Lightweight and beautifully machined. 16.5mm thickness. Large prism: 8*8mm (actually, it's a mirror). Allows the use of a guide camera in off axis position next to the main imaging camera without the need for a guide scope.
Using this OAG and a Baader T ring, you can guide any DSLR camera with no additional extensions of rings, or "Off Axis" by using a reticle eyepiece or LVI Smartguiders.
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.
As a complement to the EFW2 filter wheel, we developed an Off-Axis Guider. The Atik OAG features a moving prism which allows selecting the best quality stars of your corrected field of view
The new OAG-L has a large prism size of 12*12mm, far bigger than M68 OAG. The bigger clear aperture brings wider field of view in guiding. It is easy to use, and suitable for users who are interested in long focal length photography.
The Off-Axis Guider is an essential astroimaging accessory for long focal length telescopes that require the most accurate guiding possible. The Celestron Off-Axis Guider uses a prism to intercept a small portion of the telescope’s focal plane (outside the field of view of the main imaging camera) to locate a guide star.
