Description
Magnitude 17 comet P/2015 TP200 Linear is passing three magnitude 15 edge-on spiral galaxies. The comet has a fan shaped tail that unfortunately is pointing directly at the star below it in this image. As usual it is hard to bring out the details of the galaxies and still show the fainter moving comet in the same image. The inset attempts to show the comet 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 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.
