St. Petersburg Astronomy Club Examiner December 2020 President’s Message As 2020 comes to a close, and we peer back at the year, you realize it’s better to look forward and not dwell on the past. The first couple of months were, for the most part, normal. OBS 2020 was a success, thanks to Mike Partain and our volunteers. Then, everything changed. All of our outreach activities had been put on hold. We moved our general meetings on-line, to avoid in person group meetings. The 2021 Annual Star Party was canceled and replaced with a New Moon Super Weekend. In spite of the pandemic, interest in astronomy and the club has grown. More people are showing up to the new moon weekends. On average, we are adding new members every month. As we move into 2021, and life begins to slowly move back to a sense of normality, the club will pick up the projects that were put on hold during 2020. Until then, from my family to yours, have a Safe and Happy Holidays! Clear skies. Brad Perryman December General Meeting The club’s next New Moon observing weekend will be held December 11th-13th This month’s general meeting will take at Withlacoochee River Park. January’s place on Friday, December 18th at 8:00 observing weekend will be the 8th-10th. PM. The main program will be by Tom Field, who will be presenting, “Spectroscopy for Everyone with Rspec Software.” This meeting will be held virtually with GoToMeeting.com.

(Mirametrics) What are Messier Objects? • Messier objects are a list of astronomical sources compiled by Charles Messier, an 18th and early 19th century astronomer. He created a list of distracting objects to avoid while comet hunting. This list now contains over 110 objects, many of which are the most famous astronomical bodies known. The list contains planetary nebula, star clusters, and other galaxies. - Bobby Martinez The Telescope The telescope used to take these images is an Astronomical Consultants and Equipment (ACE) 24- inch (0.61-meter) Ritchey-Chretien reflecting telescope. It has a focal ratio of F6.2 and is supported on a structure independent of the building that houses it. It is equipped with a Finger Lakes 1kx1k CCD camera cooled to -30o C at the Cassegrain focus. It is equipped with dual filter wheels, the first containing UBVRI scientific filters and the second RGBL color filters. Messier 1 Found 6,500 light years away in the constellation of Taurus, the Crab Nebula (known as M1) is a supernova remnant. The original supernova that formed the crab nebula was observed by Chinese, Japanese and Arab astronomers in 1054 AD as an incredibly bright “Guest star” which was visible for over twenty-two months. The supernova that produced the Crab Nebula is thought to have been an evolved star roughly ten times more massive than the Sun.

  • Open Clusters
    Open Clusters Open clusters (also known as galactic clusters) are of tremendous importance to the science of astronomy, if not to astrophysics and cosmology generally. Star clusters serve as the "laboratories" of astronomy, with stars now all at nearly the same distance and all created at essentially the same time. Each cluster thus is a running experiment, where we can observe the effects of composition, age, and environment. We are hobbled by seeing only a snapshot in time of each cluster, but taken collectively we can understand their evolution, and that of their included stars. These clusters are also important tracers of the Milky Way and other parent galaxies. They help us to understand their current structure and derive theories of the creation and evolution of galaxies. Just as importantly, starting from just the Hyades and the Pleiades, and then going to more distance clusters, open clusters serve to define the distance scale of the Milky Way, and from there all other galaxies and the entire universe. However, there is far more to the study of star clusters than that. Anyone who has looked at a cluster through a telescope or binoculars has realized that these are objects of immense beauty and symmetry. Whether a cluster like the Pleiades seen with delicate beauty with the unaided eye or in a small telescope or binoculars, or a cluster like NGC 7789 whose thousands of stars are seen with overpowering wonder in a large telescope, open clusters can only bring awe and amazement to the viewer. These sights are available to all.

  • Just What Are Those Sky Chart "M" and "NGC" Numbers? by Barry D
    Just what are those Sky Chart "M" and "NGC" Numbers? By Barry D. Malpas – Special to the Williams-Grand Canyon News – 2014 November One of the pastimes for some early sky observers was to locate new comets. Charles Messier (1730-1817) was a French comet hunter during the late 1700s, and discovered 13 new comets between 1760 and 1785. His interest in astronomy, and comets in particular, was influenced by seeing the great comet of 1744, and the comet of 1759 (of which Edmond Halley had believed the comets of 1531, 1607, and 1682 were the same and had predicted the comet’s 1759 apparition which is now known as Halley's Comet.) At this time telescopes were relatively small. The understanding of supernovae, or galaxies, was not yet in the current knowledge, as such objects only appeared as blurry smudges that did not move across the sky. In order not to waste time and become frustrated with viewing fuzzy objects that resembled, but were not, comets, Messier compiled a list of 110 of these celestial blurs which we now refer to as Messier, or "M Objects." The Messier Catalog has become a very popular list of "Deep Sky Objects" among amateur astronomers around the world because it consists of most of the galaxies, nebulae and star clusters easily observable with binoculars or small telescopes in the northern skies. Now, however, the objects in the list are the source of interest, as opposed to the reason the compilation was originally intended by Messier. At large astronomical get-togethers, known as "star parties", there is often a "Messier Marathon" competition to view the most Messier Objects during one observing night.
