Diagonal to allow iOptron back focus

[niko]

Hi, I've got an iOptron tube I want to use as a guide scope but just realised it's missing the diagonal so there's not enough back focus. Anyone got a spare lying around for a bargain price?

Cheers

When you say guidescope, I gather you mean finderscope??? For guiding would you not just use an extension tube and then your guidecamera?

If you are after 1.25" diagonal to use as a finder, I am happy to give you one for the cost of postage. Its just a basic diagonal.

Cheers,
Matt

thanks Matt - very genrous - I'll PM you

I don't have an extension tube so a diagonal will perform the same function. My intention is to use this set up ans the guidescope for my ED80 piggyback style. I think it'll be a step up from the converted finderscope I have been using
