Quote:I've thrown mine away. They are a real pain in the behind, always messes up collimation when you've just got it right. I used the ones on my 12" once and then threw them away. It holds collimation just fine without them, as long as I keep the springs tight by tightening the collimation bolts all the way down and loosen them just enough to collimate the primary.
