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 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. -

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. They are dense systems, which uses up all its fuel, it collapses. The collapse contain thousands or millions of stars.

Astronomy 142 — Project Manual Spring 2021
Astronomy 142 | Project Manual Spring 2021 1 RR Lyrae stars and the distance to globular cluster M3 1.1 Introduction In the following, we repeat a classic experiment: detect the periodically-varying stars in a globular cluster and thereby measure its distance, by considering the stars to be standard candles. Specifi- cally, we will measure the time-average luminosity of the nearby star RR Lyrae and the time-average flux of stars in M3 that vary with the same period as RR Lyr, combining these measurements to determine M3's distance. This observing project will involve frequent remote observation sessions with the tele- scope over the course of 1{2 weeks, hopefully including a few nights in a row. Everyone who opts for this project will share their data and receive everyone else's in return. Each student will perform his or her own analysis and write an independent report on the results. Stars in the instability strip of the HR diagram have been fundamental in the determination of the distance scale of the Universe. These stars radially pulsate, often in their fundamental acoustic mode. As we have seen in class, their pulsation periods Π vary inversely with the mass density ρ of the star: Z R dr r 6π Π = 4 =∼ (uniform density star) (1) 0 vs γGρ Lower average density leads not only to longer periods, but also to larger luminosities L, in part because lower-density stars are much larger than higher-density stars of the same mass. Thus, a given type of pulsating star exhibits a strict relation, often linear, between Π and L. -

SSAS Marmesmad Doc
The South Shore Astronomical Society and Unistellar Optics present An Initiative to Engage in Astronomical Observing Welcome to the month of March, a time of the year when astronomy enthusiasts can view every object in Charles Messier’s venerable catalog of ‘non-comets’ in the course of just one overnight, should they choose to do so. But seeing every Messier object in one night, also known as a Messier Marathon, is a daunting prospect indeed. The observer needs to be blessed with not only dark enough skies and low enough horizons to see the very first and very last objects on the list, but he also has to get lucky with the weather and have clear skies for a nearly twelve hour stretch throughout the night. The first two requirements can be met by carefully choosing your observing site. The third, unfortunately, cannot. For these reasons and perhaps others, most observers tend to shy away from Messier Marathon participation, especially when the group you’re affiliated with insists on sticking to a purist’s approach – the one where only star hopping to every object and only visual sighting through the eyepiece is considered the right way to do it. While there is something to be said for completing the challenge in that manner, it also has a tendency to push many would-be observers to the sidelines. So what if the rules were changed? And what if a variety of approaches to observing Messier’s during the month of March were considered not only acceptable, but were encouraged? Enter Unistellar Optics, a French company that markets a unique telescope, the Unistellar eVscope. -

Amateur Astronomy in the Winter Sky
Amateur Astronomy in the Winter Sky Dale Hachtel Popular Astronomy Club Jan 4, 2020 The Andromeda Galaxy – Anthony Watt Orion Nebula – Anthony Watt January can be a difficult month for amateur astronomers, with cloudy and snowy skies and cold nights. Most of the planets we enjoyed viewing in the evening during much of 2019 are viewable only briefly in the early morning now, but there are still many interesting objects in the winter sky. Winter is therefore a good time to learn about what’s up in the sky besides the familiar constellations, planets, and well-known stars. The Astronomical League (AL) is a non-profit organization that promotes the science of astronomy. The organization does this by fostering astronomical education and providing incentives for astronomical observation and research. It is composed of 240 local amateur astronomical societies. The North Central Region of the Astronomical League (NCRAL) includes the Quad-Cities area, Illinois, and states north and northwest of the Quad-Cities and contains 36 of the amateur organizations. At the NCRAL convention in May 2019, hosted by the Popular Astronomy Club (PAC) in Moline, an interesting and educational amateur program was introduced for the NCRAL area. This NCRAL Seasonal Messier Observing Program provides a framework for amateur astronomers to learn about and observe some of the more interesting objects in the sky. First, a little background about Messier. Charles Messier was a French astronomer who studied comets. Between 1774 and 1781, he compiled a catalog of objects in the sky that could be mistaken for comets. His catalog, with a few 20th century additions, still provides a list of 110 interesting objects for amateur astronomers to find and observe. -
