Rosette Nebula – Stock Canon DSLR

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.

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!

Pacman Nebula – Stock Canon DSLR

|Nebulae|0 Comments

Below, you will see an image of the Pacman Nebula using a stock (non-modified) DSLR camera. A Canon EOS Rebel Xsi (450D) to be exact. I have often said that an entry-level DSLR camera is probably the best astrophotography camera to start out with.

DSLR cameras are affordable, versatile, and can be used for more than just astrophotography at night. They are also more user-friendly and don’t require additional software tools to use. The deep sky image below is an example of what you can expect to capture through a telescope without an astro-modification. Further down the page, I’ll show you what this nebula looks like using a dedicated astronomy camera and narrowband filters.

This is a great time of year for astrophotography, with the nights beginning so early and lasting so long. The downside, of course, is the frigid temperatures. Luckily I have a reasonable winter setup for imaging that includes a small space heater and a lot of warm clothing. I am able to enter a small shed and hang out while my camera fires away. The temperature dropped to -3 on Sunday night, great for imaging.

I have never shot the Pacman Nebula before. To be honest, I had no idea a stock DLSR could pick up so much red in this object. Cassiopeia rises nice and high in the evening this time of year, so imaging NGC 281 is a popular target right now. I am very happy with the way this DSO has turned out so far, even with the limited time I have put on it. I was also surprised at its size, comparable to the Eagle Nebula in my 80mm scope.

My latest photograph of this nebula was taken using an Altair Hypercam 183C color CMOS camera. I captured broadband RGB light frames on this target using a 2″ Baader Moon and Skyglow (Neodymium) filter. To add a boost in signal, I also captured images with a 12nm Ha filter and combined the two using the HaRGB method.
