The Moon has seen a resurgence of interest in the last few years, both in space exploration and among amateur astronomers. Of course, it’s always been of interest to military people, hunters, fishermen and gardeners as well as to those where the Moon plays a large part in their religion.

Telescope sales have exploded in the last five years as the cost of a decent instrument has fallen so low that very good ‘scopes now only cost a couple of hundred dollars. This has opened up the skies to a whole new generation of skywatchers.

As our cities grow ever larger, the amount of lighting has also increased and many city-dwellers are hard-pushed to see anything but the brightest stars in their neon-glow skies. But the Moon, being the second brightest object in the sky (after the Sun) suffers no such indignity. It serenely crosses the sky, ever visible (providing clouds allow!) regardless of the amount of light pollution.

LunarPhase Pro produces a calendar of Moon Phases (a moon phase or lunar calendar) amongst many other features. By using the integrated observation planning tools and the general lunar data presented on screen, you’ll be able to easily plan for an observing session and be productive while observing.

Want to know when the next full moon occurs or the moon phase today, when the moon will be visible tonight or when is the full moon this (or any) month? LunarPhase Pro answers these questions and includes a huge range of features, all integrated together into one low cost solution.

No other moon astronomy software package matches the range of tools included.

Described by one reviewer as the Swiss Army Knife of Moon software, LunarPhase Pro has been written with you, the observer, in mind and is very easy to master and use. Its simple, yet powerful features will provide you with the information you require to make your Moon observing sessions more fun!

Astronomy For Kids

If you’re into astronomy for kids, then the software is a great teaching tool and many teachers have bought it to educate their pupils about the Moon and its motions.

Astronomy For Beginners

If you’re a beginner in the world of astronomy and new to amateur astronomy, then there’s no better object to start your astronomical journey with than the Moon. No matter how light polluted (or not) it is where you live, the Moon can always be observed, apart from when clouds get in the way.

And there’s far more to the Moon than an orb that moves about the sky. With LunarPhase Pro, you’ll discover the phases of the moon, lunar libration and where and what features are on its surface. And the software has a telescope simulator just for those cloudy nights when they do occur!

Moon Phases

While the Moon’s phase is constantly changing, there are four well-known lunar phases: full moon, last quarter, new moon, and first quarter.

In between these four major phases, the moon goes through additional phases, changing slightly each day: gibbous waning moon, crescent waning moon, crescent waxing moon and gibbous waxing moon. These all make up the 8 phases of the moon.

Using LunarPhase Pro, you’ll be able to see these phases occurring at an accelerated rate (with the animation of the moon for a month) and you’ll see how the changing phase, combined with lunar libration changes how the moon looks from day to day.

I am in Iraq stationed north of Baghdad, and I saw your program and really liked it. I fly Apache helicopters for the U.S. Army and the phase of the moon has a lot to do with our missions at night. The Apache doesn’t need illumination from the moon for night flying because our night system is infrared imagery, but we support ground troops who use night vision goggles that do require illumination from the moon. This program will help me keep up with moon phases without checking our weather reports. – Glenn Phelps
I have now had a good explore of LunarPhase Pro and I must say it is a really nice piece of software, well worth the money. I can only give it a thorough ‘thumbs-up’. Very nice and I’m sure it is going to come in very handy with all my lunar explorations. – Mark Zambelli
I am very happy with your product. It is more than I thought it would be. I have spent hours studying the moon on my first day with Lunar Phase Pro. I have learned more tonight than I have learned the last number years of reading and sighting the moon through my telescope. And the weather hasn’t bothered a bit! Thanks, Gary, for helping me through the installation process. Your customer service is excellent. I am very happy. – Gary Cowles
Let me be the first to say…I am OVERWHELMED!!!!! The program is simply OUTSTANDING!!!– Chuck Lee
I am completely gobsmacked with what you have produced. When my LX200 arrives at the end of October I can assure you I will be making good use of the Rukl map, both the book and definitely the LunarPhase Pro version as well. A bloody good job cobber, keep up the good work.– Richard Arnold
