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.

A 1998 complaint about Sandusky showering with a boy – one of those who testified against him – was investigated by university police but no charges were filed. McQueary witnessed a different incident involving "Victim 2" in the team shower in 2001 and notified Paterno and other high-ranking school officials, but police were not called.

I was wondering if you ever thought of changing
the structure of your blog? Its very well written; I love
what youve got to say. But maybe you could a little more in the way of content so people could connect with it better.
Youve got an awful lot of text for only having one or two
pictures. Maybe you could space it out better?

I have been browsing on-line more than 3 hours as of late,
but I by no means discovered any fascinating article like yours.
It's lovely value enough for me. Personally, if all website
owners and bloggers made just right content as you did, the web will likely be much more
useful than ever before.
