Alnitak Flat-Man L Large Flat Fielder

The Flat-Man L is the big brother of the Flat-Man, for telescopes in the 8-12.5" range. The Flat-Man L uses the same electroluminescent technology as our other products, and can either be manually placed on the vertical OTA or hung perpendicular (using one of the #6-32 cover screw holes) to the OTA’s park position for flat field imaging.

Our Windows XP software will light and control the brightness of the Flat-Man L. Comes with USB cable and power supply.

The Flat-Man L is an affordable means to achieve excellent flat fields for telescopes up to 12-1/2" diameter.
