Yes...another collimation question?Posted By Tony Aguire |

Having just spent 3 evenings trying to collimate my LX90 8" SCT I have decided to try a collimator. The question is what would be the best and easiest. I don't want to buy two or three to find the best one.
By the way, if it won't collimate, could there be another problem.
I met a person in my campground who has been in the hobby for years and he couldn't get it any better than myself.
I would appreciate any thoughts you might have on this subject, regards, bob
Make sure the scope is cooled down enough.... Especially an SCT. Check out this webpage that shows the effects of tube currents which may occur if the scope has not had a chance to cool to the outside temperature. The result looks almost like miscolumnation to the untrained eye....
