Pentax Lens (PK) adaptor for 1.25" Astronomy Camera

This adapter will allow you to connect an astronomy type camera with 1.25" nosepiece to a Pentax K mount lens.

The design is for the sensor plane of the camera to be 10mm inside the 1.25" holder, making it ideal for cameras that have a 1.25" profile throughout (ie QHY cameras) or the Altair GPCAM.

If you have a camera where the sensor cannot be placed this far within the 1.25" tube, you will need to alter the design to shorten the tube.
