Gee that made a difference. Much darker sky background and much improved contrast without that annoying greyness and speckling. There also seems to be more detail in the PN's centre. Not sure about the delicate filamentary edges, maybe some detail lost there, but that area seemed to merge into the background a bit. Very good result. Well, it's dark outside, a might have a bit of a session. Cheers, Paul.

I’ve attached another I triedto remove more of the background digital noise. I’m using fairly short exposures but the ISO was up at 1600 which will introduced a bit of noise. Was hoping to have another go tonight but she is blowing a gale out thereat present. Got a call from Isaac today, my mirror is finished and ready to freight back.With any luck they picked it up today and it will be back up here tomorrow.If so I shoot over to Goonellabah and pick it up. So get ready for a wet weekend : ( Cheers,CS Rob From: nswnra-bounce@xxxxxxxxxxxxx [mailto:nswnra-bounce@xxxxxxxxxxxxx] On Behalf Of Paul McGuiness Sent: Thursday, 12 August 2010 10:57 To: nswnra@xxxxxxxxxxxxx Subject: [nswnra] Re: Helix Nebula Hi Rob, That looks pretty good, tracking seems OK.There seems to be a bit of what I suppose is"digital noise" - if that's the right term -in the background. Just need a minus10 degree refrigeration unit - just joking. Well done.Beware the lure of the Dark Side ..... Cheers, Paul.

So that night I thought I might throw the camera on it and try a bit of imagining. But by evening it started raining so the mount got covered and sat there for afew days. Last night it amazingly cleared up beautifully but then the dangneighbour (not Vince) lit a fire to burn off some rubbish after dark sendingsmoke right across my yard Grrrrr!!!! which eventually died down later. Anyways I managed my first ever DSO image, a series of 10 x 2 minute exposures of the Helix. Not the greatest but I was pretty happy how it turned out. Took a bunch of SMC but once I got them on the lappy the focus was out. hope you all are keeping dry.
