Optec Alnitak Flat-Man L CCD Calibration Panel - 8" to 12.5" OD

The Calibration Panel -Optec Alnitak Flat-Man L is for 8-inch to 12.5-inch OTAs: The Flat-Man L is the big brother of the Flat-Man, for telescopes in the 8-inch to 12.5-inch range. The Flat-Man L uses the same electroluminescent technology, 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 park position for flat field imaging. 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.

Ask a Question
  • I have a 14" Meade. Could this be used with it??

    Unfortunately, the flat panel diameter needs to be at least as large as the optical diameter, so this panel will not work for a 14" scope. We have a couple options for larger panels, so please contact us if you have questions.

  • Will this work with Windows 7 and USB 3.0?

    Yes, Optec says that there is no issue using a USB 3.0 connection and Windows 7 with the Alinitak Flat Man panels.

  • Is the software compatible with Windows 7 64 bit?

    Yes, both the Optec/Alnitak software and the ASCOM driver will work on Windows 7 64 bit.
