sorry for the ccd shot, it is all I have to share today :-(
 
 
This is my first attempt at a color mosaic. I shot the Rosette Nebula through [SII], Ha and [OIII] filters on Friday night.
 
I am still working on gathering more data, this is only two hours, 20 minutes for each filter at each of two sites for a total of 6 exposures of 20 minutes.
 
Since there is only one shot through each filter, the signal is noisier than I'd like but that should improve when I can gather more data.
 
Here is the image:

If the green/blue turns you off, let me call your attention to this:

Earlier in the summer I attempted the same object:

Mike Cook helped make it even better by combing my color with Stan Moore's Luminance (Red) data. That work of Mike/Stan is also on the linked page above (thanks Mike and Stan!)
 
Anyway Green/Blue is where the action is in the star forming nebulae!
