Description

Heart of the Heart Nebula IC1805

8 x 20 minute exposures in hydrogen-alpha, capturing the glowing gas clouds in the centre of the Heart Nebula.

In the centre of the nebula is a structure called Melotte 15. It is an OB association of very young hot blue supergiant stars that is only 1.5 million years old. Fierce stellar winds from this cluster have blown the enormous bubble within the parent HII nebula that is the heart nebula. The winds have also sculpted the dust clouds within which other stars are forming into interesting columns and shapes.

The next step is to capture some more Oxygen and Sulphur data, to add to some data that I captured in January this year. I can then build a false colour image.
