Audio-Video files for NYSkies Semiinars
    This page holds the audio-video files for our digital Seminars.  
Each Seminar has two files, named with the issue date (yymmdd), ending 
with 'a' or 'v'. 'a' is the audio file; 'v', video. For a made-up 
example, the files for our inaugural Seminar of 2005 March 17 are 
'050317a.mp3' and '050317v.ppt'. 
    Download the files to your computer for playing. Playing them 
directly from the web can cause chatter,skips, freeze.  Storing the files 
locally also allows you to play them away from the net and frees them 
for others to download. You may play the files at any time, not 
just on the issue date. 
     Set up the video file for its first picture and then start 
playing the audio file . The audio file prompts you 
to scroll to the next picture in the video file. The 
pictures are numbered for reference during the Seminar and 
for questions or comments afterwards.
    While there is n o live interaction with the sessions, you can 
put questions and comments to me thru the NYSkies email group at 

    To subscribe to the group, send an empty email (any text in it,

    The group is a general discussion forum for home astronomy, and 
not only for handling Seminar inquiries. Please put your notices and 
astronomy-related notices, news, questions there. 
    The files for the current and previous two Seminars are in this 
page below. Older ones are moved to offline storage. Be sure to keep 
those you want to play again in the future.
