NASA Worldwide Telescope Usage Survey

NASA want to know more about where and when astronomers are using their telescopes. The reason is because they're concerned about the increasing use of satellites to perform LIDAR scanning of the earth (LIDAR is like radar but with lasers). The lasers are well within the safe limits against people accidentally looking up when they're scanning, but they want to know the relative risk of telescope users getting more light in the eye than they're ...

Have been browsing this site for a few weeks and finally decided to join. Hopefully I can get information on astro-imaging thru an early Celestron CCD. However I just enjoy astronomy as a whole, whether its thru a scope or just looking at the sky.

If you divide the brightness of the uneclipsed photosphere of the sun by the brightness of the chromosphere that can be seen around a totally eclipsed sun, what is the result? (Obviously when I use the word "chromosphere", this should not be confused with the corona.)

I am having difficulty finding the necessary information on the Internet in order to ...

She is also a keen birdwatcher, so one that can be used for that too, would be great. However, if it really meant she wouldn't get such a good view of the night sky, then we may reconsider this aspect. ...
