Hi Ken. It's great that you got your Barlow & Comb.Cheshire. You *MAY* find that the X hairs are *GOLD* wire. Be vewy,vewy careful as they are extremely soft & easily broken. As you found, the film can is O.K. to do rough collimations with, but the Cheshire is best. I don't have the combo. model,(X hairs), & has been dropped a few times with no damage. Be careful with your's tho.
Nice to have a correctly collimated t'scope, ain't it? Just have to star test it now! Regards, L.
