Spectra Sure Sharp focuser for sale. It is 4 years old. It is basically a kind of knife-edge focuser which is used to achive a critical focus needed for astro-photography. It comes with a custom-made ring which allows easy replacement of the OM-1 camera body with the focuser. This ring can be attached to any 2" holder. I used it with Lumicon's GEG. The device has a grating, which acts as a multiple knife edges, so you can focus in the center or a little off-center, if you decide you need to. The grating is positioned exactly where OM-1 body holds its film. After focusing with the SureSharp, you replace the device (but not the camera adapter ring) with the OM-1 body and that's it, you should be focused.
$150 plus shipping.
