History
MK0 was a proof of concept and the lightest of all versions. It used, like all versions, C-mount lenses as an objective, but they were fixed with a 3D printed thread which proved hard to print right.
The next iteration the MK1 replaced the 3D printed C-count thread with an Aluminum insert, improved the stiffness and was the basis for the 1st Binocular versions. The capability to purge the housing was also intoduced.
The ,as of writing, current version MK2 imprióved further the stiffness and introduced 2 sling loops. Also its the 1st generation which is able to collimate via tilting the Eyepiece and has the option of using a brass thread insert for mounting a J arm. It's also the Version the current 3rd Binocular housing design is based on.
