I missed my opportunity to image comet PANSTARRS back during it’s brightest and closest approach in March of 2013 when it was a magnitude of 1, but since then it has been making it’s way north I still had the opportunity to catch it through the telescope. As it has been making it’s journey it has diminished in magnitude as it travels away from the Sun. At the time I imaged the comet it was roughly at magnitude 9.3 which is too dim to see with the unaided eye, but visible through a telescope of medium size. Located in the constellation of Ursa Minor, or Little Dipper, just outside of the bowl of the dipper.

In this image of PANSTARRS it was 2.06AU from the Sun, and about 2.03AU from Earth. This image is comprised of 80 images at 35 seconds a piece with about 40 dark frames to remove noise. It is a combination of two stacks done within Deep Sky Stacker, one stacking just the comet, and the other stacking just the stars. Processed in Photoshop to bring out the comet, and to combine the two stacks into a final image.
