Rusan Q-R adapter for Pulsar Krypton & Proton
The rusan ARK2 mount is available in sizes: 30mm to 69mm. This mount is in one piece and has a screenpostionng option in the mount. This allows the viewer to be placed nicely in the middle of the image.
In the most common cases, with the better scopes, the wall thickness of the scope is 3mm. so if e.g. the diameter of the glass is 56mm (3-12x56) then the required ring size is 62mm. This is the 56MM of the glass, plus 2x the wall thickness of 3mm: 56+3+3= 62MM
For cheaper binoculars it may be that the wall thickness is a bit more. for specefic questions, please contact us.
