The QHY Camera Tilter Plate makes sensor alignment easier than ever. This adapter can replace the original front end of your camera. There is no added optical thickness, allowing you to maintain the original imaging train configuration. With a rear adjustment design, even after installing the filter wheel, it can be easily adjusted and is suitable for most astronomers using the combo of mono camera+ filter wheel. It provides six sets of adjustment points. You can choose either a three-point adjustment (equilateral triangle arrangement) or a four-point adjustment (rectangle arrangement). Compatible cameras: QHY600PH-SBFL QHY268M all versions QHY268C（short back focal length version after 2022） PS: The adapter can work with QHY533 in theory, but this camera with a small sensor is used mostly by beginners, it is not recommended to use the adapter with it. no added optical thickness This tilt adjustment adapter is simple to install. Use a screwdriver to remove the original front end of the camera and replace it with the tilt adjustment adapter. Note that removing the default front end also means that it will change the factory tilt adjustments. Again, this tilt adjustment adapter is perfectly compatible with the above models, and after replacing the original front end, the back focus length for the camera & tilter plate assembly will not change, so you can still keep the original imaging train configuration. Information of Tilt Adjustment Tilt adjustment is designed to ensure that the camera sensor is square to the entire optical system (optical axis). The following information may be helpful to you. For most amateur astrophotographers, tilt adjustment can be quite challenging. Therefore, it is not recommended for beginners to make adjustments independently, including using QHY's newly released tilt adjustment adapter. This adapter is best suited for experienced astronomers who are familiar with tuning equipment. Fortunately, all QHYCCD cameras are calibrated using high-precision instruments before they leave the factory. Why is the tilt adjustment feature still included? This is because of the entire optical axis alignment of the whole system: A poorly calibrated optical axis, minor deformations caused by an unstable telescope structure or overloaded equipment, and the use of low-quality adapters can all lead to issues within the entire optical system. Before adjusting tilt, please ensure that the telescope is properly collimated. Additionally, we recommend choosing equipment with a higher optical tolerance and avoiding telescopes with very small focal ratios. Calibrating the optical axis for focal ratios below f/4 is particularly challenging. Items included
