Bradford and I had out the telescope. We spread our two legs as we spread its three, Pointed our thoughts the way we pointed it, And standing at our leisure till the day broke, Said some of the best things we ever said. That telescope was christened the Star-Splitter —Robert Frost Star-Splitter (Credit—Joe Orman).

The Night Sky Companion is full of information about astronomy. Think of how many times you have walked outside, looked at the stars and wondered what new things you could explore. Maybe you are a beginner and you want to learn the basics of stargazing, or perhaps you’re a seasoned sky veteran. Either way, I bet you will see and learn something new each night. I have used Tammy Plotner’s previous books to help plan my outreach programs. Not only do they tell you what you can see in the night sky, just as this book does, but they also explain some of the history and science which has brought us to this point. You will quickly realize astronomy is what you make it. It can be extremely challenging or very relaxing: it’s up to you to decide. With this book, you can use telescope or binoculars of any size—or just kick back under the Milky Way and enjoy the view. It will be your “companion” to help you discover our galaxy. Picture yourself enjoying a warm August night watching the Perseid meteor shower, or seeing the Harvest Moon rise. While the spring holds the promise of bright planets and distant galaxies, there is something to be said about those long, cold winter evenings too! You can spend hours observing and still get to bed before midnight. With each changing season, with every constellation wheeling overhead, Tammy will show you the best of the night sky. The wealth of information here about the Moon will amaze you. Wait until you point a telescope its way and find a specific crater. Suddenly, the lunar terrain takes on a new look. It has a stark beauty which will keep you coming back. ix Ohio Aurora in May (Credit—Terry Mann). Foreword xi Both beginning and advanced amateur astronomers will enjoy this book. There is something for every level of knowledge and any type of astronomical interest—for each night of the coming year. The vivid descriptions and beautiful images presented here will help you see objects more clearly, and Tammy’s insights into what you’re looking at will guide you through your observations. Her intimate knowledge of the sky shines throughout her book. Use this book as a learning tool for yourself and your family. It is a great primer for science students. Don’t let another night fade away, let’s go out and see what it has to offer! Terry L. Mann President, Astronomical League Acknowledgments When one has weighed the Sun in balance, and measured the steps of the Moon, and mapped out the seven heavens, there still remains oneself. Who can calculate the orbit of his own soul? … We are all on our backs in the gutter, only some of us are looking at the stars. —Oscar Wilde Throughout the years, it has been my great pleasure and privilege to know many professional and amateur astronomers. I have been inspired by countless books, magazines, and programs, and have spent years of starry nights at the eyepiece in study. It is a combination of all of these things that makes this book what it is. And makes me who I am. For all of you out there? I thank you. Your support and kind words have made a dream come true. Now let’s thank the people who made it come about... Ricardo Borba Ricardo Borba is an amateur astronomer living in Ottawa, Ontario, and a member of the Royal Astronomical Society of Canada. Between observing sessions he is an application software engineer at Natural Convergence and his photographic skills are becoming highly acclaimed as they are featured in various publications. www.borba.com xiii xiv Acknowledgments NGC 1579—(Credit—R. Jay GaBany). Alan Chu As a resident of Hong Kong, Alan might joke that the Moon is all he has to observe due to light pollution, but Alan’s work is no laughing matter. He has produced one of the finest amateur Photographic Atlases of the Moon available and it is a great honor to include his fine photography in these pages. www.alanchuhk.com John Chumack

The School established a Recognition Committee following the Royal Commission’s public hearings, which met three times in 2016. The School implemented the major recommendation of the Recognition Committee by appointing a Survivor Liaison Coordinator, Renee Handsaker, to provide outreach and support to survivors of child sexual abuse at the School. Ms Handsaker has performed a vital role assisting survivors in a confidential and independent way. Her role is complimentary to, but separate of, the independent counsellor provided by the School to offer counselling and advice. The Royal Commission released its final report from the School’s case study in February 2017.

  • Three Decades of Small-Telescope Science
    Three Decades of Small-Telescope Science A Report on the 2011 Society for Astronomical Sciences 30th Annual Sym- posium on Telescope Science Robert K. Buchheim For three decades, the Society for Astronomical Sciences has supported small telescope sci- ence, encouraged amateur research, and facilitated pro-am collaboration. On May 24-26, more than one hundred participants in the 30th anniversary SAS Symposium heard presentations cov- ering a wide range of astronomical topics, reaching from the laboratory to the distant cosmos. From Planets to Galaxies Sky & Telescope Editor-in-Chief Bob Naeye opened the technical session with a review of the amateur contributions to exoplanet discovery and research through monitoring of transits and micro-lensing events. R. Jay GaBany described his participation as an astro-imager in the search for evidence of galactic mergers. His exquisite deep images taken with his 24-inch telescope displayed the di- verse patterns of star streams that can be left behind when a dwarf galaxy is disrupted and ab- sorbed by a larger galaxy. He also noted that not all faint structures are evidence of galactic mergers: the faint ”loop” structure near M-81 is actually foreground “galactic cirrus” in our own Milky Way masquerading as a faux tidal loop. Education and Outreach Several papers related to education and outreach were presented. Debra Ceravolo applied her expertise in the generation and perception of colors, to describe a new method of merging narrow-band (e.g. Hα) and broad-band (e.g. RGB) images into a natural-color image that displays enhanced detail without glaring false colors.

  • To Photographing the Planets, Stars, Nebulae, & Galaxies
    Astrophotography Primer Your FREE Guide to photographing the planets, stars, nebulae, & galaxies. eeBook.inddBook.indd 1 33/30/11/30/11 33:01:01 PPMM Astrophotography Primer Akira Fujii Everyone loves to look at pictures of the universe beyond our planet — Astronomy Picture of the Day (apod.nasa.gov) is one of the most popular websites ever. And many people have probably wondered what it would take to capture photos like that with their own cameras. The good news is that astrophotography can be incredibly easy and inexpensive. Even point-and- shoot cameras and cell phones can capture breathtaking skyscapes, as long as you pick appropriate subjects. On the other hand, astrophotography can also be incredibly demanding. Close-ups of tiny, faint nebulae, and galaxies require expensive equipment and lots of time, patience, and skill. Between those extremes, there’s a huge amount that you can do with a digital SLR or a simple webcam. The key to astrophotography is to have realistic expectations, and to pick subjects that are appropriate to your equipment — and vice versa. To help you do that, we’ve collected four articles from the 2010 issue of SkyWatch, Sky & Telescope’s annual magazine. Every issue of SkyWatch includes a how-to guide to astrophotography and visual observing as well as a summary of the year’s best astronomical events. You can order the latest issue at SkyandTelescope.com/skywatch. In the last analysis, astrophotography is an art form. It requires the same skills as regular photography: visualization, planning, framing, experimentation, and a bit of luck.
