Notes: * This little galaxy was imaged while I was waiting for the moon to clear the area of NGC 2371/72. I had to image down to about ~20 degrees above the western horizon, in order to get enough time in. Also, the entire three days had varying amounts of high clouds (the story of this winter), which along with the full moon, made the background very hard to process.
