    Re: Yet another modified 2102-D star finder
    From: Byron Franklin

    Byron: I don't see that you can better my 2 minute star finder.
    It's designed to be used by a 5-6th greader.
    The ease of taking the M/D & converting to GMT is on the disk.
    That is for 00:00 that day, you than add the GMT of observation,all done.
    To set up a sky, you rotate to set a star or body to desired AZ & ALT, read Aries pointer for GMT than substact GMT for M/D and you have GMT of time of ocurance. The accuracy, of using the nearest WEB horizon can be place on center pole interpolaed between degrees for LAT, Longitude for the web horizon can be interpolated for LONG on the outer disk.You Tube type(navtec333)navtec3331)is my videos on this set up:Earth, celestial and the two minute star finder,
    Tracking the sun,many ways of placing the sun on the star disk...with out the NA by rise/set/noon/with the NA. Midnight sun, how the circle the earth at high Lat. and different Dec. How to convert Local time to GMT See the Video on you tube.I only send your one close LAT for 20. rude star disk will also work for other LATS
