Levelling plate adjustment
The front plate of the Apx60 has an M54 x 0.75 mm female thread to connect
to telescopes and accessories. It is adjustable to allow the user to fine tune
the camera to the optical system. The front plate has been pre-set during
manufacture accurately to the level of the sensor and normally does not need
adjustment. If the user is having issues with misshapen star shaped on the side
and corners of an image this method of adjustment can help.
Please only ever make the tiniest of adjustments to one set of screws at a
time. Adjustment is similar to collimating a Newtonian telescope. The headed
screw when turned clockwise will “pull” the front plate towards the camera
and the grub screw next to it will “push” the front plate away from the camera.
The screw is located in such a position so adjustments can be made with
the camera in the image train to allow the users to make adjustments without
removing the camera from the telescope.
It is suggested you make adjustments using the following method: Take an
initial image, inspect the image, make adjustments, take another image and
inspect it for changes and repeat this process until the desired results have
been achieved.
