      Interesting you mention Chicago. I also live in Chicago, and have lived in the same neighborhood on the NW side for 22 years. Though it is far from an astronomer's dream, the city has made an effort to reduce light pollution over the past decade, and the improvement is very noticeable. 20 years ago, you could see almost no stars, occasionally some bright one would be visible. Now, many are visible on any non-cloudy night, especially if you go for a walk in a large park or along the lakefront.

      The city did not spend any serious amount of money on a retrofit, but instead put in fairly strict requirements on any new lights both on public property, as well as in the building codes for new private construction (especially parking lots). They need to light the street/lot well, but must limit the upword radiation directly from the light (within reason). Usually it is using pretty simple technology (reflective hoods, etc.). I think this stuff costs a little more initially, but pays itself off pretty quickly with reduced energy requirements.

      I do walk a lot around the city, often at night. I do appreciate the well lit streets and walks from a security standpoint. I appreciate the effort the city has made to balance the two opposing needs.

      Bottom line, I can't argue with your general point. If astronomy was my hobby, I would not find Chicago to be a good place to do it. But, it is a good example of how a common sense approach can not only save energy, but make it a better place to live. The light pollution problem has gone from pathetic, to mediocre. At least it is moving in the right direction, slowly. I hope the situation continues to improve over the next decade. I hope more cities go down the same road.

      Not necessarily. A city could do a great deal to minimize light pollution without sacrificing luminosity by replacing light sources from white halogen to amber, as well as concentrating that light exclusively in a downward direction with the aid of metal screens painted white on the inside; picture something like a tablelamb-style screen and you're there. This would get rid of glare while keeping the streets as well-lit as they are now.

      If implemented, less wattage is needed to achieve the same level of illumination, thereby saving the city a TON of money every single night from now until kingdom come, as well as wasting less energy resources, always a good idea in an age of fossil fuels.

      Hence, less resources spent - good for astronomy, good for the environment, good for the city, and so it goes. Imagine if every city in the world implemented this!

  28. Other free things that do the same job by jiawen · · Score: 1

    There's a lot of free software out there that will give better skymaps than most books can. After all, the sky changes from minute to minute, not just day to day.

    XEphem is my choice. The interface is pretty old-school, but the maps it prints out are perfect for my uses.

    KStars has more bells and whistles but, in my experience, doesn't print as well.

    As for advice on buying scopes, etc., check these places too.

  29. Geeks aren't the only ones up in arms... by j_stirk · · Score: 1

    Geeks aren't the only ones up in arms about light pollution either.

    You'll also find plenty of greenies getting upset about light pollution due to the effect it has on insects and birds (and hence, lots of other critters too).

  30. Southern hemisphere? by GrahamCox · · Score: 1

    Since the site is slashdotted into oblivion at the moment, can anyone tell me if it includes the southern hemisphere?

  31. How do they compensate for geographic location? by Shag · · Score: 1

    Software, and certain three-dimensional star guides, can compensate for location-based differences in the sky - e.g. Polaris is 45 degrees above the horizon if you're 45 degrees north, but not visible at all if you're 10 degrees south. Two-dimensional things, such as books, have a much harder time of this. Thus Planispheres come in several different versions, for different latitudes. In this e-book, there aren't charts. Although this book does include some good southern objects, there are still entire pages dedicated to things near Polaris, which reflects an inherent bias toward the northern hemisphere.

    Happy to be somewhere with a view from 90N to ~70S...

  32. coolest thing I ever saw by le+duf · · Score: 1

    One of them, at any rate. A few years ago, I was up in the Berkshires (U.S., not U.K.) and I noticed a really bright object close to the Moon. "Hey! That must be Jupiter!" I thought. Ran in, got a pair of binoculars, and tried to get it in view, using the chimney to block out the Moon. As soon as I found it, I noticed three bright pinpricks of light. Wow! Three of the Galilean satellites! I tried to get other people in the house to come out and look, but no one seemed all that interested. Losers.

    Hey! Just found out yesterday was the 396th anniversary of their discovery. Not bad timing for a /. post.
