Dual support for 50mm & 40mm finder scope for Autoguiding (Astronomy / Telescope / Newton)

This Dual support is perfect to fix 2 scope. First one (40mm) to align Object in Telescope and second for autoguiding.
Finder Scope of 50mm is Homemade. I use Old binocular and 50mm PVC tube. Quality of image is very nice for DIY Scope and autoguiding is very accruacy and easly. Little focal permit to find star very easly. DIY adapteur for 50mm tube is fix with M3 helicoils.
