1" Refractor Finderscope and ST-402ME CCD Camera
Magnitude 10 Comet C/2017 E4 Lovejoy is only 5 degrees from the 23% illuminated Moon in this image. The Moon's glare shows up as different shades of red, green and blue in the image as its reflections are seen from different atmospheric conditions (thin clouds, pollution, etc) during the collection of each separate red, green and blue image which are combined to make 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.
