piggy-backing a finder

[GazA]

hi guys trying to find a way to mount my travel scope to my 130p, i can mount it via the camera both on the top of the tube rings but its not reliable as cannot tighten it enough, would anyone have any idea of a more secure way like tube rings (which i cannot find) or an alternative way to attach the travel scope to the set up?

thanks again

Usually piggy backing is done by attaching a dovetail to the camera mountings and then using tube rings to attach the guide scope to the new dovetail.

Alternatively you could go for a "dual mount bar" and sit the two scopes side by side

(FLO do the tube rings and dovetails - Scope 'n' Skies do a very reasonable "Gemini" dual mount bar)
