How To Buy A Telescope In 2009

Kozsun Huseyin asked:


astronomy is both interesting topics. Science and astronomy doesn’t have to remain with the scientists of the world with lab coats, in fact you could wear a T-shirt and jeans and have a blast with backyard astronomy. Make discoveries at home and enjoy. I will tell you how! Astronomy is an amazing topic. NASA spends billions to gain more insight into astronomy. Though spending billions on a home space program is not the most feasible thing to do for most people, the truth is that you still can make some amazing discoveries, and though most of your discoveries will be limited to what has already been found, there is still room for making discoveries. Remember this is all possible from your backyard and with the right telescope. The question comes to mind though, how to buy a telescope. It is the aim of this article to get you started in the right way. Telescopes come in many shapes and forms; however the main 2 types you will run into are the reflector telescopes and the refractor telescopes. Both have there benefits, however the refractors (the type which is like binoculars, i.e. you look from the back) are great for beginners because of ease of use and low maintenance, however, they can become very expensive with larger versions. The reflectors work with a mirror and look slightly larger; however, they have the benefit that they can allow you to get some large and amazing sizes which show so much more clarity for much less when compared with refractors. Understanding how these scientific instruments fundamentally operate will allow you to answer how to buy a telescope and get a good deal in the process. The whole process is about light. Our pupil is the amount of light that we can physically get. To get a bigger image we need a bigger eye! The telescope does this and the bigger the telescope, more light gathering abilities it has. For example in reflectors the size of the mirror in effect determines how big the picture will be. Though realize that even with the biggest of telescopes, the image will still be small in comparison. So an 8” mirror will not show an 8” Moon! When asking how to buy a telescope, we want to get the best. Telescopes come in many different price ranges. My strongest suggestion is to look for a telescope above the $100 mark. Anything below this figure will likely be a flimsy toy rather than a real telescope. They can range in price from under hundred dollars to several thousand dollars. As a good version, going for a $200 to around $500 is a great way to get a good telescope that is more of an investment than an expense. This will give you something that will likely last for as much as a decade or more, if it looked after. The next question in how to buy a telescope is to actually buy a telescope. This can be accomplished through several methods such as telescope stores or direct mail, such as in advertisements in magazines dedicated to astronomy. The best solution I have found is to go online. Going online, you can expect to find a wider range of options, and the other 2 benefits is that you get the best prices in most cases, and get it delivered to the comfort of your home!

Binocular Chest Harness

Binocular Harness asked:


The word, ‘chest’ in binocular chest harness sounds kind of weird. I mean, how do you hook your optics up to your chest?? It’s kind of crazy. But what the title, ‘binocular chest harness’ leaves out is that it also uses your back and shoulders to strap your optics in. Did you notice I left out the neck? Awesome, right? You have no idea.

Anyone who uses binos without binocular chest harness systems knows exactly what I’m talking about. Almost every optics strap is a single band that rests right on the lower part of your neck. Well, that only works for a few minutes before your muscles start to tense. It’s crazy, really. Who would have thought that those itty bitty little optics could feel like they weight 50 lbs? With a binocular chest harness, they don’t.

The binocular chest harness can double for a camera strapping system, too. I know, right. It’s awesome. Cameras have been a big problem up until I discovered the binocular chest harness. I mean, what are you supposed to do with them? You can’t walk around the whole day with the use of just one hand… (I apologize to any of you who had an accident and are only left with one hand.) But honestly, we have two hands for a reason, and that reason is not to carry around binos or cameras all day.

Not only do I not have to carry either of these items in my hand or on my neck, but I can also rest assured with the binocular chest harness that they will be safely protected. Those single band straps allowed them to swing all over the place before. So not only did my neck hurt, I constantly was banging them around. I mean, these succors aren’t cheap, am I right? I have to be careful with mine and that’s why I only use a binocular chest harness anymore.
