ZWO-OAG Off Axis Guider
NEW from ZWO Thin Off Axis Guider that allows you to Autoguide in SCTs and Refractors whilst only adding 16.5mm to the optical path.
Features a precision 8mm x 8mm prism, it comes complete with M48 and T2 adapters to the scope and M42 and M48 adapters to camera to keep back focus to a minimum, a 5mm spacer for guide cameras where the back focus is only 12.5mm.
Compatible with all ZWO ASI cameras.
A must for Cassegrains,and Refractors No guide scope - No differential flexure between Guide scope and main telescope.
Connection diagram
The Celestron 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. Any movement seen by the guide star will be the exact same movement seen by the imaging camera. Guiding this way will correct for tracking errors, as well as opto-mechanical errors or flexure. The result: better astroimages with pinpoint round stars.
Off Axis Guiders have been around for a long time, but typically pose three main challenges:
Finding a guide star from the far edges of the telescope’s focal plane can be difficult, considering the small field of view and sometimes less-than-ideal illumination.
Getting both imaging camera and autoguider to reach focus with one another is time consuming and sometimes requires experimentation.
Additional spacers and adapters are usually required for your particular camera, telescope, and autoguider, which adds to cost and complexity.
The Celestron Off Axis Guider addresses these challenges by:
Providing a large 12.5mm prism that can be adjusted to move closer to the center of the telescope’s focal plane, depending on the size of the imaging camera. This results in brighter guide stars, with the help of the large prism to fully illuminate the autoguider sensor.
Featuring a high-quality, fixed-orientation Helical focuser. This provides extremely smooth and accurate focus of the autoguider without changing (or twisting) the autoguider camera orientation.
Including all the needed spacers and adapters are included for most common imaging configurations, including DSLR cameras, Nightscape CCD cameras, and more. The following adapters are included: SCT/EdgeHD, female M48, female M42 (T-thread), male M48, male M42 (T-thread), 3 T-thread spacers

New Improved from ZWO-OAG-L ZWO-OAG-L is the latest iteration of M68 OAG with a larger prism size of 12mm x 12mm. 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. To take the most advantage of it, we recommend you to match it with large format guiding cameras. Features: 1. Lightweight and exquisite, 17.5mm thickness. 2. Prism size: 12mm x 12mm. 3. The effective light-passing aperture is 11.7mm x 8.3mm. 4. Can be used to connect the main camera and guide camera simultaneously. No guide telescope required. 5. Packaged with an M48 sensor tilt plate (5mm). Operating Guide: 1. For guiding, OAG-L can only work with ASI Mini cameras like ASI174MM Mini, ASI290MM Mini and ASI120MM Mini. 2. Considering the large prism size, we don’t recommend you use OAG-L with telescopes whose clear aperture is smaller than M48. 3. Yet it is recommended to use with 2” EFW or 7x36mm EFW, and with APS-C cameras (ASI2600) or full frame cameras (ASI6200/2400). The large clear aperture supports full frame cameras without vignetting. 4. The major differences between ZWO-OAG-L and M68 OAG are about the prism size and the threads. ZWO-OAG-L removed the inner threads so you can directly use the screws to connect it to other equipment. 5. If the thread of your telescope side is M48, then you don’t need to remove the M48 sensor tilt plate coming with ZWO-OAG-L. On the contrary, you need to remove it and use some other sensor tilt plate at the corresponding thread of your telescope. The pictures below show how to remove the sensor tilt plate: OAG-L Mechanical Drawing OAG-L & OAG-L-68 Mechanical Drawing Connection Guide: Please Note: While adding ZWO-OAG-L into your optical train, please make sure the prism won’t block the camera sensor. You can use the guiding screw to adjust the guiding camera’s focus length. Please make sure the distance from the prism to the main camera and to the guide camera are the same. To ensure the result, it is better to do this in the daytime for the adjustment will be very difficult at night.

QHYCCD has designed a dedicated Off-Axis Guider (OAG) for the miniCAM8, featuring a large 14×10mm prism. The oversized prism maximizes light throughput to the guide camera, enabling higher guiding precision. It comes with a standard M48 telescope interface for easy connection and maintains a 55mm back focal distance for broad compatibility with imaging setups.
Stable and Strong
High Parallelism
Direct connection to the camera with six screws ensures connection accuracy and parallelism, providing a reliable mechanical connection for your photography
Precision Connection
No Deflection
The main purpose of the QHY OAG-S is to use the same optical path as the main camera. This avoids the problem of differential deflection that can occur when using a separate optical system for guiding. In the case of the OAG, a part of the image is picked-off from the edge of the imaging circle which does not block the main CCD. This method provides more accurate guiding and sharper images.
Multiple Adapters
Flexible Combinations
In addition to the connection with the A-series cameras, you can also use the various standard or optional accessories provided by QHYCCD to achieve complex and adaptable connections, including the use of the QHY OAG-S as a stand alone unit, connection to QHY filter wheels, etc.
Stable and Strong
Precise Easy Focusing
The QHYOAG includes a precision 1.25-inch helical focuser that accepts our QHY5II and QHY5III cameras. The focusing process is comfortable. After focusing, you can lock the focus mechanism with thumbscrews.

Produce a larger area of illumination for your 9.25”, 11” or 14” Schmidt-Cassegrain or EdgeHD telescope by using the this adapter. When this adapter is paired with our Off-Axis Guider, these two imaging accessories allow you to use the full image circle in our larger scopes. This configuration is especially helpful to owners of larger format cameras, such as the Canon 5D or 6D, since their full frame can take advantage of the more substantial area of illumination produced by larger optical tubes.
What’s New!
The Large SCT & EdgeHD Adapter V2 for Off-Axis Guider has a longer optical length—38mm. The adapter’s longer length provides DSLR cameras back-focus spacing for Schmidt-Cassegrain and EdgeHD optical tubes in conjunction with the Off-Axis Guider without the need for extra adapters or spacers.
Body
The Large SCT & EdgeHD Adapter V2 for Off-Axis Guider is machined aluminum black anodized. The internal surfaces are sandblasted to help prevent glare and provide the highest contrast. The adapter has a knurled surface providing a great gripping surface for threading and unthreading.
