Designed for the TV102 or other refractors in the 800-1000mm FL range.
This reducer/flattener was custom made at TeleVue to reduce vignetting in 35mm photography.
All you need to do is remove the inner ring of your t-ring, place the t-ring on the R/F and tighten the three set screws.
Threaded for 48mm filters.
Includes both dust end caps.
This is a one of a kind piece of equipment. Regular R/F's go for $265 and you'll have much more vignetting in your images. I'll sell this custom one for $225 and you'll get less vignetting - includes shipping via tracked Priority Mail in the US.
Thanks for looking!
