Epsilon Lyrae is one of those systems that would be pretty cool to live near. Two of the four stars are A class: hot, bright and about two solar masses rotating around a common center of gravity about 900 years. The other pair are another another hot A and an F class (so cooler and redder but still hotter than Sol) in another 1200 year pas de deus. Both pairs are rotating around a common center of gravity on a 250,000 period. I do not think either would have habitable planets for man but if they did, it would be quite a show.
At 15x, the Televue-85 splits them into two pair with both pairs showing some split. At 43x; the splits are more obvious.
It was so dark. After 20 minutes of dark adaptation as the rhodopsin regenerates, I could almost see stuff without my red headlamp.

ReplyDeleteSomething like Isaac Asimov's Nightfall, then?
Not quite that amazing. You would never have more than four stars in the sky at once. The distance between the pairs is still big. I am sure they would be visibly four stars.
