A Neighbor of Ours ... Messier 33 The Triangulum Galaxy
The Triangulum Galaxy is a spiral galaxy 2.73 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye.
The galaxy is the smallest spiral galaxy in the Local Group and is believed to be a satellite of the Andromeda Galaxy or on its rebound into the latter due to their interactions, velocities, and proximity to one another in the night sky. It also has an H II nucleus. (Wikipedia.org)
Technical Info for Image: This image was taken with my Explore Scientific ED102 APO f7, FL 714mm, refractor telescope mounted on a Celestron Advanced VX Equatorial Mount. A ZWO ASI294MC Pro camera was attached to the prime focus of the telescope and cooled to -5C while set to a Gain of 120. An Orion 50mm guide scope (FL 242mm) was connected to a ZWO ASI290MC camera which communicated with PHD2 auto-guiding software to give precision guiding to the rig as the stars marched across the heavens. 18 images of 120 seconds each were taken at Bin 2x2. Image acquisition was through Astrophotography Tool (APT) software. Post processing and editing were done with Pixinsight software. Polar alignment was done with SharpCap Pro. Final touchup of the image and translation into the JPG format was done with Adobe Photoshop Creative Cloud software prior to uploading to Flickr. This sequence, was taken under the excellent dark skies of Landers, California USA at the time of a new moon so the stars were shining brightly.
