The Flip-Flat
The Flip-Flat
Alnitak Astrosystems flagship product, the Flip-Flat, is a robotic lenscap and flat field illumination source for mid-size refractors.
With dozens of Flip-Flats already in the field being used by satisfied customers, we're confident that our product is meeting the needs of discriminating astro-imagers around the world.
The Flip-Flat employs advanced electroluminescent panel technology to provide a uniform source of illumination for the production of high quality flat field frames necessary for serious astroimaging and photometric work. With the Flip-Flat, on-demand flat fields with uniformity errors less than 1% are now possible.
In addition to providing excellent flat fields, the Flip-Flat protects the objective lens of the telescope from dust that typically plagues remote installations where the user cannot manually replace the lenscap after an imaging session.
A report of our testing procedure and results can be found here.
The Flip-Flat can be mounted quickly to the front of any telescope tube (or rigid dewshield) with an outside diameter of 4-7.625". It is easily removable for transport and storage.
