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.

Caldwell 49 – The Rosette Nebula
Imaged Monday, February 3, 2014

38 subs, 3.5 Minutes Each totaling 2 Hours 13 Minutes

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!
