I have a C9.25 that I have moved many times in the last 3 years and have used little. Recently I took it out to use and found it WAY out of collimation. Could someone point me in the direction of recovering gross alignment?
I know how to collimate when it needs "adjusting" but this is way beyond that.
My major concern is "What got it so far out?" If it were correctly collimated in the first place and didn't have something wrong with it, it SHOULD NOT lose collimation, not to this extent, no matter how many moves you've made.
Anyhow, to get it back in the ballpark, stand two meters in front of the corrector and look straight down the tube. Adjust the collimation (by tightening screws) till all reflections are concentric. You can then proceed to collimation using a star.
