In this excellent post, post, billb9430 shows how to make the Baader Hyperion zoom fit the Pentax PF-65ED:

Great news for those wanting a high quality zoom for that scope, but here is a zoom eyepiece to try with the Pentax PF-65: the new (1.25”) Nikon NEP 30-60W:

On the Pentax 65, this eyepiece should give about a 23-47x magnification range, with a FOV of roughly 135’ at 1000 yd. at 23x. If the eyepiece is a good one (I imagine it is) & works with the scope, this could be a very nice combination indeed, a truly wide angle zoom.
On the Pentax PF-80, it should give abt. the same 30-60x range as it does on the Nikon Monarch scopes. While for birding I would certainly prefer a larger true field at the lowest magnification than this combination would give, it still might be a very nice combination.
(The Nikon eyepiece would also be one to try on the new PR-65 & PR-80 Pentax scopes, but they appear to be nowhere available in the US yet- can’t find anything on when or even whether they may become available here.)
