    Yeah, the Leica extender's potential performance is concerning. My plan is to find one in a shop, bring my scope, and ask to try it out first. If the drawbacks are obvious, I might rethink my options.

    I'm considering getting the 1.8x extender for my Leica APO Televid. I'm curious to see how dark that gets in comparison with the Swarovski. The Leica is only 82mm, so it'll probably be rather noticeable. I expect that a ATX 115mm objective would be most forgiving for brightness retention.

    Wow. I'd love to see some examples of the image quality and light deterioration this causes, however.

    You mean you can stack several extenders together and exponentially increase the magnification to infinity? - In theory?

    I have heard that the booster does not change the AFOV, either, since this spec is determined by the eyepiece alone. Is this confirmed?
