HomeStar - 21st Century Home Planetarium Review 98

Jeff writes "Direct from Japan, the SegaToys HomeStar is a unique home projector that turns any room into a planetarium, giving a clear view of the night sky. Using interchangeable plates, it's capable of displaying up to 10,000 stars of either northern or southern hemisphere, as well as their constellations. The starfield can move on a timer to simulate the earth's rotation. Also comes with a meteor generating function and sleep timer. Makes a great gift for the dad who has everything, or people who live in light-polluted areas." Check out Jeff's review of the unit.

      Yeah, seriously. Who is going to use this? If you want to see the stars, just get out. If you want to see many stars, just go for a drive to a nice quiet place outdoors, it is really relaxing. What's the use of projecting stars to your ceiling? You might as well get a disco ball and shine some light on it.

        I live in central Osaka. If I had a car (and most people here do not, with bikes and public transportation so convenient), it would be well over an hours drive eastwards to get out far enough to at least not be surrounded by street lights and pachinko-parlour neon.

        I live in a town of just 7,000 people, and the light pollution is so bad that the majority of stars aren't visible (yes I know the vast majority of stars in the universe are never visible, but you all know what I mean). For about fifty miles in any given direction of most major metro areas, only a few stars can be seen. I've only seen the night sky as it used to look a handful of times. It's interesting now to watch people who have never seen in person just how many stars should be visible.

          I'm 40 miles out from downtown Chicago, and about all I can spot anymore is Orion's belt. Some of the planets break through the city glow, too. That's pretty much it.

          I grew up in a much more rural region, and only after "citifying" myself did I realize how bad light pollution has become. Would be nice if it was feasible to do something about it.

          I agree. I believe many living in urbanized areas (and then such cities would be 5,000+ or close to such towns) would be quite shocked to see the night sky as it looks like with no special light pollution influences. I've seen it just a few times the past decade or so, and it's a fascinating sight, making you truly *see* how you're on a sphere floating around in space. :-) You know you're in such a place when you can spot our neighboring Andromeda galaxy as a fuzzy spot with the naked eye!

            • I was on a cruise ship, in the middle of the caribbean a few years ago. I thought I would be able to see lots of stars in the sky. However, the boat was decked out with so many strings of overhead lights that the stars were overwhelmed.
            • I had some pretty good stargazing up on the continental divide in Colorado. It's also fun to watch for satellites just after dusk.

            • During the aftermath of a hurricane in 2003, in a major metro area on the east coast US, *ALL* electric power was out the first night. I camped out in my backyard (the house had been flooded) and it was very clear. Laying on a blanket, with AM radio reporting the latest news, unable to get to sleep, the best entertainment was the sky - never had it showed up so clearly, the milky way, a few shooting stars, etc. I even spotted what must have been a satellite, a very faint dot moving very quickly across the d

        • My apartment overlooks a major shipping port and industrial/manufacturing area (the Port of Tacoma and the Tacoma Tideflats as well as Fife Washington) if you wanna see some light pollution you should come over sometime.

          Oh well though, my 10' dob cuts through all that fairly well if I'm feeling to lazy to drive out to the boonies and just wanna drag it out onto the balcony.

I live in a 'burb of a big city and the light pollution from the city (~ 20 miles away) is so bad that that I usually don't even need the lights on outside at night to see in my yard: the yellow-orange haze from the city is more that sufficient illumination.

I think the only way the local observatories are able to work is that they have sodium filters to filter out most of the street lights.

    After reading up and correctly identifying every constellation in both the northern and southern hemispheres, I was kidnapped and transported against my will to the Credence system where I was then press ganged into service for the Unitarians as the so-called "Last Starfighter". It was a harrowing experience; I barely defeated their leader, Xenu, in a last-ditch attack with the Yellow Submarine's emergency weapon system, "Mortal Flower". After a long, boring awards ceremony, I was transported back to Earth. Nobody believed me when I told them my tale, of course, because I had been on acid at the time.

    Unfortunately, I've only had perhaps a dozen chances to look at a good, dark sky in my lifetime. But, fortunately, I have had those chances.

    It's unreal. Just as it's hard to recognize the constellations from your typical U. S. suburban location, because you see too few stars, under good conditions it become hard to recognize the constellations because you see too many stars. The brighter stars that form the H. A. Rey connect-the-dots diagrams are lost in a sea of stars that look almost as bright.

    I had a real "Aha!" moment on one of those occasions.

    We've all been brought up to believe that the constellations are connect-the-dots stick-figures. And most of these stick-figures are so lousy that it's hard to believe anyone ever connected them with anything. There are a few exceptions, like Orion. (H. G. Wells wondered why the Christians had allowed the constellations to continue to be named after pagan mythology, and had never reinterpreted them. He figured that in any such interpretation Orion would be Christ...) Sagittarius does have something that perhaps can be seen to resemble a bow. But, mostly, they are a bunch of slightly-out-of-true triangles and boxes.

    Well, one night, when the sky was full of, what can I say but stardust, I suddenly had this perceptual shift, like seeing a Necker cube reverse. I didn't see dots. I saw a silvery, stippled texture. And the sparser and denser stipples of starlight looked sort of like clouds. And, just as you see shapes in clouds... not connect-the-dots, stick-figure shapes, but solid, three-dimensional shapes... I saw solid, three-dimensional shapes, sculpted blobs of starry fog in which I thought I could see animals, and faces, and so forth, just as I can in clouds.

    I can't prove it, but I am certain that this is the way the ancients perceived the sky.

In Canada it's a bit better because there are still plenty of areas with low population density (less than 1 person per sq km). If you are searching for the best sky views, you need to be at least 30 miles away from any town or city and preferably no cloud cover at all - any cloud over a town will reflect light back at
