After creating the Heart nebula in a mosaic a month ago, we had some semi-clear nights last week, in which I could try and stitch the Soul nebula to the Heart.
Unfortunbately these nights were also very foggy, sometimes fog banks floated over, with barely star visibility. The good news is that SGP (Sequence Generator Pro) kept up trying, despite star loss in PHD, to continue making lights. While sleeping. So that’s really wonderfull.
The end result, needless to say, did have that much gradient sin the final image that I do not consider it a result. It’s more an exercise. The final mosaic had 10.000×12.000 pixels and took 1,5 Gb TIFF or FITS size. Both AstroPixelProcessor and Photoshop had issues digesting this large file. In fact it’s so large that Astrobin or this website cannot upload it.
