|Bubble nebula using the Hubble palette. Total exposure time is 33 hours.|
The seeing in this image is ~3.2". It would have been nice to have 2" instead! I have not fallen for the temptation of sharpening and I don't think it would help much.
Earlier today I sent the narrowband images to my good friend, Henrik Bondo, who will attempt to process them into something that has more natural looking colors. So, for many reasons the image shown here is not the final one, after all. We can keep on working on our projects forever - and that's OK!

After midnight the target was M100 in green light - haze seemed to be less severe then. Comparing to red light data from a few weeks ago with no moon and less haze suggested the images to be of reasonable quality, but not as good. The background ADU was around 2000, compared to ~1000 earlier. I'll do a critical comparison with future M100 green images to find out if last nights run is useful at all - I am not too optimistic!
