M100 Widefield

< Previous Next >While the actual target was M100 and its latest Supernova I was surprised how many faint fuzzies there were in the image. M100 is the brightest member of the massive Virgo cluster of galaxies. I also made an overlay map of the field identifying the objects at least somehow visible in the image. I did have severe problems with noise and light pollution in this image, so the dimmest galaxies are really dim in this image also. Take a look at the original resolution image which has original aspect ratio also. The original version here is 2x scaled down from the master image from the camera (too big for a web page).
