Re: Planisphere question

Hi Jess,

Interesting proposal, there. I would think it fairly easy to make a planisphere adjustable for various latitudes.

I envision a chart within an outer shell; this shell could be adjusted +/- for a range of common latitudes.

It would be larger, probably rectangular, and it would be difficult to adjust the E-W "distortions" for everyone, that I think most dedicated planispheres are adjusted SOMEWHAT.

To hold the altitude, a compression slider(s) could be incorporated on a side bar. Just my thoughts, but nice idea.

Best regards,
Dave.
