ZWO OAG Adapter features:

  • Lightweight and beautifully machined
  • 16.5mm thickness
  • Large prism: 8*8mm (actually, it's a mirror)
  • Allows the use of a guide camera in off axis position next to the main imaging camera without the need for a guide scope.
  • Flexible adaptation to your camera and telescope via  T2 (M42*0.75) and M48 threads
  • Fully compatible with all ZWO ASI cameras, but please contact us about which ZWO cameras we recommend for guiding. (The ASI174 chip is a bit too big for this mirror, so there will be strong vignetting in the guide image, therefore we'd recommend to use cameras with smaller chip for guiding.)
  • Good stability, stiff connection to the telescope

What's in the box (see above image):

  • OAG body(with 1.25″ holder and 5mm extender and M42 adapter)
  • M48 adapter for main imaging camera(in the box)
  • M48-M42 adapter for telescope and flat lens(in the box)
  • Hexagon wrench (Allen key)

How to use it:

1.   start with caculating the correct required distance for your imaging train. For example: you need to attach 21mm extender to ASI071 to reach 55mm back focus distance:17.5mm+21mm+16.5mm=55mm

2. Take off the guider prism part and attach OAG body to the telescope
