    Default 16" binocular telescope.



    Hi. I'm just building a 16" binocular reflector and thought I'd put some pics up of progress to date.
    I've been on it for about 10 weeks so far.
    It's got electric eyepiece width and diaoptre adjustment, with multi memory capability. The main focussing is done by raising or lowering the main mirrors.
    This is so the eyepieces don't have to move up and down, as they're angled in at 2 degrees each, to give a more natural view.

    I found with my last binoscope, a 12", that parallel eyepieces gave me a headache after a while, as it was unnatural trying to form an image with both eyes, say 5 foot in front of me, but the eyepieces had no coning angle so they were trying to convey an image at infinity.

    Sorry, I'm getting too deep, too early. I'll see if the pics come out first.
    ..............................


    They didn't, I have to have 5 posts first, will sort it later.
    Cheers.

    Thanks. I know it looks a bit Heath Robinson but due to the usual lack of funds I've had to make it from bits and bobs lying around in the workshop.
    The eyepiece adjustment works well on the servos and moves between the three variable settings spot on.
    I'm wondering whether to enclose the 2 sides in big tubes or to leave it all open, as in, I don't know how much improvement in contrast it would make?
    The main focus, by moving the main mirrors up and down, could also do with being automatic, with a memory function.

    Next step is to get some drives on the axis and then sort out some form of goto system. I've not come up with a goto for under £2000 yet though.
    Can't wait to get it to a dark site.
    Cheers.

    That looks seriously awesome. Can I borrow it?

    (I can see a potential flaw though: anyone with occluding ears is going to lose aperture!)

    All you need now is to attach a chair so someone can sit and swivel with the whole assembly! That thing looks amazing, great work.

    I see a third option: a light wire frame supporting a black "tent" over the whole shebang.

    Are you doing your own powder coating "in house"? I bet you have a nice clean, well ordered workshop.
