Thankyou for the advice.
I really had no idea, thought it was easy!

I have decided to ditch the cradle idea and research home made EQ mounts that I can simply 'plonk' the 12" reflector onto.
Have seen some good designs based on Mt Palomar I think?

Any other links or advice on that type of EQ mount for large reflectors?

Soon I will be hounding for advice on guide scopes and how they work!

Regards
