Description
Comet 41P is 1/4 degree from the background spiral galaxy NGC 6015. The comet is about magnitude 7 and the galaxy is magnitude 11.7. The color image is 1 degree by 1 degree with the stars showing as short red, multi color and blue streaks even in this short 6 minutes of RGB images due to the comet moving almost 2 degrees per day across our skies. The only way to take images longer than a few minutes of comets moving this fast and not show star movement is to remove the comet from the streaked star field of the original image and insert the comet back into a static star field using photographic artistry. Makes for a nice image but does not reflect reality.

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 on a clear night. I give permission to anyone who may want to use my images for a project or article, especially school projects. All that I ask is that if you use some of my images that you give me credit for taking the images. I have 1000s of comet images so if you would like more images of the same comet on a different date, other comets or would like to ask a question about one of my comet images send me an email to "moicylander@centurylink.net".
