Quote:BTWDid anyone else notice how tight celestron had the screws. My collimation has beeg great for 2+ years. I only went to adjust it after taking the corrector out to clean. I went to tighten one screw (instead of loosen) and messed the head up. Thew were really tight. Maybe that is why the collimation held so well? the ota has not travelled much as it is used in the backyard so I am sure that is a factor also.
