Description
Comet C/2016 N4 Master on it's 3rd night crossing the background glow of the Andromeda Galaxy is in the western region of M31 just above the double nucleus at the center of M31. The Andromeda Galaxy is the largest galaxy in our local group with about one trillion stars. In about 4.5 billion years our Milky Way Galaxy and the Andromeda Galaxy are expected to collide and merge. The inset attempts to show the comet a little better.

About Mike Olason

I started imaging comets in 1994 with an ST-5 CCD Camera and an 11" SC Telescope. Since then the CCD cameras have changed (ST-7, ST-402ME and STF-8300M), but I am still using the 11" SC Telescope. Naturally I have used a lot of smaller telescopes to obtain larger fields of view. I live south of Denver at an elevation of 6150 feet which allows me to image comets down to almost magnitude 21 on a perfect night. Unfortunately ChemTrails have turned Denver cloudy and dry. I use the camera software CCDOps to process my images. All I do to each image is dark subtraction and flat field, stack images as required to show faint comets, contrast/bright adjust the final image and maybe use a median filter to reduce the image noise. The result is an image that reflects reality and will never win any picture of the day award. If you would like to use my images for a project or ask a question send me an email to "moicylander@centurylink.net".
