happy new year all.
the region between the 2 blue festoons was blazing away through medium to heavy fog.
you can also see a recent storm in the southern equatorial belt (white patch to the right of the lower of the two thick tan bands)

best 4 of 9 capture attempts over a 10 minute period.
the image was upsampled 3x, processed then reduced to 50%, so 1.5x from native.
conditions have been tough recently, either terrible seeing, clouds or heavy fog. i've often noted the seeing can be excellent when it's foggy, but there's usually a very short window to image before total fog out, with the challenge of massive dew formation. this one was captured through breaks in the fog with the dew heater on max. The region was never totally clear and completely fogged at times. had to feather the exposure time during captures to keep the exposure reasonable. The lowest exposures were still 3x that of a clear night, going up to 10x. used virtualdub to delete overexposed frames (PIPP didn't work).
