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 it didn’t set until about 10:30 pm, so about half of the 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 Adobe 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!

Nice images! I am considering the purchase of the ES 80mm triplet ED(now $649) and it is difficult to find any published images. Your images have helped me out. Buy! Thanks for sharing…
You're Welcome! I can highly recommend the ES 80ED Triplet… It is so small and easy to set up. and is capable of capturing amazing images!
Hey Trevor, Another beautiful shot! The "contrast enhancement" brings out the structure really nice… You're so right, I have an old set of "Astronomy Tools" for photoshop 4 and they rock!
Incredible shot with a stock 450d! I also have a Canon 450d (mine is modded) and I am attempting this target soon in this winter. How would you advise on the ISO setting?
A lot of people recommend going with ISO 800 but you did amazing work with 1600. What’s your opinion about it on 450d?
Thank you so much in advance!
Hello from the future and congratulations on a nice image!
I’m in an Ottawa suburb, Clearsky says Bortle 6 so not too different from you and my scope is f/6. If i exposed for 200+ seconds at ISO 1600 I think the histogram would be pinned at the right side. Am I missing something?
I have been thinking of shooting this with my unmodified t7i and redcat51. I don’t have a goto mount quite yet so I do rely on test exposures to make sure I have my target in my sights. Are you able to see any of the details on this object in the previews or should I wait for my asiair so that I can stretch on the go to make sure?
you could try it, I think you’d be looking for star patterns rather than the nebulosity – that would be tough to see in a single sub. Would you be able to run plate solving on it? If you can upload a jpg to astrometry.net that will annotate it for you.
Was there any light pollution filter used here?
