Here is another portion of the nebula known as IC1318 (see previous post). Since learning how to image remotely I can know image for longer periods of time from the comfort of my living room! Woohoo ! No more bugs to bother me and I can doze on and off at my leisure!
This is a stack of 84 two-minute images
Total time: 2 hours 48 minutes worth of exposure time

This is Messier 13 (M13) in the constellation Hercules. It is about 22,000 light years from us and is about 84 light-years in diameter. M13 is composed of several hundred thousand stars and it is possible to see it with binoculars in the night sky.
Notice the color of the stars...blue stars are much hotter than yellow or orange colored stars, just like as gas stove's blue flame is much hotter than a candle's yellow/orange flame.
Notice that in the upper right hand corner is NGC 6207, a dim 12th-magnitude edge-on galaxy which is about 30 million light-years from Earth.
I took this image this past week with a 480mm f/6 refractor telescope.
