I'm looking for a planisphere (I'm at 30 N lat.) that correctly shows the sky above when lying flat on my table. The ones I have require you to hold them over your head to obtain the correct orientation for stars. For example, I want to be able to look down at the planisphere on the table, see that Polaris is 30 degrees above the horizon, and geographically North from me, and then look in the sky to the North, up 30 degrees, and find it. In other words, if I punched holes for all the stars on the planisphere, and put a light underneath it, it would project the correct location for stars on my ceiling. Is there such a thing? Thanks, --Gary
