M45 the Pleiades or The Seven Sisters

M45 is found in the constellation of Taurus, Made up of around 1000 member stars its one of the closest star clusters to Earth at only 444 light years away. Dominated by young blue stars (75-100 million years old) its a reflection nebula caused by dust reflecting the blue light.
Its often called the Seven Sisters from Greek mythology but as you can see there are more than 7 bright stars. The image below shows the seven sisters and their parents (Atlas and his wife Pleione).

The Heart nebula IC1805

With my unmodified Canon 40d I almost didn't bother to image this nebula. Although its not going to win any awards but you can see some red nebulosity and make out its distinctive shape.
Discovered in 1787 by Friedrich Wilhelm Herschel its 7500 light years away, located in the Perseus arm of our galaxy in the constellation of Cassiopeia. Its apparent size is 1 degree by 1 degree and its apparent magnitude is 6.5.
The bright stars in the middle making up a open cluster are called Mellote 15, some of which are 50 times the mass of our sun, driving the intense red plasma of ionised hydrogen and free electrons.. At its centre are two stars locked in orbit, doomed to fuse together and explode in a supernova in 700 million years, making the unique shape of the nebula .
I used 26 x 3 minute exposures at ISO1000 guided with PHD2.
