Object name: IC1805 Heart Nebula
Apparent RA:  Apparent Dec:
Constellation: Cassiopeia

Here is an image from a long time ago. During 2007 I used my complete set of narrowband filters to collect a lot of frames of the central region of the heart nebula, and this is my first attempt to combine them in to a tricolour narrowband image. SII is red, Ha is green and OIII is blue. Some further processing needed to flatten the background, but that can wait until I remember how!
