  1. Sat 10/03/2012 14:00-17:00 Norfolk Community Primary School

    All kinds of fun with Sheffield Astronomical Society and Sheffield Physoc.

    Mars rover, stomp rockets, badge making, build a planet, solar telescopes (if Sol graces us with her presence), presentations and more!

    There are 2 ISS passes during the time, so Sheffield Amateur Radio Club are going to try and make contact (no promises there ...) :)

  3. That's the thing with fast scopes - they don't suffer lower quality eyepieces, although I think that Hyperion may have been a lemon - the one I had was fine although I did have some focus travel problems in the 16" Lightbridge (not enough outward focus travel) - was still miles better than the Meade QX that shipped with it.

    The ES70s will be variants on the Erfle - 5 element design is a dead giveaway. I'm very happy with the 100s and 82, a hair away from the TVs for quite a bit less money, but I've never seen the 70s ...

    I have the full set of BST Explorers (OK, one of them is an AstroTech Paradigm, but they're the same thing). Really happy with them for the money. There's a bit of coma towards the edge, but you'll still get that with real top-end eyepieces on fast scopes - the only way out of that is to add a coma corrector into the optical train.


  4. Ajg, how do you get on with the baader zoom?

    Edit; sorry, just noticed the separate thread regarding the zoom.

    Aye, best asking in the thread - I believe FLO have some stock now.

    Quick summary of the hyperion zoom - it's good - very versatile, and the click-stops are useful in the dark. Way better than the usual zooms you see which all seem to be clones of each other, although I haven't stacked it up against some of the other premium zoom EPs ...


  5. My criteria was "can I get the base through the interior doors of my house without taking it to bits?"

    The 300P was the biggest thing which met that requirement so I bought it. ;)

    2" of additional aperture doesn't sound like much, but look at it from the surface area of the primary.

    250 = 491cm²
    300 = 707cm²

    Looks a bit different now eh?
