Is anyone familiar with the operation of the fieldscope attached on the D70?

Nikon just came out with the ED50 that, with FSA-L1 I can attach to a D70.

but they are not clear in their documentation other than saying it provides 1200 and 1500 35mm equivalent telephoto.

Does ED50 itself come with an eyepiece?

Anybody experienced in a SLR/Fieldscope setup?
