I recently purchased a set of used Zeiss EP-L 10/x20mm EP's for my TV Binovuers and was shocked to note that these particular wide field EP's did not fit my Televue Binovuer with the compression rings as these EP's were designed for microscope use and had a sightly smaller barrel size at just 30mm @ 1 inch, and 31,75mm is standard for the 1.25 inch Ep mounts...I was a little chagrinned and frustrated as I was lead to believe by a fellow star gazer's advert "...the only eyepiece I use in the binos. I change magnification using different configurations using the AP Barcon and Baader Fluorite Barlow. You will be very impressed" ....I am impressed with the quality of these Ep's, but with the loose fit I was unable to use them in my Binovuer..... WHat to do??
Well, I did some research and found some commentary on the manufacture of a retrofit which can be fabricated ( lathe turned, threaded for filters and fully anodized) by APM telescopes in Germany....
I wrote Markus Ludes at APM and sent pics and my requirements for the retrofit, and for a reasonable fee (including shipping from Europe) these new tubes will overlay my existing EP barrels,,,,Problem solved !
Anyone out there with antiquated yet excellent optics, or wishing to experiment, compare or use the oldies but goodies on a new telescope rig will be happy to have found this excellent service and executed design retrofit....
I am not affiliated with APM but would highly recommend using their services to accomplish the retrofit for over-sizing a barrel for use in a modern scope..
Clear Skies !
