Detail Image

This unit has a custom bracket, which attaches firmly to your telescope's Optical Tube using heavy duty adjustable straps. The bracket holds a highly specialized linear servo actuator which pushes an adapter that opens the shutter.

The bracket can be mounted in any orientation around your Optical Tube. Whether Top (as shown here), Bottom, Side East, or Side West, the bracket remains rigid and provides exceptional holding strength.

The unit will support Optical Tube sizes from 3" to 24". Larger apertures benefit using a split shutter, where 2 actuators are used to open each half. We recommend using high quality 5-ply "airplane grade" plywood with a 5-6 mm thickness. We provide a drawing so that you can make the actual shutter for your own needs or we can supply one.

Note on this cover, we've applied a closed cell foam seal, but you can use window insulation tape around your Optical Tube perimeter to result in the same seal. Some users have used commercial foam-core, which is stiff and very light, in highly satisfactory installations.

Comes with a 12" 3-wire cable, mounting straps, hardware for the shutter, and adhesive non-slip tape to assure solid attachment. No screws are required; tape may be removed without damage to your telescope.

Plugs into ScopeShutter Controller, sold separately. Extension cables are sold separately.
