William Optics Adjustable 0.8x Reducer/Flattener for Z61

William Optic’s 0.8x Reducer/Field Flattener is a great tool to use when you want to improve image quality by being able to adjust spacing without the need for extension tubes.

This particular 0.8x field flattener and reducer is designed specifically for the William Optics Zenithstar 61 refracting OTA. Additionally, it is manufactured with full frame, chip-size DSLR cameras in mind. The types of CCD and CMOS cameras that can be used with this tool are as follows:

  • M4/3
  • Sony α
  • Nikon
  • Pentax
  • Canon
  • FUJI

Users can also attach a filter wheel to the cameras, and the Adjustable 0.8x reducer will still function like normal.

The flattener’s backfocus is 56 mm and the adjustment distance for DSLR and mirrorless cameras is 1 mm.

On the camera rotator side, there is a M54 thread. The rest of the body is equipped with M48 threads on the telescope side and the filter side. To install M48 threaded filters onto the flattener/reducer, users need to remove the rotator by twisting it off, then the filter (not installed) can be installed, and the rotator can be placed back on.

To install the flattener, users must remove the eyepiece adapter and connect the accessory to the M54 telescope thread.
