For those on a budget who don’t need the robotic features of the Flip-Flat, the Flat-Man is an excellent choice. Employing the same EL lamp technology as in the Flip-Flat and powered by a single USB cable, the Flat-Man is simple to use.  The Flat-Man is manually placed on the vertically oriented OTA and the lamp brightness levels can be  controlled via the attached PC.

OTA's up to 6-inch (155mm) are supported with the Flat-Man.  For larger scopes, the Flat-Man L is available for manual or remote flat field calibrations.  

For the imager who doesn't need the robotic capability of the Flip-Flat, the Flat-Man is now available. The Flat-Man uses the same technology as the Flip-Flat, but is manually placed on the OTA for flat field imaging. The only power you need is a USB cable, and our Windows XP software will light and control the brightness of the Flat-Man. Simply rotate your telescope until the dewshield is pointed straight up and place the Flat-Man centered on your scope.

The Flat-Man is an affordable means to achieve excellent flat fields. For dewshield OD's up to 7.625".
