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.

|If you have problem with frizzy hair, do not use a towel to rub your hair after shampooing. You will just damage your hair and make it frizz more when you do this. You are just going to want to cover it with a towel and push down to get moisture off. When you are happy, brush and comb your hair.

}{When you want to look slimmer, avoid stripes which run horizontally. These stripes will give the illusion of widening and this is not the look you want to achieve. Instead, wear a vertical stripe pattern that will make you look tall instead of wide.

|When packing your beauty kit, be careful you don't over pack with makeup. Choose things that you are drawn to but that also fit the tone of the season. Keep in mind looks for both nighttime and daytime wear. Just as with numerous other products, makeup can turn sour once it is opened. Bacteria can also form over time.
