I still insist that the David Chandler planisphere is the best, for a number of reasons. While not unique to Chandler's, the white background and dark text make reading the small print easier for me than on those planispheres that use a dark background with light text. (Craig, maybe your red light, or whatever other colored light you use at night is just too bright.) But the best part of Chandler's planisphere is the reverse side that depicts objects in the southern sky without the distortion of planispheres that do not have this feature. Finally, a word in favor of all planispheres: I've never had one break when I've dropped it.

Computerized devices will certainly replace paper/plastic for most people. I like the ease of use of a planisphere but there are things I don't like: - Too small and too distorted. I tried the large David Levy one but it doesn't store easily in anything, and the white background ruins night vision (more than a computer screen I think). - Most have glare and are difficult to read unless you get the light just right. My eyes are getting worse which doesn't help. My current favorite is the Sky and Telescope one. It's also just a bit large though; I haven't tried Orion's, but I've tried several others and have been very disappointed. For years I've wanted to make a tablet-style computerized planisphere. The farthest I got was to create something in Excel. The main reasons I like them are: - The entire real estate of the device can be used to display just what you want, so you get a much larger image and it's not as distorted. - You can adjust what it displays. You also get planets. - You can adjust the magnitudes of what it displays to better match what you're looking at. I've tried a couple phone versions and they are just too small. To me the iPad or another tablet PC is perfect. Screen contrast continues to improve, especially with LEDs, so that should help night vision issue. Some programs are better than others in this area as well.

I'm kinda of on an astronomy kick since the weather continues not to be good for visual observing. So I just got done reading an article that talks of learning the constellations and the article got me thinking. I learned the constellations with a planisphere and from time to time I will still use one. However, in the article the author talks how he had a group of novice astronomy students out and each had a copy of the Edmund's Scientific Planisphere. Some also had SkySafari, StarMap and Distant Suns on their cell phones and they found the constellations and objects far quicker than those using the planisphere. Thus the author came to the conclusion that cell phones and apps are probably on the verge of replacing the planisphere as the tool used for finding constellations and other deep sky objects, especially for the younger generation. One of my observing friends is in his 20's and he uses Distant Suns in the field all the time. So the question I ask is do you use a traditional planisphere (and I could say atlas since some of these aps go down quite deep) or are you still an old book, atlas, planisphere type of guy? It also leads to an interesting thought which is what will be the tools of the amateur astronomer say in 20 or 30 years? -- Jay Eads _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php Visit the Wiki: http://www.utahastronomy.com ----- No virus found in this message.
