Description

Crescent nebula with a one shot color camera is a real challenge.

Beside the lack of HA, you end up with an image with "an excessive number" of stars.

So it took time to process the data, and i'm not sure i did the right thing to control all of thoses moskitoes in the final image

I will appreciate your comments on this more than 10 hours shot.

On the 2 last versions, i add 3 hours of the data from the STC dual narrowband filter.

Now, with good eyes you can spot the Planetary Nebula (NP G75.5 1.7) discover in 2010 by Dave Jurasevich alias the soap bubble ;)
