Powering the 460EXm issue

You're right! It was a crappy power supply...
I just received the other one:

I have tried for it with a few darks and I didn't see any problems - yet...

I'll get back to you guys if I have any more problems during a "real" astro session!

Your findings seem to be the same as mine, the cheap ones are cheap for a very good reason and it well worth paying a little more.
