Anyone interested in what goes on 'out there' -- and that includes most of us -- should read 'Backyard Astronomer's Guide' before plunking down any money on binoculars, telescopes, eyepieces, or surplus Saturn V rockets. The proud papa of a new telescope, I had about 50 questions that were apparently unanswerable, such as, How much magnification can I get with my 'scope, and how do I increase the optical power without degrading the image quality; Why do stars look twinkly and fuzzy, instead of the prescribed pinpoint of light; How do you decide on a good set of binoculars; and, how do I test and fine-tune the optics of my telescope?
And then I found this book. 'Backyard' answers all those questions and more. Messieurs Dickinson and Dyer apparently felt that there were enough star guides and atlases; what was needed was something that would tell people in practical terms how to choose, use and care for the equipment necessary to see all that stuff out there.

The price of the bundle including the eyepiece/filter set, and motor I think is a sweet deal, and a good idea if you have never owned a scope before.
Now being ignorant it took me over an hour to put it together. The instruction book it came with seemed like overkill so just find a youtube video and you can get it all working in a reasonable amount of time. It took me so long because I was unfamiliar with everything, and it probably wouldn't be as tricky for someone with more experience. I didn't even bother with the finderscope it comes with (based on dozens of reviews I've read) and got another Celestron model to put on it.
Took me a minute to take off the old one, figure out the new one and mount it with some double sided foam tape, but I aligned it pretty quickly. Celestron Star Pointer Finderscope.

A study led by a University of Utah astrophysicist found a new explanation for the growth of supermassive black holes in the center of most galaxies: they repeatedly capture and swallow single stars from pairs of stars that wander too close.
Using new calculations and previous observations of our own Milky Way and other galaxies, "we found black holes grow enormously as a result of sucking in captured binary star partners," says physics and astronomy Professor Ben Bromley, lead author of the study, which is set for online publication April 2 in Astrophysical Journal Letters. "I believe this has got to be the dominant method for growing supermassive black holes," he adds. "There are two ways to grow a supermassive black hole: with gas clouds and with stars. Sometimes there's gas and sometimes there is not.
We know that from observations of other galaxies. "Our mechanism is an efficient way to bring a star to a black hole," Bromley says. Munching Binaries: One is Captured, One Speeds Away. Biocentrism. Ernő Rubik. Ernő Rubik (Hungarian: [ˈrubik ˈɛrnøː]; born July 13, 1944) is a Hungarian inventor, architect and professor of architecture.
He is best known for the invention of mechanical puzzles including Rubik's Cube (1974), Rubik's Magic, Rubik's Magic: Master Edition, Rubik's Snake and Rubik's 360. Life and career[edit] Rubik's Cube In the early 1980s, he became editor of a game and puzzle journal called ..És játék (...And games), then became self-employed in 1983, founding the Rubik Stúdió, where he designed furniture and games.
In 1987 he became professor with full tenure; in 1990 he became the president of the Hungarian Engineering Academy (Magyar Mérnöki Akadémia). At present he is mainly working on video game development and architectural topics and is still leading Rubik Stúdió. He is known to be an introvert, barely accessible and hard to contact or to get hold of for autographs. Rubik is a member of the USA Science and Engineering Festival's Advisory Board.[6] Prizes[edit] References[edit] Celestis, Inc. - Memorial Spaceflights - Launch ashes into space - Space burial - Funerals in space - Unique Post Cremation Option.
