I ordered this long view because amazon.de 2 times cheaper to make birding and digiscoping. But she left immediately. Apparently, according to my research, it is a little Russian roulette, one can come across a good copy or a bottle ass. Personally, mine, 20X in it was not bad, but then impossible to make a correct focus, with more chromatic aberrations that my Acuter 100 achromatic !!! And I speak not of the same dive that even worse! Perish that thought it could make me beautiful digiscoping! Only the adapter digiscoping with SLR pleased me but the pictures it's downright horror !!! In short, it's not a long view I suggest, must limit the leak. Too bad, because on paper it's not bad
