ZWO OAG-L Off Axis Guider

• NEW ZWO OAG-L Off Axis Guider with larger 12mm x 12mm prism.

  This new ZWO OAG-L is for use with ZWO APS-C (ASI2600) or full frame (ASI6200/2400) cameras and (only) EFW 36mm V2,  EFW 2" (5x or 7x slot model) filter wheels, or the ZWO M54 Adaptor, with no EFW.  

  Provides a wider clear aperture than the previous model. 

  Easy to use and particularly well suited to longer focal length telescopes or telescopes with moving mirror focussing systems. 

  Features

  • Lightweight and exquisite
  • 17.5mm thickness.
  • Prism size: 12x12mm.
  • The effective light-passing aperture is 11.7mm*8.3mm.
  • Packaged with an M48 sensor tilt plate (5mm)
  • It also works with ASI Mini cameras ASI174MM Mini, ASI290MM Mini and ASI120MM Mini.
  • The large clear aperture supports full-frame cameras without vignetting.

  NOTES:

  1. Considering the large prism size, we don’t recommend you use the OAG-L with telescopes with rear screw thread smaller than M48.
  2. The significant differences between OAG-L and M68 OAG are the prism size and the threads. The OAG-L design removed the inner threads so you can directly use the screws to connect it to other equipment. 
  3. If the thread of your telescope side is M48, then you don’t need to remove the M48 sensor tilt plate coming with OAG-L.
