This super thin and solid Indigo Off-Axis-Guider can attach directly to your camera or 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 on the market.
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 and can dramatically improve your autoguiding.
A helical focuser addon also provides precise focusing for your guidecamera and and is seamlessly compatibile with 1.25” guiding cameras commonly available on the market.
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.
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.
