I had an unexpected clear night recently. So I decided to take the Astronomik Ha 12nm Clip In Filter for a
road sky space test. Pointing the telescope towards Orion, I decided to begin gathering data on The Horsehead Nebula.
The Horsehead Nebula
Otherwise known as Barnard 33, this dark nebula gets its name by the striking resemblance to that of a horse’s head. Often (almost always) photographed with it is the reflection nebula NGC 2023. The Horsehead Nebula is a popular winter time target and as such the perfect time to photograph it is late November to January.
I was able to capture this wavelength due to the generosity of The Widescreen Centre in loaning me the filter for review. The Astronomik 12nm Hydrogen Alpha Clip-In Filter is a heavy weight filter known for being really useful and good with DSLR cameras. So it was perfect for me and my modified Canon 600D.
