SW 9x50 right angled erecting finderscope as guide scope?

Hi all,

I was wondering if anyone has used the SW 9x50 right-angled erecting finderscope as a guide scope - using a ZWO120MM mini or equivalent?

You would need to remove the right angle correcting bit in order to fit the camera adaptor to the back of the tube, so you'd end up with the same result as starting off with the standard straight through finder

The right angle finder will also need some sort of extension tube, along with the camera adapter, to achieve the correct overall length.

OK thank you. Sounds doable then but just a bit of additional faff.
