At daylight as we know, this is less important. This is not in the quote but you talk about it; nobody says the APM has bad resolution etc, but the CA kills everything else at high mags. And i use that word because one of the owners use it few times when we trade pm's. The members i talk with are from cloudy nights (most are posting on that thread you link) to binomania, astrofili.it and anothers italian forums. But i also ask about the BT80, previous model of the BT81, with 900 f/l!!! ... the oberwerks BT100 ... i even remember read reviews on binomania of 125mm binos! guess what? 40x dead end on terrestrial ... about the APM's i dont want you to spend 1000 euros on a bino, 500 on ep's, and who knows how much on a tripod for something limited to 40x and you cant take it nowhere without a wheelbarrow</p></blockquote><p></p>
