With a rear adjustment design, even after installing a filter wheel, the QHY Camera Tilter Plate can be easily adjusted and is suitable for most astronomers using the combo of the QHY600PH-SBFL, all versions of the QHY268M, and the QHY268C produced after 2022 (short back focal length version) & a filter wheel.
The Tilter Plate has six sets of adjustment points. You can choose either a three-point adjustment (equilateral triangle arrangement) or a four-point adjustment (rectangle arrangement).
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 the factory focal plane calibration is invalidated and you will need to calibrate the focal plane by yourself.
Again, this tilt adjustment adapter is perfectly compatible with the above models, and after replacing the original front end, the focal length increment will not change, so you can still keep the original adapter configuration, or adjust the adapters according to the standard adapter installation instructions.
