3.5" Prime Focus Field Flattener for 130GTX or prior 130EDFGT upgraded to 3.5" Focuser (13035FF)
Brand : Astro-Physics
The new 3.5” Field Flattener for the 130 Starfire GTX is a redesigned housing that utilizes the superb optics of the 67PF562. It provides pin point stars to the very corners of your CCD or DSLR sensor. The 130 GTX images at f/6.7 with the Flattener. It accommodates today’s largest sensors (even the KAF-50100).
Conveniently, it uses the same camera adapters as the Quad TCC (and those of the flatteners and TCCs of the 160 and 175 Starfires).
The backfocus spacing from the rear flange is:
With Backfocus Spacer - 80.8 mm +/- 2.5 mm
Without Backfocus Spacer - 102.9 mm +/- 2.5 mm
