Just for the record I am using the H12.5 EP with the 60mm refractor not the 8" newt. The tasco gear is 3/4" so the are not interchangeable between the two scopes without an adaptor - which I don't have. I am using a 6.5mm (its actually 6.5mm not 6.4) and a 25mm plossl that came with the 8" newt.

The collimation does look reasonable, it is off slightly in one direction but it seems to be centred pretty well. The guy I bought it from said he had it set up perfect so don't mess with it. It could have moved in transport though.

I can locate Jupiter, its not quite as bad a Venus in that it looks like more than just a star but only just. It appears as a very small round object < 1mm in diameter but has no definition with my 6.5mm EP. Its only the fact that its not a pin point star and is slightly roundish that I realise its Jupiter.

I just tried looking at something in the distance during the day and I can't really focus on it. its not because of the travel in the focuser as I can run through the point of focus with more travel in the mechanism at my disposal in both directions. It is because when I try to focus on the object it just doesn't become completely clear at the point of focus and then goes out of focus again as I move through that point. I tried both EP's and the 25mm gives better focus than the 6.5 EP - the 6.5 is terribly blurry.

It seems to me like the EP's are not preforming. I pulled the 6.5 apart and checked lens configuration and cleaned it - made no diff, still the same.

Any suggestions? - I'm all ears!
