Refracting Telescopes–An Overview

Refractor Telescopes are probably the oldest type of telescopes.  They are also extremely common.  This is because of the simplicity of construction.  The telescope consists of a hollow tube with lenses which refract the light.  This produces the magnification of the distant object.

Refracting telescopes are also known as dioptric telescope. 

Refractors are also cheaper than other types of telescopes.  You will find them in hobby stores as well as in your neighbourhood departmental store.  These telescopes are lightweight and are easier to care for and maintain.  For the amateur astronomer, this is often the first telescope.

The downside of these telescopes is that they get very heavy for larger apertures.  Hence, at higher magnification required in professional astronomy, they are not much used.  Besides, there is the problem of secondary colour (chromatic aberration).  The lens gets too big for higher magnification which causes the lens to sag

Modern materials used in lenses have improved the quality of images.

The refracting telescope can provide good images of the moon, planets and other deep space objects. 

Since you seem to be buying into everything other thing said to you that is outside your naive little sheltered world. I thought I would throw in some more stereotypes in there for you. 

It is called taking this piss, and I was taking the piss out of you.

Since well, you actually took the piss out of someone who was scared of actually dying under the Conservative government. Which well, I think that says a lot of about you. 

Also your post considering the context of our discussion seemed like you doubted that I would have been to university. You seemed to keep bringing up the fact you were going, over and over again. Since you have actually brought it up several times at this point.  

Like it seemed to make some kind of difference to the point I am trying to make. No it doesn't, not at all. You look like a moron because you can’t even form an argument, or use correct English. You are very quickly showing that you have no idea what you are talking about. 

You are a clueless child, and is clearly acting like one!

Do you want to compare university cock sizes? Then would you like to move on to IQ’s? Or did you miss the fact I pointed out that this had no baring on the points I am trying to make? Seriously?

Oh so you need proof that I went to uni? Cos, like wot shite is dis mate? Like how da fuck did a Northerner get into uni init, mate? Like how da fuck did she afford to go, like wot mate? 

You mean you are crying like a little bitch because I am making you look like an idiot again? Baww… Cry harder!

I have a really good degree in Biological Sciences in one of the best universities in the country. One that boosted about 97% of people going into further education or full time employment after leaving at the time. How does any of this change the validity of our points? How does this have any impact on how our current democracy is not fit for purpose? Since you keep bringing up the university thing up? 

Or are you wanting to call me a pleb, but it is not quiet working so your dancing around the word?

I have already explained why you should use your best English on international sites. Plus it is funny when you cry about it when I point it out. It is even funnier about your crying and complaining about how people should stop complaining the election results.   

Please use capital letters, commas and full stops when trying to make an argument about you not be uneducated. I re-blogged one of your posts, but you are the one who is in my in box? Just sayin’. You also sent some nasty replies, so I could see them; but not reply to because you deleted the original post. However you are the one calling me immature? Yeah… About that…

Also it is fair enough not being annoyed, if you are okay with the result then good for you. But then why make posts telling people to shut up about it? Tagging in the space were people are expressing their anger? people have a right to complain and express themselves, you go hey shut up guys you only sad because your team lost. When that is really not the fucking point of the complaints. Is only going to attract attention. 

Yes this is the system we have had for years. However this election has really shown how much it doesn’t work more than any other. It is no longer a two horse race. It is also a system were people’s votes are not of the same value because of the constituencies. But hey we shouldn’t complain about the things we see wrong… Nope… Not at all…  

People can judge for them selves how stupid you look, it is why I re-blogged today’s post. If you don’t look stupid then why care I re-blogged something you said? Does it really matter?

He is also not going to try and improve the country. He is going to make the rich richer, the poor poorer; and probably fuck up some pretty major things. Like he fucked up selling the Royal Mail off so bad it is not even funny. Not even Thatcher would sell the Post Office because it bared the Queens face. It was also making a profit, but yeah totes great idea to sell it when it is making the government money.

I am not attacking you. Tumblr is a public platform and I can reblog what I like basically, and after our “debate” yesterday I felt it was worth re-blogged what you posted today. To make you look like more of an ass, since you did a great job of that any way. I don’t know you personally, however I am judging you off your actions and the way you spoke to me yesterday.

I just reblogged one of your posts, with short comment saying I disbelieved what you told me yesterday. Since wow, that post you made today, makes you look even more stupid. You look like a clueless child, but will happily post comments in tags to provoke a response. Then complain when you get one. 

Since you do look petty and childish, with the shut up you are just sore losers; and you seem to defend David Cameron a lot. Which to be honest makes me not believe you. When I have tried to explain my actual issue with what has happened. You have not and just been like, well nah, nah, nah you lost. 

However who you voted for does not change my views on you. Since well we currently don’t have a working democracy. If you have voted Conservative but, saw the problem with the voting system. We would not be having this discussion. I would have zero issue with you because it is your democratic right to vote for whoever you feel will do the best job at running the country. 

I just have a problem with the fact you seem to think people who are currently complaining about the fact that even though the Tories only got 36% of the actual votes the gained fill control over the country. If they would have gained control through a coalition with another party with that, it would not have sent the shock waves it did. No one expected any party to gain full control.      

If your voted Lib Dem, then why are you not against what happened with the election? Since they got an unfair amount of seats to the number votes they actually got? The got 7.7% of the votes but only 1.2% of the seats. Please refer to this voting reform website which shows the figures: https://secure.avaaz.org/en/uk_electoral_reform_locb/?tJTGrjb

This is the point me an others have been trying to get across to you, but you claim to support one of the parties that has in the past suffered the most over our current voting system. That makes no sense?
