I have a set of Kowa bigeyes in a custom bracket for sale. They are TS612 tubes with 30X eyepieces. The eypieces in these tubes actually make this system 25x.
I'm asking $1,200 for them.
Below is a breakdown of what I paid to put these together
Tubes - 350 each
Eyepieces - 140 each
Bracket - 350
If interested PM me and I can either email or text pictures of them. Would be possibly open to trades doesn't hurt to ask. (build parts, guns, high end optics, reloading supplies)
