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.

1993年 - 1996年の山形県の場合は、山形テレビがFNN/FNSを脱退→ANN系列に転向し、空白県となったため、フジテレビ山形支局の技術協力と、アナウンサーや技術スタッフの一部を仙台放送から派遣を受ける形で山形市内のホテルに特設会場を設けて伝えたことがあった。この番組も番組制作費の一部が『FNN基金』から捻出されており、フジテレビが制作幹事局ではあるものの「FNN加盟各局の共同制作」という位置づけとなることによる。地方局アナウンサーの中には、その後フリーとなってこの番組を改めて担当することになった人物（梅田淳、石原敬士など）もいる。その後も白星を伸ばし、12勝1敗で迎えた14日目に同じ12勝1敗の正代との大一番に土俵際の突き落としで勝つと千秋楽では何と幕尻力士として大相撲史上初となるこれより三役に登場し、これも幕尻力士として大相撲史上初となる千秋楽結びの一番に登場して大関・
