Magnitude 17 Comet C/2014 W2 Panstarrs is passing about 1/2 degree from the background Globular Cluster M107 which is magnitude 8. The comet is 382 Million miles from Earth while M107 is 20,900 light-years (1 light-year is 5.9 Trillion miles) from Earth. The inset with the comet in the center attempts to show the comet a little better. The comet has no apparent tail in this image but does show a coma around the nucleus.

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 "".
