New, dedicated 2" flattener by William Optics optimized for use with their Z61 Apo telescopes.

On the telescope side, this flattener has a male M54 thread for direct connection to the focuser drawtube (this requires you to unscrew the 2" eyepiece holder ring to expose the M54 female thread inside the drawtube).

On the camera side, the flattener has a male M48x0.75 thread. You can use your Canon or Nikon DSLR directly with the use of an optional M48 camera-specific T-ring (sold separately).

Please note that this cannot be used with the smaller 42mm T rings.

True 1:1 flattener with no reduction. Weight 227gram.
