Hi all, Since the wind has died down, I had an hour or two outside last night. Transparency was pretty ordinary and seeing even worse. The 22 and 17 EP's were OK, but the 12 and anything shorter was a struggle. Found that PN is Grus from here, finally. This time I tried looking for it with the UHC in place. It is almost invisible without it. Both it and the Quartet were twice as faint as at Glen's. The ring shape that was so clear at Glen's was only just visible with averted vision with the filter. Shows the value of dark skies. The nebulas near 6723 were pretty good with the filter in place. It was just good to be back at the eyepiece again, even though the seeing wasn't great. Hope your 16 is operational again Rob. Cheers to all. Paul.
