Product Details

  • The Flip-Flat Fielder from Alnitak and Optec (size 6-Inch to 7-5/8-Inch) is a robotic lens cap and flat-field illumination source for small to medium size refractors.

    This particular model is best suited for OTA's between 6-inch and 7-5/8-inch. It acts as a dust protection device and provides flat-field illumination in a convenient and compact package.

    Alnitak Astrosystems' flagship product, the Flip-Flat, is a robotic lens-cap and flat field illumination source for small to medium size refractors.

    With hundreds of Flip-Flats already in the field being used by satisfied customers, we’re confident that our product continues to meet the needs of discriminating astroimagers around the world.

    The Flip-Flat employs advanced electroluminescent lamp 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-percent 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 lens-cap after an imaging session. The Flip-Flat is easily mounted to the front of any telescope tube (or rigid dewshield) with an OTA outside diameter between 4-inch (100 mm) and 8-1/8-inch (206 mm). The Flip-Flat is attached to the telescope OTA with industrial nylon zip straps and easily removable for transport and storage.

    A simple Windows interface provides the ability to open and close the Flip-Flat and turn on the light source. The intensity of the light can be adjusted to one of 255 levels.

    IMPORTANT: Note that the diameter of the fully illuminated lamp for each of the Flip-Flat models is 6.7-inch or 170 mm, regardless of the model purchased. To accommodate the smaller 4-inch to 6-inch OTAs, we add a spacer to the mounting bracket which better centers the lamp over the OTA. For the larger OTA, the bracket is machined down and an over-sized ring is added to block any stray light from interfering with the flat lamp. 

    The #OP-19051 Flip-Flat package includes the controller, motor arm, OTA bracket to center the lamp over OTA dew shields measuring 6-inch to 7-5/8-inches in diameter, a pair of industrial zip straps, USB cable, and software. Fully illuminated lamp is 6.7-inches (170 mm) in diameter.

    The Item was shipped expeditiously, it works as advertised, the installation is straight forward, very easy to install, the interface is very user friendly, intuitive and easy to use, I just need to try the Ascom drivers to see how it works with SGP, is almost all plastic made, but in a very good quality, the flat panel works flawlessly , what amazed me, is that it works on non powered USB ports, overall I am really happy with this gadget, I will definitely buy another two for my 80mm refractor and guide-scope, and later another one for my 10”Newtonian, if you want to control your observatory remotely, this is a must have accessory
