Two years of NGC6888
|
|
This is an interesting one. I shot the Crescent Nebula a few days ago (7-26-2011). I used a 10 minute exposure and got good results with the nebula but poor stars for some reason. I remembered that I shot this same object two years ago (9-18-2009). At that time I was using 5 minute exposures and did not get near as much of this dim nebula. Using Photoshop I was able to combine these images using the 2009 12 X 300 second exposures for the nice stars and the 2011 10 X 600 second exposures for the nebula.
