Our thin and solid design OAG can easily bond 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 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.

Description

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

Riley ★★★★★

I was worried about flexure ruining my subs, but this OAG mates perfectly with my filter wheel and the M3 through holes made attaching my camera rock solid. Definitely tightened up my stars across the whole frame.

Adam I. ★★★★★

The integrated through holes made attaching my camera a breeze — no more fiddling with adapters. Works perfectly with my filter wheel setup, and the whole assembly feels rock solid.

Leo ★★★★★

Finally a guider that actually mates perfectly with the filter wheel I already have—the thin body keeps my backfocus exactly where I need it. The integrated M2 and M3 holes made attaching my CMOS camera a breeze without extra adapters.
