Title: collimation
Post by: vincent on 18-Nov-2008 17:37:53 GMT
hi
 after just getting me new scope im wondering which tool do do it with cheshire? laser? and the cheapest place to buy one.
im drifting towards the basic sight scope pinhole/cheshire type as ive been reading that laser collimators also ironically can require collimating, and i dont wanna have to make/buy a thing to rest my laser on to test its collimation...like the oozalum bird i dont want to dissapear up my own backside.
any thoughts or suggestions greatrly appreciated :)

Hi Vincent, which scope did you buy in the end. the Cheshire collimator should suffice but again bring the scope with you up to Pex and someone will show you how to do it we have a cheshire and can do it for you.
cheers
