I am still playing around with mosaics.  Here's the Ring Nebula and Beta Lyrae area. The brightest star in the Beta Lyrae area is named Sheliak.  It is actually two stars orbiting each other every 12.9 days.  They are hot blue giant stars that are 4600 times brighter than the sun.  The star at 8 o’clock is also a double star system which orbit each other every 4.35 days and is 80 times brighter than the sun.  The star at 12:00 is part of the group which all together is approximately 960 light years away.  The other three stars just happen to be in the same line of sight.

Thanks, Steve! 

 

A great image and wonderful explanation!  I have not thought of those two objected in the same field, though they apparently are with the right equipment.

Thanks for the compliments!  I am sorry but I did leave off the fact that this is a mosaic of 2 panels.
