Greetings from Alaska!
Don't see many of these around: a Celestron prism diagonal with an integral 1.7x laser-collimated Barlow that is new in the box. Complete with both caps, all packaging material, and printed instructions, there is not a mark on it anywhere.
This could be used in place of an optical corrector or seperate Barlow lens to achieve binoviewer focus in refractors.
