Hi all,

When I posted my Thor's Helmet nebula a couple of weeks ago, I was really happy with the result, but wanted to see if more integration would make a significant improvement to the overall image. My image had an integration of 3h10' and I have now added data to give an overall integration of 10h. I actually had about 12 hours, but threw away a couple of dozen of subs with bad focus or eccentricity... I think I really like the image with more integration. There is certainly more detail. I have posted the two editions of the new image on the left, and re-posted the old image on the right for comparison.

As usual, please feel free to provide feedback so that I can improve my imaging and processing skills.

Clear skies,
Stéphane
