The heart of the heart nebula

 

The Heart Nebula, IC 1805, Sh2-190, lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula showing glowing gas and darker dust lanes. The nebula is formed by plasma of ionized hydrogen and free electrons.

The nebula’s intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula’s center. This open cluster of stars known as Melotte 15 contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun’s mass. The cluster used to contain a microquasar that was expelled millions of years ago.

Last night I succeeded in imaging the heart of the heart nebula with a TEC-140 on an EQ-6 mount. Off axis guiding was used for the 4,5nm 30min h-alpha images.

For the image 9×30 min was used…

I think this forms a nice base for a hubble palet image…
