Found some data for NGC 5694 today. This is the core of the globular cluster. I haven't bothered with globular clusters before but this one seems to have rarely been processed. The problem I have with globular clusters is that they all look the same to me. I know they cool things and we can learn a lot from them but at best they look like gems without the animated sparkle and at worst I once seriously thought one was a pile of salt on black velvet. Apparently they are very rewarding to view directly through a telescope. I wouldn't know. :(

I used the f170w data in the blue channel to represent ultraviolet. Hopefully I'm not mistaken that it's UV. All the information I could find on it indicated it was such. So anyway, some of the stars are very blue and that's why.
