Preliminary adjustment for the OAG 2

I was able to adjust the mirror dovetail of the OAG, thanks to a .050 allen wrench I bought from Uk (thanks Tim!). Now I need to change the orientation of the guider and would like to know which allen wrench I need to remove the four screws. Even this is a measure that it's not easy to found here!

Giulio,

This is what you need. See attached file.

 

Hello Tim, I know this document, but my problem is that I should modify the orientation of the autoguider as in section 2. To do so, I should rotate the off-axis guider's 1.25" draw tube, by removing the four socket head screw and re-orient the draw tube. As in the previous case, I have tried all the allen keys provided and all the allen keys that I have, but none fit the socket head screws shown in fig.2. The size of the allen key should be between 3 - 4 mm. Probably, as in the previous case, is an english size and I have to order it on ebay. To do so, I have to know the exact size. Do you know it?

 

Giulio,

After looking at the drawings it a 9/64 hex key.
See attached as well.
Cheers
Tim

 

To confirm it's these cap heads...

 

It is exactly those. Thanks Tim!
