Alnitak Flat-Man XL Flat Fielder

The Flat-Man XL is our stationary observatory model electroluminescent panel that will accommodate telescopes up to 30" in diameter. This product is revolutionizing the way flats are acquired at observatories around the world. They are used by both professionals and amateurs on several continents.

For the serious observer with large observatory mounted telescopes, there is now a way to guarantee excellent flats on demand. Our testing shows that the Flat-Man XL provides an exceptionally evenly illuminated field when imaged by a camera mounted to a telescope focused at infinity.
