Thanks Ron,
I've tried that but anything that far away i can see. Its just reallly blury. Looks like a band of mixed colours and the focuser doesn't change this.
The focuser doesn't have a lock knob. No transport lock screws that i can see.
Diagonal and Eyepiece are new and work beautifully on their own. I don't know of any shops i can go to for this but i suppose i need to find one
I'll try holding it to the moon tonight if its out.
Thanks very much for the help and suggestions
