Photographer
Mike Olason
Location of photo
Denver Colorado
Date/Time of photo
2016/12/21 0108UT
Equipment
66mm Refractor f/6 Telescope and ST-402 CCD Camera
Description
Comet 45P will brighten to Magnitude 6? on February 11 when it will pass about 8 million miles from Earth in our morning sky. Unfortunately there will be a full Moon, but binoculars might show a nice comet with a long tail 50 degrees above the eastern horizon at 4AM. The images were taken at the end of dusk with the comet 9 degrees above the southwest skies of Denver as it was getting ready to set. The mono image shows a magnitude 10 comet with a faint, narrow tail 1/2 degree long. The tail was not visible in the color image.

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.
