2-inch 2" telescope eyepiece adapter ring slim 67mm camera lens filter threads

Description

This listing is for a specialty adapter for film or digital astrophotography - it gives a 2-inch eyepiece receptacle for your telescope 67mm female filter threads for mounting cameras or for converting beautifully large photographic lenses into eyepieces for your scope.  It's quite slim which some telescope setups will need if they lack enough back focus distance with other adapter sets.
One example application would be for securely mounting a medium format film camera to your quality telescope focuser - namely, a Pentax 6x7 camera via a 6x7 67mm reverse adapter (check my other items).  The 2-inch eyepiece flange is threaded for eyepiece filters.
There were three available at the time this listing was created - quantity 1 = 1 adapter - these are sold individually.
I'm not sure when, where, or by whom, this was manufactured, but these were acquired in the same stock as several Parks (Japan), Lumicon, and Pentax (Japan) camera/telescope related bits and bobs.
These will ship via USPS First Class Mail within the US and will be packed with bubble-wrap and cardboard.  An upgrade to Priority Mail is available.
Thanks for looking!
