LDN 673 Dark Nebula in Aquila LDN 673 Dark nebula in Aquila.  LDN 673 is an interesting collection of dust and gas in the constellation Aquila.  It is one of the many dark nebulae catalogued by Beverly Lynds in 1962.  Because it lies near the plane of the Milky Way, it blocks out light from the rich star field behind it, offering a ghostlike appearance.  Two bright nebulae sit in the dark cloud (RNO 109 near the bright star at the top and Herbig-Haro 32 just below center). The dark cloud is about 600 light-years distant and extends over 10 light-years.   Additional images can be found here and here.
This image is an LRGB composite of 300:100:100:100  (10 hours total exposure) made from June 17- 19, 2017, 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 CCD Commander and 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.
