Let's see, to double the signal to noise ratio you'd need another 124
hours. Least I'd think the square law would apply here. Now the connection between the main nebula and the red blob on the left is starting to show. I was wondering if they were even related. Appears they are.

You'll end up in the Guinness book of records if you don't stop now ;-)
I wonder if there is a practical limit to "useful" exposure times. Adding some more hours certainly improved the image, but would e.g. 80 hours be noticeably better than 60 hours? Maybe you will show us ;-) Stefan "Richard Crisp" schrieb im Newsbeitrag ... looking a bit better now that the halpha is up to 14 hours now at 31 hours total (62 x 30 minutes overall) http://www.narrowbandimaging.com/jon...ao3o3_page.htm |

Or it may be time to order that 36-inch scope and liquid nitrogen cooled back-lit camera! Of course the results you have are spectacular and really tell the story of this nebula. George N |
