Diagonals

Hutech 1-1/4" Prism Diagonal (DP36.4)

This low profile prism diagonal comes with a 36.4mm front thread which matches Vixen or Takahashi scopes as well as Borg scopes via Borg parts 7522 or 7364. Back focus required by this diagonal is minimized due to the 36.4mm thread interface, or it can be mated to Borg part 7316 (1-1/4" nosepiece) for configuration as a standard diagonal.

The diagonal is sold alone, or mated with Borg 4317 or 7315 mini-helical focusers.

Matsumoto Erect Image Mirror Diagonal (EMS-S)

This is a unique mirror diagonal which utilizes two mirrors to create a non-inverted image at the output. 120mm of backfocus is required. The diagonal interfaces with a 2" sleeve on the telescope end, and 1-1/4" eyepieces on the back end. 48mm filters are accomodated under the black eyepiece holder section of the diagonal, and a 36.4mm thread allows an accessory such as a Borg mini helical focuser to be added at the eyepiece end.
