Taken with 92mm TMB apo refractor and Borg 0.85x flattener/compressor, and Canon 5D MkII camera at ISO 400 for stack of 4 exposures x 10 minutes and stack of 2 exposures x 2 minutes (for the core) blended in Photoshop with layer mask. (Photomatix HDR did not work -- images did not align, due to field rotation?). North is up in this vertical orientation.
