Thanks Les, greatly appreciated! Yes, I didn't have any real expectation of seeing E3. I would still like to have another go at Rup 106 under the very best skies - just a tiny niggle that I seemed to see more than what is actually there. I'll also 'commandeer' a bigger scope if I can to double-check. Need some 'drought skies' - there's still so much moisture in the air that it has to affect observation, even when skies are dark.
There's still a couple more very faint globulars on my list, not presently well-situated for viewing...
Cheers -
