9 Nagler type 1 (1.25/2") Barrel extension and Skirt. *Sale Pending*
To use 2" filters on your 9Nagler type1, you need a barrel extension, however, if it is not the latest, or in the 9's case, the last production run, the eyepiece skirt will not have the threads for the extension.
The item on the left is the barrel extension and will accept 2" filters. The item on the right is a replacement skirt with the threads.
This skirt may work with the 22Panoptic or other 1.25/2 eyepiece. Please check with TeleVue.
Lastly, I have found the barrel extension to serve a parfocal function with 22Nagler or 31Nagler.
Selling as a set for $45 shipped US destination. Money Order or Cashier's check please.
Thanks for looking.
