orion 60mm multi-use guide scope on a Skywatcher Evostar 150ED

[bluesilver]

Hi,  Just after anyone thoughts of advise on using this Guidescope from Oriion as a Gidescope for my SkyWatcher Evostar 150ED

https://www.astroshop.eu/guidescopes/orion-guidescope-60mm-multi-use-guide-scope-with-helical-focuser/p,51934

It is all mounted on a Skywatcher AZ-EQ6 

Would it be too big and heavy,  or is this what they are purposely built and designed for? ( the Orion Guidescope that is )

It tells me that it comes with Vixen style dovetail mounting bar,  I could be wrong here,  but i think that is the same type of mount that you usually find on a finder scope mount?

Would i better off replacing this with a better setup to make it more stable?

If so can anyone please recommend a good setup or a link to any suggestions.

Any input would be greatly appreciated.

Thanks.

Hi

That seems an awful lot to pay. Have a look here. When ordering ask for a warehouse near you.

The supplied dovetail is as you describe: rubbish. Fix it to a proper 4cm Vixen plate, replace the metal screws with nylon (avoids differing expansion rates), use a heavy clamp to fix it along a third dovetail along the top of the tube rings or, if permanent (as in you have only one telescope), bolt it directly to said.

Or use an OAG.

Here's ours on a 130pds.

Thanks for the reply,

For the 4cm Vixen plate you mentioned,  is this the plate you was referring to:

How do the nylon screws hold up,  can you still get enough tension on them to stop the scope from sliding around,  I would of thought that they would not hold enough pressure on the scope and would strip easily,   but saying that,  what thread size are they if you don't mind me asking?

A tad hesitant ordering out of Chins at the moment though,  wouldn't know if you would get the product or not coming in from there.

That would do. Or simply a length of 40mm x 12mm aluminium bar and an angle grinder.

Ask that it be shipped from a European warehouse.

For guiding, everything must stay put. The nylon tipped steel screws allow movement of the guide telescope relative to the rings; nice oval stars!.

Thanks again for the reply,  might have to hold off on it for a while as it is only stocked in the China warehouse,  out of stock in the others.

Not to worry,  but thanks again for the link.
