Thought I would rework the data of the Heart Nebula IC1805, I have managed to obtain some darks and bias frames. So I loaded everything into Astro Pixel Processor and started the registration and integration process. I’ve now discovered that there must have been some alignment issues during capture as there is a distinct rotation artefact in the top left frame. Still, this one has more contrast, and we can see more detail than before.
