Description

The image of the Heart Nebula (IC1805/NGC896/SH2-190) is displayed using the HOS palette, where Ha is assigned red, O3 green, and S2 blue, with two sets of livestacked exposures being used for each filter: 90 x 1 minute + 15 x 2 minute for Ha (120 minutes total), 60 x 1 minute + 10 x 2 minute for O3 and S2 (80 minutes total x 2). The six livestacked exposures were again restacked to produce the final image (280 minutes or ~4.7 hours total integration).
