11" SCT f/6.4 and STF-8300M CCD Camera


Comet 45P approached and passed the background Comet 158P on the nights of May 24 & 25 as seen from the night skies of Denver. Unfortunately, it was daylight in Denver when 45P was just 0.017 degrees from 158P with 158P undoubtedly in the dusty glow of 45P. This mosaic of the images from the 2 consecutive nights is not very pretty until one realizes both comets are about magnitude 20 and the individual images stacked on comet 158P are a combined 110 minutes (May 24) and 80 minutes (May25) taken from the light polluted skies of Denver with only an 11" SCT. The comets were about 0.1 degree apart on both nights. 158P has a well defined nucleus while 45P has become a dusty glow with a hard to find nucleus on images that are stacked on 45P.
