This has been one of my dream targets since I began my journey in astrophotography.  A galaxy that is close enough to resolve stars, has detailed encircling dust lanes, and best of all a relativistic jet that can be imaged with amateur equipment!  

I spent the majority of my processing time trying to get the most I could out of the jet.  I found that the brightest parts were actually OIII while the Ha took up a larger area.  Doing an HOO version really highlights the structure of the jet and makes it appear that the dust belt encircles the core.  See my HOO version as one of the revisions.  Adding this data to the LRGB data was not simple.  I removed continuum Red from the Ha and Continuum Blue and Green (2:1) from the OIII.  But this brought down the signal level to incredibly low levels, revealing the limitations of my flats.  Lots of noise reduction and flattening the background finally produced clean enough linear Ha and OIII versions to add to the LRGB data.  I separated the OIII/Ha data between the galaxy and the jet.  The data was added to the galaxy at 50% strength and to the jet at 400% strength.  

BXT was used but I had to tamp it down to only a .24 strength.  Any stronger and the blue stars in the ring began to turn into "sharpening worms".  The dust could have stood up to a stronger BXT but I'd rather err on the conservative side with BXT.  

The starless version shows how the globular shape of the surrounding dust, gas, and stars presents subtle gradations.   A particularly interesting feature is a faint blue rope highlighting one of the edges of these envelopes.  The mouseover version is starless and shows this very clearly.

The overall slightly brown tint comes straight from SPCC.  I assume it is correct and resisted all temptations to a more neutral white balance.

As we've seen in the ESO images (https://www.eso.org/public/images/eso0903a/) there is massively more to be seen in Centaurus A than I managed to capture here.  I saw no evidence of the jet on the opposite side of the one I captured.  The more I stretched the data the larger the globe of the galaxy appeared.  Next year I hope to try again at F3 and with a wider FOV.
