The William Optics longer adapter for FLAT68III or FLAT7A will allow you to use the FLAT68III flattener on a Fluorostar 91 refractor. It ends with a male M48 thread for connection to the imaging train.

This adapter has a total length of 45mm. This is longer than the 30mm version supplied with the FLAT6AIII flattener.

To use the adapter, remove the short version that was supplied with the FLAT68III flattener. Next replace it with this longer version. If you have a Fluorostar 91 refractor, set the flattener at 5mm.

 

  • Male thread: M48x0.75
  • Female Thread: M80x0.75
  • Length 45mm

To use this adapter, simply unscrew the original end adapter that terminates in the M48 male thread on the flattener and replace it with this longer adapter.

Correct back focus setting specifications:

  • For P-FLAT68III with FLT91 telescope: 5mm
  • For P-FLAT68III with WIFD GT81 telescope:10.9mm
  • For Flat7A with FLT120 telescope: 1.4mm
