OK, so I keep posting images of globular clusters. And maybe they all look ... similar. But I suspect I'm slightly obsessed with globs. I love their little differences. Also, I reckon if globular clusters didn't exist, and George Lucas had invented them as a special effect for Star Wars, we'd all say "No way! Get out of here! That could never happen".

Just now (8.30 - 8.50) processed in DSS with a quick stretch etc. in PS

Don't apologise, Jonathan, I like them too. Great photo.

I like globs, too-nice image!

Thanks guys. I keep wondering what the night sky might look like from a planet orbiting a star in the centre of a globular cluster. How might those guys think about the universe?

RayBan sales would be up...!

Fascinating little universe we live in.

If you haven't already, you need to read a classic short story by Isaac Asimov called "Nightfall", about just that scenario. A planet with three suns which is permanently in daylight except once in several millenia when an eclipse by a dark body lets people see the stars for the first time.

Nice image btw.

That's right, I remember now! I read it as a child. It might have been at the back of my mind when I made that post.

Nice! Keep the globs coming! :)

The background is a little grainy - you might want to consider darks and bias frames to help get a blacker background.

Go the Canberran imagers!!

I'll keep 'em coming.

It has darks, flats and bias - but the darks were scaled from a different exposure tie which never works well ... I'll reprocess and repost.
