Hi all, it was a while I wanted to shoot the Helix nebula from Coona. Considering that with my rig I cannot get a very high resolution (my scope is only 1 mt FL) I tried to go deep to see what I was able to see on the faintest parts of this planetary. I was pleased to detect the large bubble gas that envelopes the main ring and also some dust in the area, even if I was a bit surprised by how faint these features are and how much I had to stretch the original data to make them visible.
Here is the link:

Total exposure was 16.5 hours (HaOIIILRGB). Other details on the page.
As usual there is also a the full res zoomify version accessible here:

Hope you will like it.
