Grayscale Wonders part IV

All the photos, I have published, are taken with a grayscale astronomical camera. Each color channel is shot separately and then combined to RGB color image. Since I'm doing only narrowband imaging due the extensive light pollution color channels are are emission line images. Most of the time I'm capturing three emission lines hydrogen, sulfur and oxygen. (H-alpha, S-II and O-III)

Usually most of the details are in hydrogen alpha emission line. Gray scale images can be really beautiful and many times I personally like them best. I will publish now some of my images from this winter season as a grayscale compositions. This is a part IV of Grayscale Wonders, part one, two and three can be seen here: Part one,
Part two,
Part three,

Please, open the full size photo by clicking the image, it's really worth it!
