There is little visible DIGITAL NOISE here. I have charted the stars and most are on chart. The bluing was added to minimize gray noise. Shot in B&W mode with Red built in filtration. 20 sec. exposure at f:/2.8. There is one faint meterorite from the Perseid Shower. Shot at approximately 1:00 a.m. EDT on 12 August 2008. Careful post-shoot treatment in Adobe Lightroom and CS2 to reduce LARGE file size and minimize noise scattering in viewing enlarged. The meteorite is located almost direct above the "V" opening, between trees on the bottom of the image. Enjoy.
