Moravian Instruments Spare Front Shell for G3/G4 Camera with Two Stative Mounting Positions
Necessary for 1.75" dovetail adapter (Vixen standard).
Please mention the S/N of your camera when ordering. Compatible only with revision 2 cameras.
This Spare Front Shell in combination with the 1.75" dovetail bar makes it possible to attach the camera directly to a telescope mount when used with a dSLR camera lens.
Very large camera lenses would usually come with a bracket and shoe that would enable connecting them to a dovetail bar (via a 1/4" or 3/8" photo thread) then to a telescope mount, however smaller dSLR camera lenses don't have such bracket and shoe, so it's been a difficult task to use a large Moravian Instruments CCD camera with a smaller (i.e. widefield) dSLR camera lens.
Now the 1.75" dovetail adapter (dovetail bar) would be secured to the Moravian Instruments camera's housing and then the camera can be directly attached to a compatible mount via a Vixen compatible clamp. In such setup the Moravian Instruments CCD camera will hold the dSLR camera lens, therefore it is only suitable for not too large camera lenses.
However older Moravian Instruments G3 and G4 CCD cameras had no such mounting positions, so it is necessary to replace the front shell with such replacement that comes with two mounting positions.
Please note, these are not just two threaded holes on the camera body, so you cannot just drill and tap and old camera to make it work as the front shell has been sligthly modified and strenghtened in those places to provide a more secure connection.
Unfortunately this replacement front shell is only compatible with revision 2 G3 and G4 cameras. We would also need the serial number of your camera to make sure that we supply the right part.
If you are using an off axis guider, this will not work.
Actually the shell itself is compatible with an OAG, but you won't be able to attach the 1.75" dovetail bar, so you will have to consider to use a different type of guiding when you use the camera with a dSLR camera lens.)
