Heart Nebula (IC 1805) and IC 1795

El Cerrito, CA

IC 1795 is a bright nebula attached to the right side of the "heart" nebula, IC 1805.

The Heart Nebula, IC 1805, lies some 7500 light years away from Earth.
It 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. This nebula
is formed by plasma of ionized hydrogen (HII) and free electrons. The hydrogen has
been ionized by ultraviolet radiation from young hot stars at the center of the heart.
The nebula thus exhibits a characteristic red spectral glow (represented in this
monochrome image by white).

Image consists of seven 15-min exposures through a 7nm hydrogen alpha filter.
Scope: Tak FSQ 106ED refractor @ F5, 530mm focal length
CCD: SBIG STL 11000, CCD temp: -30C
Guiding: SBIG STV full exif

other sizes: small medium large original auto
