Winter Messier List Observing Club
Winter Messier List Observing Club Raleigh Astronomy Club Version 1.1 24 November 2012 Introduction Welcome to the Winter Messier List Observing Club. The objects on this list represent many of the most prominent deep sky objects (Globular Clusters, Open Clusters, Nebula, Galaxies) visible from mid-northern latitudes. The Messier list of objects was compiled in the 1700’s by the French comet hunter Charles Messier and his associates as a list of objects to not confuse with their primary goal of discovering new comets. What they really produced, was a list of many of the best deep sky objects for astronomers to enjoy. Observing the Messier List is an excellent way for beginning astronomers to learn the night sky. This club is intended for those who wish to tour the Messier objects while adding more structure to their observing activities. Club members who wish to work their way through the Messier objects, a season at a time, will find this list to be a helpful guide. Two certificate levels are offered, Silver and Gold. The Silver certificate is earned by viewing and logging all objects on the list while using Go-To or Digital Setting Circles to help locate the Messier objects. The Gold certificate is earned by those who view and log all the objects while only using charts and star hopping to locate them. Anyone who intends to use their RAC list results as a stepping-stone to the Astronomlcal League Messier certificate, MUST work to the Gold certificate rules. Rules To earn the Winter Messier List certificate, you must: 1. -

Messier Objects
Messier Objects From the Stocker Astroscience Center at Florida International University Miami Florida The Messier Project Main contributors: • Daniel Puentes • Steven Revesz • Bobby Martinez Charles Messier • Gabriel Salazar • Riya Gandhi • Dr. James Webb – Director, Stocker Astroscience center • All images reduced and combined using MIRA image processing software. (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. -

Not one star in the image can be seen by the naked eye. 4. Color of star reflects its surface temperature. Eagle Nebula. M 16 1. Messier 16 is a conspicuous region of active star formation, appearing in the constellation Serpens Cauda. This giant cloud of interstellar gas and dust is commonly known as the Eagle Nebula, and has already created a cluster of young stars. The nebula is also referred to the Star Queen Nebula and as IC 4703; the cluster is NGC 6611. With an overall visual magnitude of 6.4, and an apparent diameter of 7', the Eagle Nebula's star cluster is best seen with low power telescopes. The brightest star in the cluster has an apparent magnitude of +8.24, easily visible with good binoculars. A 4" scope reveals about 20 stars in an uneven background of fainter stars and nebulosity; three nebulous concentrations can be glimpsed under good conditions. Under very good conditions, suggestions of dark obscuring matter can be seen to the north of the cluster. In an 8" telescope at low power, M 16 is an impressive object. The nebula extends much farther out, to a diameter of over 30'. It is filled with dark regions and globules, including a peculiar dark column and a luminous rim around the cluster. -
A Basic Requirement for Studying the Heavens Is Determining Where In
Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short). -

The Messier Objects
WHAT’S IN The Messier Objects THE NIGHT SKY? Bonus Material The Messier objects are a list of 110 deep-sky objects that were catalogued by a French astronomer called Charles Messier. He created this list in the 1700’s when he was looking for comets. He wanted to keep track of the things he could see in the night sky, so he wouldn’t confuse them for comets. The Messier objects all have names that start with the letter M (for Messier), followed by a number. For example, M13 is a Messier object which can be found in the Hercules constellation. Types of Messier objects Globular Clusters – These are spherical Supernova Remnants – When a very large (round) systems of ancient stars held together star (more than 5 times the size of our Sun) by gravity.

(In this case, I'm I find it somewhat reminiscent of South Park's Planetarium Episode - some of you out there may know what I'm talking about, the rest feel free to ignore me and continue on.) Personally, I've always seen the major stars as a Teapot, with the Milky Way curling up and out of the spout - cosmic steam if you will.
