This is a layered stack in Photoshop, first try, but it is not good enough, still lots of detail are visible.
The same stack, now processed with Photomatix to get a very soft result with details from core to the outer edges.
This is a 50% size image.
My first attempt at a mosaic, August 12, 2007. Some seams are still visible and the core is burnt out, so I will have to do it again! The complete mosaic is 17 MegaPixels.
4 tiles of 3 stacked exposures of 3 minutes each made at 1600 ISO with a modified Canon 350D, and a 20-cm (8") f/2.75 ASA Astrograph.
