M104 / NGC 4594 is a peculiar galaxy of unclear classification. M104’s diameter is 50,000 Ly about 1/3 the size of our own Milky Way. This Galaxy is 31.1 Mly from earth, shinning at magnitude 8. It reside in the constellation of Virgo, near Corvus. M104 has many globular clusters, estimated to be nearly 2,000 in number — 10 times more than the number of globular clusters in our Milky Way galaxy.
M 1o4’s core is very illuminated, where a one-billion-solar-mass black hole resides. This galaxy has an estimated mass of 800 billion stars similar to our own sun. M104 is one of the most massive objects in the Virgo galaxy cluster.
M 104 was discovered on May 11, 1781 by Pierre Méchain,
Charles Messier made a hand-written note about this and five other objects (now collectively recognized as M104 – M109) to his personal list of objects now known as the Messier Catalogue. It was not included until 1921 about the 10 years after Mt. Wilson’s 100” telescope was up and running (1917)
M109 /NGC 3992 Barred Spiral Galaxy approximately 83 million light years from Earth located in the Constellation URSA Major (Big Dipper). (location is 11:57.6 (R.A.) and +53:23 (Dec.). This barred spiral galaxy is readily visible through telescopes of 6″ aperture or better. Really looks good in 10″ telescopes at a Dark Sky site. When looking at the M109 /NGC 3992 Barred Spiral Galaxy, remember it is approximately 175,853.82 light years in diameter. (Milky Way is 100,000). M 109’s apparent Magnitude of 10.6 and size 7.6′ x 4.7′ (arc-minute)
The Messier objects were M 1-M 103 discovered and named by Charles Messier (see )until after the fifties when M 104-M 110 were added. M 109 is listed in The New General Catalog it is listed as NGC 3992.
This image was capture through a 5.5″ f/7 TEC refractor using a CCD with KAF 3200me chip cooled to -20c, each exposure was 5 min long 3 for each color channel (RGB) the rest were luminous.
1st Quarter Moon video, using different cameras and telescopes. Staring from view of entire 1st quarter as seen through binoculars (7x) and ending in a zoomed in view of craters Theophilus (Top) Cyrillus (Middle) Catharina (Bottom). Theophilus is the most prominent and youngest crater,62.14 miles in diameter and 2 miles deep with a central peak of 2.74 miles. The other two craters are much older and more worn, Catharina is 62 miles in diameter and 1.92 miles deep; Cyrillus is 98 km in diameter and only 1.92 miles deep.
