Hi Guys,
well well wellll looks like the jet is deep within the image

I think short burst exposure might reveal it even better.
Heres an inverted version. I'm not quite sure whether the jet has HA content?
Heres some info on M87:
M87 is an exceptional galaxy. Though of similar diameter to our own Milky Way galaxy, being spherical rather than just a thin disc in shape, it contains vastly more stars, several trillion in number. Deep exposure photographs show that it extends far beyond the 7 arc minutes shown in most photographs, perhaps to half a degree across. It is surrounded by a swarm of globular clusters. M87 also has a jet visible on short exposure photographs. This jet is an outflow of material ejected from the region of a supermassive black hole at the centre of the galaxy. The jet is the source of intense radio emission and thus M87 is termed a radio galaxy and has been given the name Virgo A.
