Achieves knife edge focusing for astrophotography. SureSharp comes with a custom-made ring which allows easy interchange of an OM-1 camera body with the focuser. It uses a Ronchi grating as a knife ecge. The grating is positioned exactly where the OM-1 body holds the film. After achieving focus with SureSharp (instructions included) replace SureSharp body with DuoView to use an eyepiece to find and compose faint objects for photography. Remount the OM-1 and shoot. Both for $125.
