Where can I get 70mm tube rings

[beamer3.6m]

I plan on using a Bresser Skylux 70mm scope as a guidescope and want to mount it on my Explorer 200.

Any ideas where I can get tube rings to fit as I think the scope comes with a strange clamshell style clamp.

The tube rings need to be bigger than the actual tube of the scope as the aim would be to make small adjustments to centre a guide star using screws in the same way you would align a finderscope.

Not suggesting buying these from Scopes n Skies (see other posts on problems with that company) but they are typical of what you need - check near bottom of page. http://www.scopesnskies.com/second-user-bargains.html

I have bought s/h stuff from SnS without a problem.

If you cannot find a set of rings suitable for your scope you can make some by buy a standard set of rings say for an ST80 (any skywatcher supplier should have them) and drilling holes to take the adjustment screws.

Thanks Scotastro.

A fellow SGL member provided a pair of 100mm rings which have proved to be perfect,
