Pentax PR 80 EDA eyepieces (1 Viewer)

That Sucks ! ... I was hoping you would have received a good unit with a good zoom. Since I am in the states, I choose to keep my PR65 body but sold the zoom for $25 indicating it was as defective with specs also. I choose not to send everything back for a refund because I did not want to take the chance of getting a dud body unit as well. I tried both a XW20 & XW14 Pentax eyepieces with both giving a crisp/sharp view. The APM 24mm eyepiece also worked very nicely but when I tried a Zhumell 18mm Planetary eyepiece it would not focus to infinity, it was sharp out to about 1,000 feet. I wonder if the reduced focal length of the Pentax PR 65 which is stated as 370 will be a deciding factor for any particular eyepiece not focusing correctly or if its my corrective lens in my eyeglasses.

Hi Boogie, sorry to hear the scope didn't meet your expectations. I can recommend the PF 80 without hesitation. I bought mine new for £539 from Microglobe and it is a cracker, I"m not big fan of zooms, having said the Baader zoom provides excellent views throughout the range. I've been trying a few plossl eps, narrow FoV but really tack sharp, even at x60

Is that the MK IV Baader zoom which I presume focuses at infinity?

I had one of these scopes years ago with the big Pentax zoom but sent it back due to really bad flare with a low sun. Has this been cured may I ask?

Hi, it is with the Modified MK111, it just about reaches infinity focus on PF80, not quite on the PF65. To be honest I think under certain conditions flare is inevitable. I also had the Pentax zoom, much had better build quality than the Baader and waterproof. I preferred the Baader optically though.. I haven't tried the new Baader zoom, but if it gives you nearly an extra 4mm of back focus, I think it should be ok.
