Hey, giving up looking through my own scope to guarantee its launched? I'll make that sacrifice. I'll just look through all of your scopes at star parties...

Just one? The James Webb.

LOL, it's primarily an ifra-red instrument, and I don't think it would even work in a non-zero-G environment. Too, I'm sure the image plane is huge in comparison to your pupil diameter. You could never use the full aperture visually.

Kim, a long time ago there was an article in S&T about what the human eye would be like if optimized for night-time use. The illustration was kinda creepy. If you get a huge pupil diameter, you need a larger diameter eyeball so that the retina can be appropriately curved to match it. I suppose the brain would have specialized image-processing abilities too, though. _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Send messages to the list to Utah-Astronomy@mailman.xmission.com The Utah-Astronomy mailing list is not affiliated with any astronomy club.
