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. -

TAAS Observing Challenge, March 2016 Deep Sky Object
TAAS Observing Challenge, March 2016 Deep Sky Object NGC 3242 (PN) Hydra ra: 10h 24m 46.2s dec: -18° 38’ 34” Magnitude (visual) = 7.7 Size = 64” Distance = approximately 2,500 light years Description: William Herschel discovered this planetary nebula on February 7, 1785, and cataloged it as H IV.27. John Herschel observed it from the Cape of Good Hope, South Africa, in the 1830s, and numbered it as h 3248, and included it in the 1864 General Catalogue as GC 2102; this became NGC 3242 in J.L.E. Dreyer's New General Catalogue of 1888. This planetary nebula consists of a small dense nebula of about 16" x 26" in diameter, surrounded by a fainter envelop measuring about 40 x 35 arc seconds. This central nebula is embedded in a much larger faint halo, measuring 1250" or about 20.8 arc minutes in diameter. The bright inner nebula is described as looking like an eye by Burnham, and the outer shell gave rise to its popular name, as it is of about the apparent size of Jupiter. This planetary nebula is most frequently called the Ghost of Jupiter, or Jupiter's Ghost, but it is also sometimes referred to as the Eye Nebula, or the CBS Eye.

M-53 Ngc – 5053
MONTHLY OBSERVER’S CHALLENGE Las Vegas Astronomical Society Compiled by: Roger Ivester, Boiling Springs, North Carolina & Fred Rayworth, Las Vegas, Nevada With special assistance from: Rob Lambert, Las Vegas, Nevada JUNE 2014 Messier 53 (M53)/NGC-5053 – Globular Cluster Pair In Coma Berenices Introduction The purpose of the observer’s challenge is to encourage the pursuit of visual observing. It is open to everyone that is interested, and if you are able to contribute notes, drawings, or photographs, we will be happy to include them in our monthly summary. Observing is not only a pleasure, but an art. With the main focus of amateur astronomy on astrophotography, many times people tend to forget how it was in the days before cameras, clock drives, and GOTO. Astronomy depended on what was seen through the eyepiece. Not only did it satisfy an innate curiosity, but it allowed the first astronomers to discover the beauty and the wonderment of the night sky. Before photography, all observations depended on what the astronomer saw in the eyepiece, and how they recorded their observations. This was done through notes and drawings and that is the tradition we are stressing in the observers challenge. By combining our visual observations with our drawings, and sometimes, astrophotography (from those with the equipment and talent to do so), we get a unique understanding of what it is like to look through an eyepiece, and to see what is really there. The hope is that you will read through these notes and become inspired to take more time at the eyepiece studying each object, and looking for those subtle details that you might never have noticed before. -

Rules & Requirements for an SBAS Observing Certificate 1. You Must
Rules & Requirements for an SBAS Observing Certificate 1. You must be a member of the SBAS in good standing to receive a certificate. 2. No Go To or Push To aided attempts will be accepted. Reading charts and star hopping are essential skills in our hobby. (You may use these methods to confirm your findings.) 3. Honor system is in full effect. These lists benefit your knowledge of the sky. Cheating only cheats yourself and the SBAS membership. Observations will be verified against digital planetarium charts. You may be required to answer questions about the objects you observed to verify your work. You may also be asked to show one of these objects at a star party. Once a list is completed, it is assumed you are familiar with every object on that list to the point where you can find it again and describe it to another person. 4. Upon completion of a list, submit the original paper version in person to Coy Wagoner at an SBAS meeting, public star party, or informal observing at the Worley. No digital submissions will be accepted at this time. 5. No observations may overlap. If one object is on two lists, your observations must be done on separate dates/times for credit. Copies of your observing logs will be saved and later compared to additional lists to make sure nothing overlaps. No observations prior to January 1, 2015 will be accepted for credit. 6. Observations should be done on your own. If you observe an object in someone else’s telescope or binoculars, the observation does not count unless you did the work to find it. -

Culmination of a Constellation
Culmination of a Constellation Over any night, stars and constellations in the sky will appear to move from east to west due to the Earth’s rotation on its axis. A constellation will culminate (reach its highest point in the sky for your location) when it centres on the meridian - an imaginary line that runs across the sky from north to south and also passes through the zenith (the point high in the sky directly above your head). For example: When to Observe Constellations The taBle shows the approximate time (AEST) constellations will culminate around the middle (15th day) of each month. Constellations will culminate 2 hours earlier for each successive month. Note: add an hour to the given time when daylight saving time is in effect. The time “12” is midnight. Sunrise/sunset times are rounded off to the nearest half an hour.

La Constelacion De Tauro
LA CONSTELACION DE TAURO Es una de las constelaciones más interesantes desde el punto de vista observacional entre las que podemos ver desde el hemisferio norte. En la zona de la bóveda celeste donde identificamos la constelación de Tauro encontramos estrellas dobles y dos bellísimos cúmulos abiertos, asi como la famosa Nebulosa del Cangrejo, objeto Messier M1. 1. Las constelaciones: una aparente imágen estelar: Desde nuestra perspectiva visual como habitantes de un pequeño planeta orbitando alrededor de una estrella en una cierta galaxia espiral, observamos, en todas las direcciones de la bóveda celeste, agrupaciones aparentes de estrellas que llamamos constelaciones. Decimos que son agrupaciones aparentes porque, realmente, no tienen que estar - de hecho no lo están en general - agrupadas físicamente. Es esta la misma situación que se nos plantea en nuestra vida cotidiana cuando observamos a lo lejos dos objetos que aparentan estar juntos, y, ante la duda de si lo están o no, nosotros nos movemos lateralmente a una distancia suficiente para observarlos desde una perspectiva lateral. Es en ese momento cuando, vistos desde otro ángulo, comprobamos si están entre sí próximos o no. Este movimiento lateral es muy sencillo de realizar en nuestros avatares de la vida cotidiana, pero es evidente que, a escala astronómica, es imposible con la tecnología existente en nuestra civilización. Es imposible para nosotros salir de la Vía Láctea, nuestra galaxia espiral, para poder observar “lateralmente” una cierta estrella doble, por ejemplo, de la que sospechamos que no es una doble física, interactuando gravitacionalmente, sino que es una doble de perspectiva. Existen métodos radiométricos, espectrométricos, etc.., que nos permiten calcular la distancia de la estrellas que observamos a simple vista, y sabemos que en general, la distancia a nosotros de astros de una misma constelación varía grandemente.
