Description

Pinwheel Galaxy M101 is my first RGB astrophotography with my recently acquired telescope TEC 160FL. This galaxy fits my telescope FOV. Due to the heavy light pollution in my backyard with two street lights, the Lum subframes looked unacceptable from my point of view. I decided to just use RGB subframes to integrate this image.
