greetings all,i've been thinking about different scope combinations and started wondering about which eye pieces might provide the best view with different apo/non apo combinations.
let us imagine we have an apo 77 televid with 32+wide angle lense lined up next to a non apo 77 televid but with a 20+wide angle lense.
which scope would provide the brightest/best view?.there is quite a saving with the non apo scope but would using a lower power ie 20+ wide angle eyepiece have a sufficient advantage over the apo version with the higher mag eyepiece and hence make the non apo set up a cheaper and better choice?.the trade off is of course lower power but i have come to prefer using my zoom down to 20mag [brighter wider views].
the same comparison could also be made of the smaller televid models and other scopes that offer apo/non apo options,ie swarovski and opticron.
