QHYCCD OAG M Pro (QHYOAG-MPRO)

QHYCCD OAG M Pro

Greatly improve your guiding accuracy and image stability with the QHY OAG-M Pro! When it comes to guiding, the more stars available to choose from, the better. Introduce your OTA’s large aperture to your guide camera and greatly increase the number of guide stars accessible. Eliminating the problem of vignetting that OAGs with smaller prism sizes are known to produce, the QHY OAG-M Pro offers a large prism size for guide cameras with larger sensors, utilizing your guide camera’s full light gathering ability!

Increased Guiding Accuracy

By eliminating the need for a second guide scope, the QHY OAG-M Pro allows your guide camera to have the same field of view as your imaging camera, reducing differential flexure and utilizing your telescope’s larger aperture. This increased light gathering power allows for more guide stars to be resolved for an improvement in guiding performance and image stabilization. This QHY OAG-M Pro has a durable and robust design, securing your guide camera in place and offering accurate alignment with your imaging camera.

Ideal for Large Sensor Guide Cameras

Using guide cameras with large sensors allows for a greater field of view, in turn increasing the number of guide stars accessible. With this in mind, the OAG installed must have a prism size that can accommodate for larger sensors in order to maximize the improved light gathering ability of these types of guide cameras. As opposed to the standard 8x8mm QHY OAG series that resulted in serious vignetting while using large sensor guide cameras, the new QHY OAG-M Pro offers a substantial prism size of 10x14mm, allowing your camera to utilize its full light gathering power and greatly increase the number of guide stars available!

Before using, please remove the protective film attached to the prism.

The OAG body has six holes with a diameter of 3mm, used for connecting with various adapter rings or the QHYCFW3 filter wheel.

The OAG includes a prism position adjustment locking knob located on the side of the body. When this knob is loosened, the position of the prism can be adjusted. Adjust the prism’s position carefully to ensure it doesn’t obstruct the chip. If you find any obstruction in the corresponding position of the captured image, move the prism further away from the chip.

The OAG features a helical focusing seat, allowing for fine adjustments to the camera’s focal plane. On the focusing seat, there’s a focal plane position locking knob. When adjusting the focus, please release this knob. Once the focal length is adjusted, lock this knob. Do not forcibly rotate the focusing ring when it’s locked, to prevent damage to the internal structure. Once locked, you’ll notice that the focusing ring can still move slightly left or right. This is normal, and at this point, the camera is locked, and the focus won’t change.

The OAG can be used in conjunction with a guiding camera. It’s important to ensure that the distance from the prism’s surface to the guiding camera is equal to the distance between the prism’s surface and the imaging CCD. If the guiding camera is still not in focus at its limit distance, you can remove the front end of the guiding camera to further shorten the distance.”
