Hello Astronuts,

Finally got around to processing the heart of the Heart nebula, IC 1805. This was a difficult image for me because of continual thin clouds that prevented getting some of the fainter narrowband data. I managed to shoot 10.5 hours of H-a but only 3.5 hours of OIII and 5.5 hours of SII. The latter two took a lot of noise reduction to bring in. Fortunately the main detail is in H-a, so I used that for a small amount of Luminance. Most of the frames were imaged unguided, the other half was guided.
