Daystar FlatCap is NOT a solar filter.
