If a user’s OTA has a long focal length, and the environment is not ideal, there will often be fewer stars suitable for guiding to be found in the FOV. One way to improve the chance of finding a good guide star is to use a guide camera with a larger sensor. For example, guide cameras like the QHY5III174M or the QHY5III585C have a FOV that is 2-4 times larger than that of smaller cameras typically sold as guiders. This larger FOV naturally allows you to capture more stars, essentially solving the issue of no or few stars available to guide the image.\u003c\/p\u003e\n\u003cp\u003eIn order for a large-sensor guide camera to fully perform to its potential in an OAG, a prism large enough to allow illumination of the larger sensor is needed to avoid severe vignetting. The new OAGL Pro uses a new wider prism to better accommodate larger sensor guide cameras. The prism size of the standard QHYOAG series is about 8 x 8mm, while QHYOAGL Pro is 10 x 14mm.\u003c\/p\u003e\n\u003cp\u003eWhen the QHY5III174M is connected to the older version of QHYOAG, there is severe vignetting (Image 1, below). In contrast, connected to the OAG Pro in the same optical system, there’s only a small amount of darkening occurs at the edges, which won’t affect guiding at night (Image 2, below).\u003c\/p\u003e\n\u003cdiv class=\"tit\" id=\"a4\"\u003e\u003cstrong\u003eBrief User Guide\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv class=\"tit\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003eBefore using, please remove the protective film attached to the prism.\u003c\/p\u003e\n\u003cp\u003eThe OAG body has six holes with a diameter of 3mm, used for connecting with various adapter rings or the QHYCFW3 filter wheel.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.”\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications \u003c\/h3\u003e\n\u003ctable width=\"450\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"font-style: inherit; font-weight: inherit;\"\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\"\u003eModel\u003c\/td\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\"\u003eQHYOAGL Pro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"font-style: inherit; font-weight: inherit;\"\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\"\u003eTelescope Interface\u003c\/td\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\"\u003eM62\/0.75 or M54\/0.75 (combined with certain adapters)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"font-style: inherit; font-weight: inherit;\"\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\"\u003eFocal Length\u003c\/td\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\"\u003e12mm (excluding adapter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"font-style: inherit; font-weight: inherit;\"\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\"\u003eSuitable for CCD\/CMOS Size\u003c\/td\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\"\u003eFull Frame and Medium Frame CMOS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"font-style: inherit; font-weight: inherit;\"\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\" rowspan=\"2\"\u003eCompatible Filter Wheel\u003c\/td\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\" rowspan=\"2\"\u003eQHYCFW3XL, QHYCFW3L and QHYCFW3M (combined with certain adapters)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr style=\"font-style: inherit; font-weight: inherit;\"\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\"\u003eCompatible Guide Camera\u003c\/td\u003e\n\u003ctd style=\"font-style: inherit;\" width=\"225\"\u003eLarge-sensor guiding camera like QHY5III174M is recommended.
