11" SCT f/6.4 and STF-8300M CCD Camera
Asteroid 2014 JO25 is now 29 million miles from Earth and has dimmed to magnitude 16.6. Spiral Galaxy NGC 4177 is in the background as JO25 passes it. Unfortunately the 3/4 illuminated Moon was only 29 degrees away which washed out some of the galaxies features. The insets are 12 images (each 5 minutes) tracked on the asteroid which is circled.

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. Unfortunately, the constant spraying of Chem Trails over Denver has turned the Denver Front Range into a cloudy dry desert. 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.
