Telescopes

Ok, now that I’ve got your attention, let’s be honest here, there really is something umm unique about our South American female friends. Brazil has had some rather interesting ‘exports’ of interest. Many of these exports have benefitted us men immensely. I introduce to you what I call ‘The Brazilian Trifecta’- The Brazilian Bikini, the Brazilian Wax and the Brazilian Butt.

I just got back from the beaches of Rio and quite honestly it’s hard not to notice how the women value a very distinct kind of sensuality there. Not the slutty bleached blond bimbo variety that we have come to know and love here in the States. But, rather the, ‘I own this sh*t’, and I’m going to torture you with it kind. Let’s explore the first of the above three trifecta. The Brazillian Bikini. Feared by many women around the world and endorsed by all males, who, well…breathe.

The Brazilian Bikini: Here’s the rub on this one (that was an unintentional pun) Brazilians wouldn’t dream of going topless, conversely, women would consider it in the States (and often do in places like South Beach). Brazilians wouldn’t think of wearing a full bikini bottom but it’s our ladies bikini of choice in the States (Brazilians find it just too ‘granny panties’ for their taste). Many in the States see the ‘Brazilian cut’ and scream ’slutty thong’. So who’s right? I think the short answer is- they just work what they got! And what they got- is a crazy Brazilian butt! Which leads me to number two in my Trifecta.

The Brazilian But: What they heck is this thing anyway? You can spot it from space without using the hubble Telescope. I think Justin Timberlike said it best “she looks like a model except she has a little more a**”. It’s like two perfect well shaped legs with this perfect thing on top. Hard to describe but you know it when you see it. Women know it all to well. In fact women are so aware of it that butt implants are now in the top 5 of the most performed female plastic surgeries. Google “butt implants”, I dare you, your computer will blow up. This leads me to the third and final area in my trifecta- The Brazillian Wax.

Brazilian Wax- Without the Brazilian wax, the Brazilian bikini would be impossible! Every now and again the god’s shine down on men for no good reason at all and throw us a bone. The Brazilian wax is just that bone. Since necessity is the mother of invention, it makes perfect sense that when a girl wears a bikini that almost disappears, unless she wants to look like Chewbacca she needs to take care of her business down there. Men, listen closely, their down side is our upside! The possibilities here are limitless! Trust me here- I got your back.

I say long live Brazil and thank Christ the Redeemer for their little contribution to my already amazing life.

The science of astronomy goes back as far as man does. Today it is an applied science based on carefully gathering and analyzing data, but there was a time it was little more than charlatan magic. Astronomy is something too many people ignore, but those who keep their eyes on current happenings in astronomy find a wealth of interesting information.

Australians were urged to look up and maybe duck in November when a 1400 LB Ammonia tank threatened to fall on them. It was tossed into space when it was deemed too dangerous to carry down to Earth on a shuttle. By good luck most of the pieces, no larger than fifteen pounds, were expected to fall harmlessly into the ocean. Although possible Ammonia residue would likely wash a lot of windows, this isn’t recommended as a mass cleaning method. Paul Hogan, the famous actor who played Crocodile Dundee, was unharmed. Unfortunately, according to the Daily Mail in the UK, Steve Irwin, the Crocodile Hunter, remained deceased after this incident.

New line China, September 2008, a 3rd manned space mission launches. It will include the first space walk for Chinese astronauts. Unfortunately for China it was revealed that “live video” of the successful launch and flight into orbit had actually been released before the craft left the ground. It wasn’t a hoax. China simply thought the event so important that they carefully staged a video log as public relations.

Also from China, a huge Telescope has been commissioned for construction near Beijing, site of the 2008 summer Olympics. Revolutionary is the way this telescope tracks the sky – with two moving mirrors. The resulting look is something of a curiosity. This one is shaped like a leaning arch. That’s the Chinese, making art from science.

In Kazakhstan of all places a new satellite was launched in early November of 2008. Satellite Astra-1M will be used for telecommunications. The launch vehicle was called Proton-M.

Astronomy hobbyists will love Worldwide Telescope which is of Microsoft and  works in windows to call images from all over the world, delivered to the user. It’s like an observatory on a desktop. The only downfall is that no new discoveries can be made, because it’s all pre-compiled astrological data and images.

Telescope is an exciting physics equipment. Buying a telescope is a daunting task for a newcomer. It all depends on your astronomy goals and careers. There is no perfect one which suits all observers in all conditions. You have to look for the features you want in your telescope and select the best one’s according to your requirement.

Selecting the proper type

• The refractor type telescopes best suit for watching moon and major planets. Refractor telescopes are long & thin, and known for their sharp, detailed and contrasty images. They collect light through multi-element lenses. If you are just a starter then a small, quality achromatic refractor of 60 to 90 mm aperture would be a good one. The best thing about a refractor telescope is that they are inexpensive, portable and almost maintenance free. A refractor Telescope is also useful when you will be mostly observing from city or the surrounding areas where the night skies are lightly polluted.
• Reflector telescopes are also known as Newtonian telescopes. They are good for planetary as well as deep-sky viewing. However Newtonian telescopes are more fragile and need more maintenance than others. These telescopes collect light with a curved, concave mirror and with the help of their large apertures, they show fine, highly-resolved images. The reflector scopes are not suitable for terrestrial viewing because they produce an upside-down image.
• Catadioptrics use both lenses and mirrors to collect and focus the incoming light. They are also called compound telescopes. Catadioptrics scopes are considered the most versatile telescopes and gives great all-around performance. They use a large aperture in very compact tubes. They show magnificent images of the moon, planets and faint deep-sky objects, when viewed in dark skies away from urban areas. These scopes are best suited for astrophotography. Compared to other two, these scopes have a wide range of accessories available. They can be entirely computer controlled.

Factors affecting the performance of a telescope

• • Aperture: Telescopes collect light from distant objects and focus it to produce images. The light collecting capacity of a telescope is the most important feature. It is the aperture of scope (diameter of mirror or lens) that is responsible for gathering light. Larger the aperture, the more light gathered, the more you’ll see.
  • Telescope Mounts: There are three basic mounts for telescopes altazimuth, Dobsonian, or equatorial. Altazimuth is the simplest type of mount, providing up-down, left-right motions. It is mainly recommended for terrestrial viewing and casual stargazing. The Dobsonian mount was basically designed for easy maneuvering of large reflectors of more than six inches. It is a boxy altaz-type mount sitting close to the ground. Equatorial mounts are designed for the purpose of astronomical viewing. These mounts are more expensive and complicated than the altazimuth mounts. With the help of these type of mounts users can track or follow the motion of celestial objects through the sky with a single manual hand control.
  • Magnification: Magnification should never top the priority for buying a telescope. The quality if image degrades with magnification. Practically 300X is maximum magnification for good quality images. Telescope’s magnification is also known as its power and it is adjusted by changing eyepieces. Ideally there should have been three eyepieces for the magnification of a scope: one low, one medium and one high. Lower powers of 30 – 50X are recommended for observing galaxies, star clusters and nebulae as they are spread over a wide area of sky. For observing the rings of Saturn, Jupiter, studying craters and valleys of the Moon’s surface medium power of 80 – 100X are advised. Higher powers of 150 – 200X allow the astronomers to observe mountain peaks and fine lunar detail, the surface features of Mars.

I am a laboratory analyst by profession working in this industry from last 10 years. I have been running a site http://www.laboratoryequipmentworld.com on laboratory equipments. It includes the largest range of laboratory apparatus and other updated info on market, trade fairs, news, etc.
