Hi
I found that with my RC 8 I needed all 3 of the extension tubes and the moonlight focuser fully racked out to be able to see the annulus at I using the Tak Scope
I don't have an issue with the spider so cant help with that
Enjoy the scope.

That makes sense to me David something i didn't think to try.
Paul I have a new GSO 14RC.
Would i require a collimation ring to get it all lined up with optical axis with the 14?
Took me a while to even work out the adjustment bolts for the primary not much info around the net for these scopes.
But i did read some posts you made regarding the importance of a TAK for the collimation procedure and now that i have played with it a little i understand why it is an absolute necessity for collimation.
.
The whole idea of making rings inside rings inside rings all perfectly concentric does sound a bit daunting. makes for a great challenge.
My new 2.5" focuser arrived today finally so when i get the time off work next week i will install that and attempt some real collimation.
I have read about the possible cascading downward spiral of misalignment that can occur when not being very careful with collimation as Glen has pointed out.
I hope i don't end up going down that path.

If you need to ask more questions please feel free to do so. BTW your rings image made my explanation so much easier. 16-09-2015 05:39 PM

Glad the diagram helped would be a very difficult thing to describe with out it.
