View Full Version here: : Mounting finder scopes

08-07-2017, 11:30 PM
Does anyone have a Bintel GSO 10" RC truss tube and has attached a finder scope to it? I have a 50mm scope that I want to attach but the finder shoe bracket on the scope is 'square' and I haven't needed to look for a bar that will fit that yet.

Any options?

Any chance you could take a pic of the base in question? A bit hard for imagine just from your description.

Easiest option would be to get a new optical finderscope bracket and shoe of the standard shape. About $60 I reckon?

Hi Tom,

thanks for coming back to me. It looks like this (https://flic.kr/p/VtJRGt) and this. (https://flic.kr/p/VtJS8D)

My finder scope rings have what looks like something that will mount on to a vixen style bar (looks like this (https://flic.kr/p/VtJSTM) when compared to a losmandy D style bar).

I wonder why the finder scope saddle would be square and have only one thumb screw?

That finderscope saddle is remiscent of one used on some Russian maks. Remove it and bin it.

One solution would be to buy a short vixen rail with central slot and cut off a piece to fit.

The bracket is also popular with red dot finders from William Optics and others.


The Vixen style finder bracket is more widespread, so changing it over seems like a good idea, but you'll find that the mounting holes sit the other way there (radially instead of axially with respect to the telescope tube).

Yep, fair enough.

Guess GSO made a choice there and went in some very odd direction.

I'll use the losmandy bar on the top I think and get something to attach to that.

Thanks for the advice!

Simon if you're open to buying the complete solution I'd suggest this:


The shoe might even fit the existing holes.
