What is the primary function of the Player One M48 Tilter Plate?
Its main purpose is to allow imagers to connect Player One Artemis and Poseidon series cooled cameras to popular third-party filter wheels from brands like ZWO and QHY. It also includes a tilt adjustment mechanism to ensure the camera sensor is perfectly parallel to the focal plane, resulting in sharper stars across the image.
Will this Player One M48 adapter work with my ZWO EFW 8-position 1.25" filter wheel?
The manufacturer's compatibility list specifically mentions the ZWO EFW 7x36mm, EFW 5x2", and EFW 7x2" models. While other models with the correct M48 threading might work, only the listed models are officially verified for compatibility.
How do I know if I need to adjust the tilt on the Player One M48 plate?
If you take an image of a dense star field and notice that the stars are perfectly round on one side or in one corner but appear stretched or out of focus in the opposite corner, you likely have sensor tilt. The adjustment screws on this plate allow you to correct this by slightly altering the sensor's angle until stars are sharp across the entire frame.
I have a Player One Poseidon camera and a QHYCFW3S-SR filter wheel. Is the M48 Tilter Plate the right part?
Yes, this is the correct adapter. The Player One M48 Tilter Plate is designed for the Poseidon series cameras and is compatible with the QHYCFW3 series of filter wheels, including the "SR" (Standard) model. It will provide the correct mechanical connection and allow for tilt correction.
Does the Player One M48 Tilter Plate add significant back focus?
Like any adapter, it will add some length to your optical train. While the exact thickness is not specified, tilter plates are generally designed to be as thin as possible to minimize back focus consumption. You will need to account for its thickness when calculating your total back focus distance from a reducer or flattener.
Is this Player One M48 adapter compatible with non-cooled Player One cameras like the Mars-C II?
No, this adapter is specifically designed for the larger cooled cameras in the Artemis and Poseidon series. It is not intended for use with the smaller planetary cameras, which typically use a different connection method and do not require this type of adapter for filter wheels.
