Description

Version A is a very rough and ready go of the luminosity data. While calibrated and stacked, it has only been cropped to eliminate stacking artifacts and then stretched. There has been no noise reduction, DBE, deconvolution, etc.

Version B is more carefully processed Luminosity data.

Version C is more highly stretched than version B.

Version D utilizes the color data that was collected.

Version E is an annotated version of D.

Version F is a 2000x1500 crop of version D.
