Re: [Utah-astronomy] Globular Cluster Blue Stars
That's a nice view. And it's notably blue. Thanks, Joe --- On Wed, 6/17/09, John R. Peterson <docpity@earthlink.net> wrote: From: John R.

Note the photo caption that states M13 has an "unusually low" abundance of blue stragglers. Yet Joe is right, it does look blue. I just don't trust published colors. There isn't any such thing as a "correct" color anyway. Color is a property that exists only in the human mind. On Wed, Jun 17, 2009 at 11:25 AM, Joe Bauman <josephmbauman@yahoo.com>wrote:
