This photo was taken on Mar. 25th from a vacant lot in Tucson AZ. It is composed of 33-3 min. exposures. A Baader UHC-S filter was used. It was a cloudless night but the seeing and transparency conditions were poor. The moon was waxing gibbous 82% full! This is the beauty of CCD photography - an image is possible when you can't see anything through the eye piece.The Pin Wheel Galaxy is a spiral galaxy in Ursa Major and is about 27 million ly from Earth. It has a linear diameter of about 170,000 ly. The image field is about 40 arc min. wide.
