How the Rosette Nebula looks with a Stock DSLR
Will an unmodified Canon DSLR pick up the red nebulosity?
Happy New Year! I was finally graced with some clear skies that showcased the beautiful winter milky way on Monday. The moon was about 19% lit, and didn’t set until about 10:30pm, so about half of data in the photo above was captured with the moon still out. The sky conditions were so fantastic on Monday, it was a shame I had to leave early to get a good night’s sleep for work the next morning.
The Rosette Nebula (Caldwell 49) is a large circular HII region. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula’s matter.

I used the Explore Scientific 80ED telescope for this photo because the size of this object is quite large. I am quite happy with my end result, although I plan on processing the photo several more times to try and pull out as much detail as possible.
I highly recommend Noel Caboni’s “Astronomy Tools” action set for Photoshop. I found it very helpful when processing this image, and every other image I have taken. For the price of a cheap filter, you can drastically improve your astrophotos. Well worth it!
