Attaching a Lens
The LensSlider has 3 petals on the front inside diameter that clamp down onto the mating flange
petals of the camera lens. Unlike with a camera body, the lens can be inserted in any of 3 possible
orientations on the LensSlider. Any of these orientations will work.
Start by loosening the scalloped lock ring. This only needs to be loosened about ½ turn.
Align the flange petals on the camera lens between the petals on the LensSlider and insert
the flange until it seats against the black lip above the red lock ring.
Twist the lens clockwise (Canon) or counterclockwise (Nikon) and you will feel it stop
when fully engaged.
Tighten the lock ring and the lens is securely mounted to the LensSlider.
Attaching a CCD Camera
Any camera with a 17.5mm backfocus and 42mm T-threads will attach directly to the LensSlider
and work correctly. This includes Starlight Xpress, ZWO and some QHY cameras. Atik cameras,
which have a 13mm backfocus distance, will require an optional 4.5mm spacer to set the correct
distance from the lens to the camera. Another optional adapter is available for cameras with a
CS-mount, including the Starlight Xpress Lodestar and Ultrastar, and some Mallincam models.
To attach a camera, simply remove the nosepiece from the camera and thread it onto the male
threads on the Filter Slider or appropriate spacer.
