Hi all
After having recently purchasing a new 10" LB, and never collimated before, I thought why not play around with the screws on secondary and primary, mis-collimate it (if that's a word), then try collimate from scratch to try and master it.
Several hours later I still can't get the primary mirror exactly aligned with the secondary
It looks something like the picture attached. I have turned the secondary screws to tilt it and the refelction of the primary seems to stay hidden in the corner.
I've also tried loosen the main centre screw on secondary and move it up/down but to no avail.
I'm using a Orion Chessire/Sightube collimating piece. Your help is greatly appreciated thankyou.
