Celestial navigation is a way to find your latitude and longitude on earth using a sextant to measure the angular heights of celestial bodies above the horizon. It has been used by mariners at sea and explorers on land for three hundred years, and it is still used today as a dependable backup to modern electronic navigation. Routine celestial navigation relies upon accurate time (Universal Time) to find the longitude of a position (latitude does not require time). Advanced celestial navigators can find longitude without knowing the time using a technique called Lunar Distance. In this technique, the sextant is used to measure the angular (diagonal) distance between the moon and another celestial body. Since this distance slowly changes as the moon moves eastward though the stars, it can be used to find the time of day that is needed to complete the longitude determination. The process of finding longitude from lunar distance, however, requires special tables that have not been published in the Nautical Almanac or other sources since the early 1900s. Although software solutions have been available, most advanced celestial navigators are very grateful to navigation historian Bruce Stark for creating these printed tables dedicated to this task. They have been used and tested by mariners for more than 15 years and are praised by experts for their ingenuity and ease of use in solving this complex navigation exercise-which all agree is the hallmark of an expert celestial navigator. With The Stark Tables in your nav station, you no longer have to fear losing power to your electronic navigation aids, nor are you dependent on accurate time from any official broadcast. Besides their practical use in back up navigation, historians have used these tables for years to interpret the logbooks of Lewis and Clark, David Thompson, James Cook, Matthew Flinders, George Vancouver, Nathaniel Bowditch, and other notable explorers and sea captains. "It is remarkable in this day when the very survival of celestial navigation seems in question, that an individual should suddenly appear on the scene and present to the world such a brilliant piece of work. Stark has rendered a great service to the celestial navigation community." - Robert Eno, The Navigator's Newsletter "Captain Cook would have relished using these tables, had they been available to him then." - George Huxtable, FRIN

Great toy for a GSD
Color: Blue Gray, Size: Extra Large Size 5 (9")
My GSD loves to grab the flaps and shake her head with the ball bouncing of the side of her head. This is her favorite toy. I thought she would puncture it but it has held up great since she likes to grab the flaps rather than biting the ball.

Great toy to play fetch with the dogs.
Color: Black/White, Size: Large
These balls are a great dog toy to play fetch with your dogs. This not the first ball I have gotten for the dogs. Just the right size and weight for medium sized dogs. I have less concerns about them possibly choking on these soccer balls versus tennis balls. So I can leave them out for them to play with. The are easy to inflate using the included pump. My only concern is the durability of the straps as my dogs have almost torn off one the straps of the previous ball I purchased.

Westie LOVES this toy
Color: U.S.A, Size: Medium
My pup (Westie) adores this toy. This is actually our second one. The ball itself is resistant but the straps will be obliterated. Would definitely recommend! Totally worth the price!

Not durable
Color: Black/White, Size: Large
If you have a dog who likes to pop things then this toy isn't it. Within 5 min she had this ball popped. It was made to sound like it was durable for this type of thing but it definitely is not so just be aware. Now if you have a dog who doesn't pop things easy then this would be a good toy
