    Default 15mm GSO SuperView Revised Autopsy



    Below: unborked complete 15mm Revelation Astro SuperView (original eyeguard has been replaced with a standard fold down GSO).

    Three lens groups (field lens to the right):

    15gso1.jpg

    Closer view of lens groups:

    15gso2.jpg

    Eye lens (left) and second lens close up:

    15gso4.jpg

    There has been some speculation as to the actual configuration of the four lens eyepiece and whether it actually is 1-1-2 or not. I see no evidence that either the eye lens (below), which is asymmetrical, or the second lens is a doublet of any description.

    I do think that the field lens shown below is probably a doublet.

    Any thoughts?

    Hello Shorty Barlow,

    another very good dissection!
    When checking the lenses materials on scattering or when checking the doublets and triplets,
    I take a green laser beam.

    Thanks. I think a laser would be an interesting tool to use on eyepiece components.

    Not sure if this will quite do lol.

    ... I take a green laser pointer, purchased for 25 bucks.

    That's a standard and widespread routine when checking the optics, ray tracing, etc.
    I have already posted the use of the laser beam pointer here somewhere in past with comments, see the attachement.

    Best,
