Message: <blockquote data-quote="leybold12" data-source="post: 3288137" data-attributes="member: 121414">I have been working on the same problem but took a different tack. I already had two Pentax XL (10mm and 20mm) and a Baader 50-70 degree zoom 1.25" eyepieces for my Pentax 100mm ED scope but wanted something lighter and compact to backpack. So I started looking at other 1.25" eyepiece ED scopes. I ended up getting the Pentax PF-65 EDA II. The scope, carbon fiber tripod/aluminum two way head, backpack and two 70 degree eyepieces total 9 pounds. I am looking for a way to retrofit the Zeiss or Swarovski 25-50mm wide angle zoom to it so I only have to take one eyepiece. The Swarovski almost fit deep enough to work but I could only focus out to 150'. I currently looking at focal reducers to fit the 1.25" mount that I would machine to fit the Swarovski eyepiece and reduce the zoom range of 20-40x to 15-30x which is closer to what I want.I thought of buying a used Swarovski 65mm scope body with HD glass but then I couldn't use the Swarovski zoom on my Pentax 100mm ED (not to mention the extra $1300 over the Pentax PF-65 EDA II body).</blockquote>
