Still, I bet my scope is easier to collimate, heh :grin:

Before they messed up te primary it would have been a nightmare. I can imagine doing with a cap/cheshire, having to walk 50 or more meters to reach the end of the tube and fiddle the adjustment screws, walk back 50 meters, look through eye piece etc. :D Apparently it was so bad, here are some comparisons before and after the corrections were made.

Hubble would even challenge the best around here. I'd like to see Astro_baby and the astonomyshed do a series on that :D
