Hi all...
I need some help.
I recently bought a 10inch newt off another IIS member.
There seems to be something odd about the optical train.
I am having great difficulty focusing.
I have colimated using a laser colimator.
The star shape is very odd when very out of focus.
Also when nearing focus, the diffraction spikes don't match up. (ie up and down spikes are close together but the sideways spikes are apart. This tells me that something is not right in the optical train, but I am at a loss as to what
I hope someone can help please.
Cheers
DJ Scotty
