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.

"The Flat-Man XL's are outstanding and are really a life saver for us to get customers their flats in a timely manner"

For today's millimagnitude exoplanet photometry, or for the extensive stretching that is being done with aesthetic astronomical imaging, image flatness is of utmost importance. Generating good flats has been a challenge until now.

The Flat-Man XL is completely controllable from a USB interface using our Windows controller software and is also compatible with CCDAutopilot, as can be seen here.
