  1. What I guess would be interesting would be to know what the tolerances for the tests are, ie: how much varience from "ideal" is OK ?

    Ultimately it would also be interesting to know the rejection rate for the various models and brands but I guess others have 1st dibs on that information !

    It's a good initiative though and I appleaud FLO for introducing it :icon_salut:

    great read! thanks for that. Have you got any additional tips for anyone ( by anyone I mean me) that doesn't have a finder scope but uses a telrad alone? I know most people use both but cant afford to (be caught..) spending any more on the scope for a good while yet.

    I used to use just a Telrad / Red dot finder.

    With a Telrad it's very useful to have a star chart and to make an acetate overlay with the 4, 2 and .5 degree circles of the Telrad marked on it. You can then overlay that onto the star field where your target lies and get a good idea of reasonably bright stars that you can position within the Telrad rings and note where your target object will be in relation to them.

  3. Welcome to the forum.

    They are very fine scopes when properly sorted. The pictures show one that may be fine or it may not. If there are any issues with it getting them sorted could prove pretty difficult because they are not produced any more (as far as I know) and there are very few owners out there.

    Unless you have some previous experience of scopes of this design I would recommend considering something more mainstream.

    It might help if you could introduce yourself in a new thread and outline your interests in the hobby so that some suggestions of equipment that might suit you can be made.

    So one extender as a starting point.
    This is one expensive Plossl.

    I've almost always bought my Tele Vues on the used market to be honest - they are very expensive now to buy new.

    The Nagler 31mm is now £600+ and Ethos 21 £800+ to buy new - try not to get a taste for such things :rolleyes2:

    I don't wear eyeglasses and I find that a single extender works for me. I use these 32mm TV plossls in binoviewers with VG success and also with my Quark.

    Yep, a single extender did the trick for me and I don't wear eyeglasses when observing. The extender made the 32mm TV plossl a very comfortable and relaxing eyepiece to use.

    Went round to nigels recently and there was a 25mm .965 ep in then. I tried looking through it then stuck a vixen 25mm plosll in. Preferred the plosll i have to say but then the fact its got 22mm eyerelief probably helped me. In terms of sharpness, contrast and colour.  Dont recall there being any difference.  Ih it was solar ha btw

    Funny thing is, if you take the Vixen .965" orthos apart, you find an optical layout very close to a plossl (ie: 2+2 elements) rather than the 3+1 layout of the abbe ortho. They still work nicely though.

    What a great thread.  I've got a 32mm as well, and while it's my default low power eyepiece I have to work hard to position my eye and usually wear my glasses, which means stray light can easily get in.  Interesting that  the eye relief is too much for a lot of people; I find that too and was worried whether I'd cope with upgrading to Ethos etc.

    I had galaxy hunting sessions a couple of years back where a 32mm TV plossl was the only eyepiece I used all night long. I was using an eyecup extender though which makes a lot of differing to the ease of eye positioning with this particular eyepiece.

    FWIW all the Ethos eyepieces have 7mm less eyerelief than the 32mm plossl - the 15mm that the Ethos have can make it difficult for those wearing glasses when observing to see the full field of view but that is a slightly different issue I think.
