I just noticed something interesting about the ability of ads to match the content of a page. I was reviewing my blogs on Astronomy to determine what I should start working on for my next endeavor. I was surprised when the ad banner at the top of the page showed the following!

Well, it's been a while (like almost a month), but then again, no one has complained. So here we go with telescopes. Although the tube (actual telescope), is very important, the mount is equally important. They fall into two basic categories, altazimuth and equatorial.
Altazimuth allow changes in altitude (up and down) and azimuth (around and around) similar to a camera tripod. One very popular mount is called the Dobsonian named after a California amateur astronomer, John Dobson.

As some of you know from posts in our clan forum and in "Off Topic", my great nephew Zachary (3 years old, I have found out, not 4) had to have brain surgery for Chiari Malformation (http://www.2old2play.com/modules.php?name=Forums&file=viewtopic&t=47627&highlight=chiari). Well, he had the surgery on Monday, September 29th and I'm extremely happy to say that it appears to be successful.

OK, so I lied! I had ended the last blog with "Next time I'll look at the 3 types of reflectors and give some examples of the prices of some popular models (two of which I have plus one that is on loan to my brother)."
Instead, I find I need to cover just a little bit more on terminology and on the types of telescopes.

Some info on telescopes. The purpose of a telescope is to really to do two things, not just one.The first is to magnify the image which is the obvious one. The other is to increase the amountof light which reaches your eye. The magnification is a result of the focal length of the lenses involved. THe amount of light that reaches your eye is based on the size of the primary lens OR mirror.
