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.
