William Optics

 

The William Optics Flat7A is an apochromatic triplet 0.8x flattener/reducer with STM-coated Ohara lenses. The 44.4mm image circle (43.4mm with the Z126) makes it a perfect match for full-frame sensors.

The Flat7A features adjustable spacing for use with a range of cameras and imaging systems. The Flat7A includes an M48 filter thread which will hold any standard 2" mounted filter.

Compatible with William Optics FLT 120 (with adapter) FLT132, FLT156, GT102GT153, & Z126 telescopes which have an M92 x 1 thread. On the camera side there is an M48 x 0.75 male thread, which will accept any wide T-ring.

Note: As this is an adjustable flattener, you must adjust the distance for your specific telescope. See the Instructions tab above.
