After Astrofest I did something in a series of silliness and I need some help.
The primary mirror of my 10"GSO RC was filthy and so I decided to clean it. While I was at it I decided to clean the secondary as well.
No problems - two clean mirrors back in the tube.
I thought it would not be a problem re-collimating it but here is where my world imploded and I wound up with a totally messed up scope.
Total miss alignment. Bought a cheshire eyepiece but I just made things worse.
When collimated its a beautiful scope - so how do I get back to both mirrors being collimated and what hardwear/laser equipment would people recommend?
Thanks for any advice.
