Photographer/Hack......either/or

Thanks for this - I think on my little iPhone experiment last night you're totally right. Waiting on getting the right adapter for my camera to get the DSLR out (can't happen quickly enough....).

I have a notebook I am writing all these clever tips into.

(I promise I won't be quite so over enthusiastic once uni starts back....I go under my rock for a while then!)

Since your a photographer, let me present a different analogy as I have learned it, to how EP's seem to work. I have determined that telescopes are like zoom lenses, but operate slightly differently, instead of increasing the focal length and keeping a constant aperture, the basic focal length remains constant and the effective aperture changes. So as you decrease the EP focal length, the AFoV (Apparent Field of View) gets smaller and smaller, increasing magnification.

So you have to be very attentive when looking into the EP to find the right spot. It's like looking through a long tube at a bright light, if you are not pointed straight at the light, you can't see it.

Hope that helps as you try the different EP's again.
