Q, from Alan in Oregon:
Does the zoom eyepiece that I have for the 80mm Pentax scope also work on the 65mm ED? If so, what magnifications does it produce?
A: Yes, the zoom eyepiece for your 80mm Pentax will fit in the 65mm ED scopes. Some people find it to be a bit of an awkward setup due to the large size of that zoom eyepiece and the relatively compact body size of the 65mm scope. The magnification of that eyepiece on the 65mm ED scope is 16-48x.
If there is anything else we can do for you, please let us know.
