The bright face of our planet’s Moon has been inspiring astronomers for centuries. Since the Moon is much closer to Earth than any other object in the night sky, views of its illuminated surface are amazingly detailed when observed through binoculars or a telescope. Intriguing craters, craggy mountains, and vast “seas” of ancient lava flows make for wonderful targets for backyard astronomers. With the affordable Orion Moon Map 260, you can easily identify, locate and learn about the many interesting features of Earth’s only natural satellite.

The Moon Map identifies over 260 of the most popular lunar surface features including craters, mountain ranges, valleys, rilles, “seas” and more. Each feature is cross-referenced in the MoonMap’s tables with its official name, size and a brief description. In addition to lunar landscape features, all successful spacecraft landing sites from US Apollo, Surveyor and Ranger Probe missions as well as Soviet Luna Probe missions are also clearly identified on the map.

We’ve designed the Orion MoonMap 260 with versatility in mind. Both a correct-image and reversed, or “mirror image” view of the Moon are included on the map, so it can be used when observing the Moon with unaided eyes, binoculars; or any refractor, reflector, or Cassegrain telescope. The map is conveniently laminated for use in almost any weather.

Using the Moon Map 260 is easy. Simply find the reference number of the lunar feature you wish to identify on the map, and then look up its name using the map’s numerical index. Conversely, if you wish to locate a specific named feature with your telescope or binoculars, use the map’s numerical index to find the lunar feature’s reference number, then locate the number and feature on the map. For ease of use, the reference numbers are roughly ordered from north to south (top to bottom).

Born and raised in remote Broken Hill, Trevor Barry left school after year ten to work in the mines. Years later, a single glimpse of Saturn through a colleague's telescope knocked Trevor's world completely off its axis, turning his whole life upside down.

With his newfound passion and armed with decades of outback know-how, Trevor set about building an observatory in his backyard using bits and pieces from his shed, a second-hand washing machine motor, rainwater tank parts and an old catamaran wire. It took some canny negotiations with his wife, Cheryl, 'the Gorgeous and Adorable', whose prized garden took a battering - especially when he decided to add a second storey - but before long Trevor was not just gazing at the stars but capturing extraordinary images of the planets.

Over the years, Trevor's love affair with Saturn, 'the ringed jewel of the solar system', only grew more passionate, and in his early fifties he did a degree in astronomy, topping his class.

When he recorded a massive storm on Saturn from his backyard observatory, he alerted NASA. The world's greatest space agency took note and invited Trevor to contribute to its interplanetary research - leading to opportunities far beyond Broken Hill and even Trevor's wildest dreams.

Today, when he's not tending the greens at his local bowls club, Trevor can usually be found in his backyard, collecting data for international research projects. His work is held in high regard by professional astronomers, and his observations are published in peer-reviewed scientific journals around the world.

About Trevor

Trevor Barry has called Broken Hill home his whole life. At 17, he started work in the local mines and built a good life there, married to his high school sweetheart, Cheryl, the Gorgeous and Adorable. But then Trevor fell in love again - not with Cheryl, but with a planet: Saturn. Just one look through a telescope changed his life forever. First he built his own telescope, and then an observatory - until finally, at 51, Trevor decided to gaze at the stars full time and enrolled at university to study astronomy. He now collects data vital to NASA research and is renowned for his extraordinary photographs of the planets.
