Andromeda Galaxy

Photographing the Andromeda Galaxy

|Galaxies|16 Comments

With summer coming to a close, I had one last chance for some deep sky astrophotography under dark skies.  Choosing an astrophotography target at a dark sky site requires some serious thought. The key is to focus on an object that will benefit from broadband color data without the need for harsh light pollution filters. After much deliberation, I decided to spend this rare occasion with my sights set on the Andromeda Galaxy. Cataloged as Messier 31, Andromeda is a massive spiral galaxy that demands attention. This month, it's well placed in the night sky for your next astrophotography proj…

Narrowband Images with a Color Camera

|Narrowband|15 Comments

My latest encounters capturing narrowband images with a color camera have once again opened my eyes to a new level of astrophotography possibilities. In this post, I'll share my results using a color CMOS sensor camera. In the past, I found that by collecting narrowband data such as H-Alpha with a DSLR, you can complement your broadband (true color RGB) astrophotography.  This is great news for DSLR astrophotographers that want to amplify their deep sky imaging. Narrowband Astrophotography Filters The ongoing learning curve involved with astrophotography continues to provide me with…
