Heart Nebula collection

I collected my images of the Heart nebula in this blog post. Most of the images are reprocessed with my new method. This new technique will provide better color handling, softer look and high details at the same time.

I have shot many targets with instruments of different focal lengths, this makes possible to show the fractal nature of our universum,  more and more details shows up as focal length gets longer.

Be sure to click the images to see them at full glory.

The "Heart Nebula", IC1805 locates about 7500 light years away in constellation Cassiopeia. This is an emission nebula showing glow of ionized elements in a gas cloud and some darker dust lanes.
In a very center of the nebula, lays Melotte 15, it contains few very bright stars, nearly 50 times mass of our Sun, and many dim ones. The solar wind, a radiation pressure, from massive stars makes the gas twist to a various shapes.

Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.
