Hi everyone,<br />I have a somewhat odd request to make. I need a picture of a magnitude 1 star amongst a starscape. The picture needs to be exactly as it would be seen by the naked eye, and there needs to be no light pollution, moonlight, air pollution/smog, clouds etc.<br /><br />The reason why I am asking relates to a bit of research I am doing about the Titanic disaster and the proximity of a ship alledgedly close to the disaster. My website is currently down for maintenance, but there is a google snapshot (sans images) here:- <br /><br />http://64.233.183.104/search?q=cache:Nm4FPLJRwOoJ:www.btinternet.com/~dr_paul_lee/TitanCalif2.htm+Titanic+Californian+Paul+Lee&hl=en&ct=clnk&cd=7&gl=uk<br /><br />(sorry for the long url!). A friend has posted that a ship's masthead light, under perfect viewing conditions, can be seen at 17 miles+, and is the same brightness as a magnitude 1 star- see posts #17636, 17639, 17655, 19008 on<br />http://titanic-model.com/dc/dcboard.php?az=show_topic&forum=100&topic_id=17582&mode=full<br /><br />I'd like to show that a mag 1 star is visible with an image as proof. <br /><br />Thanks in advance for your all help<br /><br />Paul<br />

I don't have a picture for you, but you don't need a picture to prove that a magnitude 1 star is visible. In the entire sky, there are only 16 stars that have magnitudes lower than 1. Spica in Virgo, with a magnitude of 0.98, is the closest you can get to an even magnitude 1 star. The next brightest is Pollux, in Gemini, with a magnitude of 1.14. These stars can be seen even in severely light polluted skies, even with a full moon nearby them.<br /><br />The North Star, by comparison, is only a magnitude 2 star. And certainly people have seen that!

Or again,<br /><br />The BRIGHTEST star in the Big Dipper is Alioth, which is "only" magnitude 1.77

If correct that the mast head light appears as a first magnetude star at a distance of 17 miles, then a person very familiar with the constalations would notice the extra star, even though it is barely above the horizon with a red tint. Persons moderately familliar with the constalations and planets likely would not notice. Neil

A little behind in your reading Neil? <img src="/images/icons/smile.gif" /><br /><br />Thanx for the tidbit about 17 miles. I assume that's 17 nautical miles <img src="/images/icons/wink.gif" /> under best case conditions. <br /><br />Anyone out on the sea at night better darn well be familiar with the constellations!! <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
