B72 Dark nebula  B72 Dark nebula (Snake Nebula) in Opiuchus. Barnard 72 is one of many dark nebulae cataloged by the famous astronomer E.E. Barnard. Dark nebulae are typically clouds of dust or gas in our own galaxy that obstruct the stars lying behind them. Barnard's final catalog contained some 369 objects. The most famous of Barnard's nebulae is B33, the Horsehead Nebula in Orion. The Snake Nebula is pretty obvious but several other Barnard objects lie in the same field. For some more dark nebula see my images of B64 & 259, LDN 935, B142-143, B347, B145 and B173-174.
This image is an LRGB composite of 60:60:60:60 minutes made on June 1-2, 2016, from my remote observatory in Animas, New Mexico.  I used an SBIG STL11000M camera and an ASA 10N astrograph to record the image. The data was acquired and assembled using MaximDL with final processing done in  Photoshop

This page illustrates what can be photographed using amateur telescopes and a CCD camera.  I currently use an SBIG STL11000M camera and have previously used SBIG and Starlight Xpress cameras, as well as a Cookbook 245 camera that I built myself.  Most of the images in this web site were taken from my backyard near a busy street with several street lights.  Not only is the CCD camera a great imaging tool, but it allows "real time" observation of objects not normally visible in areas with moderate-severe light pollution.
