The Essential Guide to Astronomy

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 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 filter to reduce the image noise. The result is an image that reflects reality and will never win any picture of the day award. You may use my images for a project, if you would like to ask a question send me an email to "[email protected]".
