This finder has served me extremely well over the last few years but I'm rehauling my 10" f/5 dob to be an aircraft portable scope and need to minimize. Can you say 'one power'?
The finder was made by taking a pair of 9x63 roof prism binoculars (Little Big Giants out of Hawaii) to my local camera repair shop and having them divide the binocs in two (blasphemy I know but what a great finder it's been). The beauty of this is a correct image finder with a field of view of around 5.5 degrees in a relatively compact package.
The bracket seems to have a curvature for a 12-14" tube but an adapter could be made for nearly any size. Optics are in fine shape as I have a bit of OCD when it comes to my equipment...I'm sure there are those who can identify. The way they covered the area where the two 'finders' connected was a bit rough using a black hardened plastic instead of metal. This has not affected performance at all but I will send you a close up photo if you are concerned about aesthetics.
$54.00 OBO with $6.00 s/h in the CONUS. (SOLD)
I prefer Paypal but will accept either a cashiers check or a postal money order as an alternate.
Thanks for looking!
P.S. This is the right hand side of the binocular and has a smooth focusing diopter.
