Pegasus Astro's Indigo OAG, a thin and solid design, can easily bond with the 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 of having an OAG is that it uses the same optical path as your primary imaging camera. This avoids any issue with differential flexure that can occur when using a separate guide scope on top of your main telescope.
Thin Design
Indigo OAG has a very thin design. Its back focus is 10mm + 4mm of the telescope adapter. 14mm in total. OAG is CNC made of airplane 6061 aluminum alloy which ensures a lightweight 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.
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.
Package Includes:
a M54F threaded adapter for telescope connection. (adds a thickness of 4mm)
a M48F threaded adapter for camera connection. (adds a thickness of 4mm)
You can use both adapters to create a standalone OAG.
Helical Focuser
A pre-installed helical focuser is included, providing precise focusing capabilities and seamless compatibility with 1.25” guiding cameras commonly available in the market.
Indigo Filter Wheel Combination
The Indigo OAG can be directly mounted onto the Indigo Filter Wheel.
A combination of both products sums 19mm + 14mm (33mm total) of back-focus optical distance.
