Well i think that with everything thats been said my scope should be absolutely screwed but it isn't.

My Primary isn't centered in the tube its visibly out

My focuser does not give any tilt adjust (its a FT so it isn't a crap focuser)

I admit that it isn't a F3.8 but its classed as a fast scope at F4.7

What the cats eye gear does is align the optical axis with the focuser axis very effectively.

Be really careful when doing your alignments as at F4.7 i can barely see the P2 and from every thing i have ever read it gets worse the faster your scope gets so is it something that you may be using the wrong reflection. I know i was for a while untill i got a very bright led that focused down onto the hot spot. it was then that i realised that i had actually been using the wrong reflection.

Like i said before once you have those astrisims lined up .... you cannot be wrong unless your auto collimator is up the duff.

If you give me a few months ill be able to give you my thoughts and experiences as im just about to commence my wide field newt fast newt project.
