Selling a mint condition Tak TOA 645 Flattener 0.99X for TOA-130 for $525
Being designed specifically for the TOA-130NFB, RMS spot diameters of 1 micron on-axis are achieved. At a 30 mm diameter image circle, the RMS spot diameter is 2 microns, and at 43 mm it is 3 microns. Even out to the full diameter of 60 mm, the RMS spot diameter is 5 microns. This works great for a full frame sensor.
For the TOA-130N with the included adapter ring (L), the flattener has a male M72 facing the telescope and a female M54 facing the camera. The metal back distance from the M54 thread is 56.2 mm. If you remove the adapter ring (L), the camera can interface with a female M72 thread with a metal back distance of 83.7 mm.
