Hi Ron
On collimation: The problem for me was that there are probably as many web pages detailing RC collimation as there are installatons…. I think I now have a collimation procedure worked out. If you get hold of the 16in RC, let me know and I can supply my notes.
The MEII looks to be a mighty beast! (I have to be able to take mine down occasionally…)
cheers
Kevin
