This is the updated version of our Pegasus Astro FlatMaster 250L, our bigger, slimline, flatfield panel. It provides a uniform source of illumination for up to 10-inch telescopes and produces high-quality flat field frames for astrophotography and photometric captures.


Dimmable Panel

Unlike other panels in the market, the FlatMaster can adjust its brightness from 0 to 100%. Forget sheets of paper between your telescope and the panel. Remote control the brightness of your panel. Store the brightness per filter and immediately retrieve the value you need.

The Flatmaster 250L can go up to very high brightness levels so it can easily support short exposures (2-3 seconds at f/7) with 3nm narrowband imaging filters

Manual Button
The FlatMaster has a small push button that sets different gradual levels of brightness. In case you would like to manually operate the FlatMaster, no problem, just click the push button to control the brightness.
One Cable Operation

Only one cable (USB) is required to provide power and control of your flatpanel.

Unity Platform Support

Unity Platform allows you to set filter names and store / retrieve brightness levels of your FlatMaster panel
