Product information


The Pegasus Indigo OAG is our thin and solid design OAG which can easily bonded with our Indigo Filter Wheel. The OAG supports through holes (M2 and M3) in its body for direct connection with latest CMOS cameras and other Filter Wheels.

The main advantage having an OAG is that it used the same optical path with your main imaging camera. This avoids any issue with differential flexure that can occur when using a separate guidescope on top of your main telescope.

Thin Design
Indigo OAG has a very thin design. Its backfocus is 10mm + 4mm of the telescope adapter. 14mm in total. OAG is CNC made of airplane 6061 aluminium alloy which ensures a lightweighted and solid piece of equipment.

Adjustable prism
The prism height can be easily adjusted to allow better illumination of the field of view of the guiding camera. If your imaging camera sensor is large, the prism can be moved (and secured with set screws) upwards to disallow blockage of the sensor’s optical path.

Large mirror
A 12×8 mm fully multicoated & anti-reflection mirror offers high illumination to your guiding camera. Stars are round and bright across the OAG ‘s field.

Large Size
Indigo OAG supports the 62mm through hole pattern for direct connection with latest CMOS cameras and Filter Wheels.

Guiding camera connection is a 1.25” barrel.

Orientation of image train framing can be achieved by the 3 screws that allow telescope adapter to slide inside the slots
