Piggybacking a second scope

[david_r]

Hi,

I have an 8" Newt that is held in place with a pair of these...

I have now acquired a second scope (102mm refractor) that I want to piggyback on the newt, then use either the newt or the refactor for having a stab at doing some imaging.

My numpty question is what is the easiest way to mount it? and how does it connect the ring mounts above?

I guess I need something like this...

But how does this connect the rings above, if at all?

Thanks,

David.

The rings in the first picture have threaded holes in the top and the rings in the second picture have holes in the bottom. You just bolt the two sets of rings together.

OK Thanks. I'm not sure the threaded post with the locking wheel comes out of the rings I currently have, although I'm sure I can pursuade it with some subtle 'molegrip' action.

Do you know what the thread is? I know its the same as a camera\tripod mount but that's it.

Thanks

David.

The camera attachment with the knurled wheel will easily be removed; a large star screwdriver from the inside will get it out. It's a standard 1/4" UNC thread, the same as your camera tripod etc.

Not sure, but the attachment threads in the guide rings MAYBE 6mm??? Someone who has them, will be along in a moment to confirm........

It'll come out with a little "persuasion".

The rings in the first picture have threaded holes in the top and the rings in the second picture have holes in the bottom. You just bolt the two sets of rings together.

However, you will find that the distance between the guide rings is now too great to match your "102". In which case you will have to bolt a bar to the existing rings and mount the guide rings, the correct distance apart, to that bar.

That's a very good point Steve. Had not thought of that. I'll measure it all up tonight and check. Thanks

Aha!! I hadn't thought of that....
