Optec has partnered with Chris White of Overcast Observatory to re-design the Flip-Flat electroluminescent calibration panel mechanical design. The new Alnitak Flip-Flat 270 design allows a full 270-degree rotation of the flat field lamp panel to rest against the side of the telescope OTA tube.

Available in two sizes the Flip-Flat 270 (stk# 19053) works with OTA dew shields up to 7-5/8" (194mm) while the Flip-Flat 270+ (stk# 19054) will cover an 8-1/8" (206mm) dew shield. Both include the time tested inverter electronics and 167mm EL lamp of the Gen2 Alnitak Flip-Flat.

The same mechanical design can be ordered in the Flip-Mask or Remote Dust Cover variants. In addition,

Overcast Observatory can design custom 3D printed mounting rings to match most any telescope tube diameter. This replaces the industrial zip ties included with every Flip-Flat sold through Optec.
