Corona Australis & Helix Neb

Hi all
Early cloud cleared to a pretty good albeit dewy night.
First I got a rather deep (for Newcastle) Corona Australis, 14x10 mins ISO 200. No filters at all. Large version here

Then I got the Helix Neb, ISO 400 with LPS filter. Large version here

Both images with Meade 6 inch F3.6 "Cometracker" SN, Baader MPCC coma corrector and Hutech modded 350D.
It got VERY damp as the night wore on. Fog soon covered the lower parts of Newcastle, creeping up the street and wafting in patches over my place.

It was the first proper test of my new "high tech" anti dew system, an electric blanket wrapped round the dewshield and end of the scope. It works brilliantly. Water was running off everything except the scope, whose corrector plate was bone dry.
