The Horsehead Nebula (aka Barnard 33) - this target is one I've been going after for about 2 years now - and for whatever reason, it's evaded me at this magnification for a while now. Finding enough time to get the big scope at [url=
https://www.facebook.com/WAS.CT/?__cft__[0]Westport Astronomical Society[/url] on the target was challenging for some reason. This weekend, the entire imaging team was out on Friday, and I had the big scope to myself last night... so I put 44 frames @ 180s (3 min each) on this rather difficult target. And voila! I don't say this too often, but this turned out sweet!
From Wikipedia: The
Horsehead Nebula (also known as
Barnard 33) is a small
dark nebula in the constellation
Orion.
[2] The nebula is located just to the south of
Alnitak, the easternmost star of
Orion's Belt, and is part of the much larger
Orion Molecular Cloud Complex. It appears within the southern region of the dense dust cloud known as Lynds 1630, along the edge of the much larger, active star-forming
H II region called
IC 434.
[3]The Horsehead Nebula is approximately 422 parsecs or 1,375
light-years from Earth.
[1][3] It is one of the most identifiable nebulae because of its resemblance to a
horse's head.
