Description

Elliptical galaxies are frustrating. They are gigantic but have so little structure that they just resemble fuzzy balls more than collections of billions and billions of stars.

However, M87 has one thing going for it...the jet that extends out of the galaxy from the region around the black hole. While this can't compare with Hubble's version, the jet is clearly visible at about 7:00 in the galaxy near its center. 

Processing was fairly simple because most everything I tried either had no effect or made things weird. 

Each R, G and B:
dynamic crop
deconvolution
DBE

L
dynamic crop
deconvolution
DBE
generalized hyperbolic stretch

H
dynamic crop
deconvolution
generalized hyperbolic stretch
starnet

RGB
channel combination
generalized hyperbolic stretch
channel combination in L
TGV Denoise
pixel math in  the clone

clone of RGB after TGV
starnet
NRGBCombination in H
MLT sharpening

The H-alpha didn't really add much if anything here. We'd have probably been better served just getting more L (though at the time when we got the H, the moon was fairly close to full).
