Thanks for your input. One more question I have a friend who has a Swaro ATX 80 mm with the 20-60 mm zoom, that I had a chance to use last weekend. Can you tell me which of the 2 scopes above the Opticron 77mm with SDL v3 or the new Swaro ATS 65 mm with 20-60x zoom would be closest to quality of the Swaro ATX. Thanks,
Hi,
it really depends on sample variation... in theory the 65mm scope has lesser resolving power than the 80mm examples. But in real life the aberrations from manufacturing will be the limiting factor and it is quite possible that the 65mm example (or a cheap 77mm Opticron) might be better. You have to test them - if you get your Opticron, meet up with your friend again and compare - of course masked and with distance ;-)
Joachim, whose old but quite good Kowa TSN-3 with the Opticron SDLv2 has so far held up very well vs. lots of current alpha scopes...
