Location of photo
Denver, Colorado

Equipment
11" SCT f/4.6 and STF-8300M CCD Camera
Description
In this image Comet C/2018 L2 ATLAS is only 8 degrees above the southern horizon. The comet is a relatively bright magnitude 16 but smoky skies at this low altitude do not make for a very impressive image of the comet from Denver. C/2018 L2 will make its close approach to the Earth on June 17 when it will be 181 million miles from Earth. The comet does not reach perihelion until December 2 when it will be about 160 million miles from the Sun and at about an expected peak magnitude of 14.

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".
