James Cahill is an IT specialist by day, amateur astronomer & Astrophotographer at night. His work is shot primarily in Bucks County, PA but he also visits dark sky areas in Maine, Pennsylvania & other states on the east coast. His work in astrophotography ranges in nearby solar system objects, deep sky objects & wide field shots of our own galactic home, the Milky Way. James has just recently joined the community of Astrophotographers, starting to photograph his targets within the past 6 years.

James started with a webcam, imaging the Moon & planets. After that, he was hooked, adding equipment to start taking pictures of further away objects like nebulae, galaxies & star clusters. Pairing a digital camera & using the telescope as a "lens" has enabled him to take pictures of what has always been his passion, the night sky.

James recently received the patron’s award from judge Emmet Gowin for the 2020 Phillips Mill Photography Exhibition, in New Hope, Pennsylvania.
