The Pegasus Astro Indigo off axis guider (OAG) is a thin and solid designed OAG which can easily be bonded with our Indigo Filter Wheel. The OAG supports through holes (M2 and M3) in its body for direct connection with the 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.

The Pegasus Astro Indigo off axis guider features:

Thin Design

The 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 light weighted and solid piece of equipment. If the supplied camera adapter is also required to mount your camera, then the back focus will increase to 18mm.

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 Hole Pattern

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

Solid design for heavy load of imaging gear

The thickness is 10mm and is design is solid enough to support heavy imaging equipment. The clear aperture is 53.5mm

Indigo Filter Wheel Combination

The Indigo OAG can be directly mounted onto the Indigo Filter Wheel.
A combination of both products produces a 19mm + 14mm (33mm total) of backfocus optical distance.
