It has taken quite some time to get around to imaging this object and I am glad it has now almost been completed. This image is of M20 with narrow band and broad band data. For the traditionalist I plan on collecting a bit more data in RGB to provide a traditional view of this object. For now though this is the image I had originally planned when I began this project earlier in the year. I hope people like it as much as I do. Please feel free to tell you what you like or don't like about the image.
The image contains the following data:
Luminance 120 minutes
Red 60 minutes
Green 20 minutes
Blue 20 minutes
SII 210 minutes
Ha 360 minutes
OIII 210 minutes
Total at this stage being 16.7 hours.
