11" SC Telescope and STF-8300M CCD Camera
Comet 226P passed Comet C/2010 U3 over the next few days after these images were taken. Both comets were moving east and both comets were magnitude 18. The big image is a mosaic of 2 images. The insets attempt to show the comets a little better than the bigger image. The comets were 3/4 of a degree apart in this 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 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 "".
