Advice for stirring your online community and fostering engagement
When you enter into any new area of science, you almost always find
yourself with a baffling new language of technical terms to learn before you can converse with the experts. This is certainly true in astronomy both in terms of terms that refer to the cosmos and terms that describe the tools of the trade, the most prevalent being the telescope. So to get us off of first base, let’s define some of the key terms that pertain to telescopes to help you be able to talk to them more intelligently. The first area of specialization in telescopes has to do with the types of telescopes people use. The three designs of telescopes that most people use are the Refractor, the Reflector and the Schmidt Cassegrain telescope. The refractor telescope uses a convex lens to focus the light on the eyepiece. The reflector telescope has a concave lens which means it bends in. It uses mirrors to focus the image that you eventually see. The Schmidt Cassegrain telescope uses an involved system of mirrors to capture the image you want to see. A binocular telescope uses a set of telescopes mounted and synchronized so your view of the sky is 3-D. Beyond the basic types, other terms refer to parts of the telescope or to the science behind how telescopes work. Collimation is a term for how well tuned the telescope is to give you a good clear image of what you are looking at. You want your telescope to have good collimation so you are not getting a false image of the celestial body. Aperture is a fancy word for how big the lens of your telescope is. But it’s an important word because the aperture of the lens is the key to how powerful your telescope is. Magnification has nothing to do with it, its all in the aperture.

This design is incredible! You obviously know how to keep a
Comment Linkreader entertained. Between your wit and your videos, I
was almost moved to start my own blog (well, almost...HaHa!) Wonderful job.
I really enjoyed what you had to say, and more than that, how you
presented it. Too cool!

Have you ever thought about adding a little bit more than just
Comment Linkyour articles? I mean, what you say is important and everything.
Nevertheless imagine if you added some great photos or video clips to give your posts more, "pop"!
Your content is excellent but with pics and video clips, this
site could definitely be one of the very best in its niche.
Good blog!

After shaking hands - it was the first time they had met - the pair debated policy before moving onto more personal attacks
Harris said people leave Trump rallies early "out of exhaustion and boredom" - he said people don't go to hers in the first place

Trump criticised Harris's record on immigration and the border, and also her shifting policy positions - Harris blamed him for "Trump abortion bans" and for the 6 January attacks on the US Capitol
Snap polls suggest Harris won the debate, but Trump says afterwards that she "lost very badly"
With the election taking place on 5 November, Harris is slightly ahead in national opinion polls - but polls are very tight in key battleground states
Shortly after the debate, Taylor Swift endorsed Harris on Instagram, calling her a ''gifted leader''
