m13 cluster

[jaspalchadha]

M13, the Great Cluster in Hercules, teeters on the edge of naked eye visibility and appears in binoculars as a small, circular, hazy glow. It contains over 300,000 stars, and its luminosity is 300 thousand times the Sun.

Globular star clusters, unlike open star clusters such as the Pleiades, are tightly held together by gravity. Whereas open clusters break up after hundreds of millions of years, globular clusters remain intact after billions of years.

Nice capture. I like the galaxy you captured to the left of the cluster. It is not NGC 6207 (which is a bit further out)

Nice image of this popular globular.  @Michael - after a bit of detective work, I *think* the galaxy might be IC4617

You are right, that is definitely IC4617

Jaspal, you always get lovely coloured stars without burnt out centres - what's your secret?)

[jaspalchadha]

Thanks all one of my favourite clusters.. Stub. Just work with layers and slow increments ..

Just seen this, great image! The "propeller" shows plain as day in there, very nice.

Lovely sharp image, nice star colours.

really well done !

Congrats on getting the propellor, easily lost if a layer mask isnt used to increase the dynamic range.

Great image. Having seen it, I can't wait for M13 to swing round again for a proper look at it.

Smashing image, looks almost 3D.
