Description
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 about magnitude 20.5. My images are not pretty, they have only been dark subtracted, flat fielded, contrast/brightness adjusted and maybe a median filter to reduce the image noise. This is all done with the camera software CCDOps. The comet images reflect reality, not photographic artistry.
