Collimation for GSO RC10 - need help
I've done a lot of searches and read a few guides, but I'm unsure what's the best way to sort out the collimation mess that my GSO RC10 (CF version) is in right now (I seem to be getting stars that look like comets).
For those that have this scope or have used it, what do I need to get/use to sort this out properly?
