CLAHE is good for the Moon
CLAHE stands for Contrast Limited Adaptive Histogram Equalization, implemented as plugin module for ImageJ.
Suggested by Bushman.K it was found to be not quite compatible with the solar images, but works well on the Moon :)
The lunar image of 04.07.2015, around 23:30 MSK, taken with TIS DMK23 via 2x Barlow on Meade series 6000 80 mm f/6 triplet refractor.
Panoramic image of six panels, 20% of 1000 (ok, 200) frames stacked, stitched in MS ICE, deconvolved (AstraImage Richardson-Lucy, Cauchy, 0,3-9), wavelet-sharpened (1-10-15-5-1), CLAHEd in ImageJ (127-255-2), wavelet again (1-5-10-5-1) and some contrast added in PS.
Note: the white square is the histogram trap for deconvolution to correctly normalise the processed image. I was finally able to save Aristarchus from becoming saturated.
