B&W universe, part I


As I'm using a cooled Gray scale astronomical CCD camera, I have a Black and White images from all of my photos. (For a color image, colors are made by shooting each color channel trough a filter, in my case mostly a narrow band filters.)

I will publish few posts out of my B&W images. Sometimes I like them better as a color ones.
