Choosing The Right TelescopeDuane Brown Ever since Galileo, people have been pointing telescopes to the heavens and expanding their view of this world by looking outside of it into other worlds. It can be a fascinating and rewarding endevour. You can even meet some very good friends this way as there are usually local star-gazing clubs within reach of almost anywhere in the country that offer plenty of companionship when using your telescope. But how do you choose from the wide array of telescopes that are being sold today Well, first of all you need to understand just a couple of basic points about telescopes. One is that magnification is not really the most important characteristic of a telescope. That may seem very strange, but the truth is that the most significant capability of a telescope is its ability to gather light. After all, what good is a large image that you can barely see The light gathering capability of a telescope is usually in direct relation to the size of its aperture or its light gathering lens or mirror. Now, you are probably thinking that you just need to get a telescope with the largest aperture possible then, but that is not the case. Somewhere along the line there will be a tradeoff between the size of the aperture and portability. So if you want to transport your telescope at all, you will want to make sure that it is not too heavy and bulky to be mobile. Remember that you will also most likely have to set up and adjust your telescope in the dark if your transport it, so having one that is very large can be a daunting task when you cant see what you are doing very well. On the magnification factor, you can adjust the magnification of almost any telescope through the use of different eyepieces, so that is not a really important consideration when buying. Its also important to know that there are three different kinds of telescopes, the reflector, refractor and catadioptric. The refractor is the kind of telescope that most people think of when they think of telescopes. It essentially has a large lens on the end of a barrel that focuses an image on an eyepiece at the back of the barrel. Its actually a very simple design, but it can also be more costly and bulky than the other styles of telescopes available. Its good for viewing the night sky and long range here on earth, but again, it gets very expensive to produce when you want to see deep space objects. The next kind of telescope is the reflector, and it uses mirrors to gather the light and focus it on a small eyepiece that is usually located on the side of the barrel. Mirrors are much less expensive to produce than the lenses used in refractors, so the reflector telescope is usually much less expensive as well. It is not suitable for terrestrial viewing here on earth though and it does lose a little light due to the use opf mirrors in its design. The final style of telescope is the catadiaoptric which is really a blend of both refractors and reflectors, essentially taking the best of both designs with few of the drawbacks. It is a good all around selection for telescope usage as it is a good choice for both terrestrial and astronomical viewing. They may not be what you expect a telescope to look like but their design is very modern and durable. Choosing any of these types and styles of telescopes will work depending on what you plan to use your telescope to do, and your budget. The important choice is to embark on a discovery of parts of the universe that you have never seen before.

Let There Be Light, Part 1 – The Camping Lantern The only thing worse than setting up a tent in the rain is setting up a tent in the rain in the dark.

Keys to Responsible Recreation in the BackCountry Having a good time is pretty high on everyone’s to do list, especially when surrounded by awesome views and super-awesome friends. We hike, bike, climb, camp, raft, fish, hunt, four-wheel, sleep and eat – among other things – in the backcountry. If not done properly, that’s a lot of wear and tear on our natural resources. Responsible recreation ensures future outdoor enthusiasts the opportunity to enjoy the outdoors as you have. Without a recreation code of ethics, our backcountry would become a thing of the past. Here are some universally agreed upon keys for having a good time – the right way.

Why I Would Rather Be A Slugger Than A Pitcher During the last NLCS, I asked Brandon Backe of the Astros what the hardest thing was for him in making the conversion from outfielder to pitcher in the minors. He said it was "not playing every day." That is why I would rather be a slugger, to answer your question. Id want my mind and body to be in every inning of every game. I wouldnt want to be one elbow injury away from a possible end of my career or a lost year. I listened to Nolan Ryan talk at the last All-Star FanFest in Houston about how he would have to "rebuild" his body from one start to the next, an incredibly arduous process that the great pitchers know and few fans realize. Ryan would be on the bike immediately after each start, and he said his physical strength would go down to about 50 percent a day or two after each start, and then his mission was to get it back up to 100 percent by the next start. As the slugger you mentioned, Id love to be in that zone of hitting in the cages every day and be able to "slow down" every pitch like Manny Ramirez and Albert Pujols do so incredibly well. 2005 - The Year of Patience 2005 has me going into my 15th year teaching golf.From day one, I thought that if I could come up with a technique that was fast and easy to learn I would be a pretty popular guy.Well, I did ... and I am.So what is fast and easyDoes it mean that if you take one lesson with me I can get you to shoot 72Well ... if I could get you to shoot 72 in 1 lesson I would charge $10,000 per lesson and the line up to see me would be down the street.I do get lucky sometimes but for the most part it usually takes me a little longer.

The Long Backswing Is your golf swing too longThe majority of inexperienced players I see have too long of a golf swing.So why would so many people have such long swingsIt all boils down to Human Nature.Human Nature says that the longer you swing the farther you will hit the ball.If this were true, why is it that I can hit a ball 300 yards with a 3/4 swing but I can’t hit it 400 yards with a long swing A Bet You ALWAYS Win - How Sports Betting Arbitrage Works Betting arbitrage is a method of creating a bet that has a zero risk - in other words, you always win! The concept of arbitrage comes from the financial world, and describes the activities of traders who find two different places offering the same trade, but at different prices. They then exploit this difference by selling in one location and buying in the other. Whatever happens to price, they make a profit on the difference between the original 2 prices. The same thing applies to betting arbitrage, typically on sporting events. The Reason Why Clone Golf Clubs Are Worth It! When it comes to choosing a new set up of golf clubs, you are obviously going to want the best, but more importantly you are going to want them at a low cost. This is why manufacturers have decided on the idea of clone golf clubs. They not only play the same but are almost made to look the same as well. Customers are going to see that the prices are lower and that they are just as good as the “very, very best” which is why retailers capitalize on this. Hell-Roaring Creek The first Summer that I lived in Colorado provided me with an opportunity to do some field work in the western Rocky Mountains.To reach my first campsite, I followed a rutted dirt road along the bank of Hell Roaring Creek, and found a rocky path that led to an abandoned mine.A cold, mountain stream gurgled and murmured within its narrow banks, at the bottom of a narrow defile carved by furious erosion to expose towering, jagged cliffs of maroon sandstone on one side, and a more gently sloping mass of granite on the other.By early afternoon, the maroon hills were softened by shadow, too steep to allow even the high Colorado sun to fully illuminate the bottom of the miniature gorge.I unfolded my double-burner Coleman stove, and placed it carefully on the hood.As the twin burners hissed bright blue heat, searing mixed vegetables on one side and Dinty Moore on the other, I watched swallows dart after insects against the backdrop of the waning Rocky Mountain sunset.I basked, self satisfied, in the sounds of the gurgling creek, the ever softening sunlight, lengthening shadows, and lilting, cool breeze.As dusk encroached, I settled in by flashlight with a Stephen King novel.I read, mesmerized as rain pattered on the roof and lightning flashed, momentarily revealing the churning mass of foliage around me and briefly illuminating the high cliffs, now turned blood-black. Gamers in the Game Sometimes at night, while I sleep, I dream that I am the point guard on Michael Jordan’s Chicago Bulls. Other nights, I bat cleanup for the Chicago White Sox. If that isn’t busy enough, I still often find time to quarterback Jimmy Johnson’s Dallas Cowboys.
