I just ordered a new Pentax pf65ed straight and then ordered a Baader Hyperion 8-24 Mark III zoom eyepiece but then I noticed that on some of the threads on this forum that it may not work. Does any one know why it won't work? I am primarily using this scope for viewing at distances greater than 200 yards and need to have zoom capabilities as I will packing long distances and carrying multiple eyepieces is not feasible. If the baader will not work what is my best bet for a zoom eyepiece?
