NGC 7293 Helix Nebula in Aquarius  NGC 7293 Planetary nebula in Aquarius (Helix nebula). The Helix Nebula is the largest "planetary" nebula visible in small telescopes.  It lies at a distance of about 650-700 light-years, making it one of the nearest deep space objects to our solar system.  The name Helix derives from its apparent shape from our vantage point. The Helix has been imaged in multiple wavelengths by different systems: Hubble (visible), Spitzer and Galex (ultraviolet and infrared), and ESO Vista (infrared). For more information about NGC 7293, see the APOD 10/12/2014.
This image is an LHαRGB composite of 280:120:90:90:90 minutes made from August 30 to September 6, 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 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.
