This picture does not look very spectacular, but still i am very happy with it.

At the core of this galaxy is a supermassive black hole with an estimated from (3.5 ± 0.8) × 109 times the mass of the Sun[50] to (6.6 ± 0.4) × 109 M☉.[50] This is one of the highest masses known for such an object. The relativistic jet of matter emerging from the core extends at least 1.5 kiloparsecs (5 thousand light-years) from the nucleus of M87 and is made up of matter ejected from the galaxy by this supermassive black hole. This jet is highly collimated, appearing constrained to an angle of 60° within 0.8 parsecs (2.6 light-years) of the core, about 16° at a distance of 2 parsecs (6.5 light-years) and an angle of 6–7° at a distance of 12 parsecs (39 light-years).

I wondered, if i could make this jet visible with my humble gear and a DSLR. FL seemed to be critical and so my Mak came in handy. The Insert is made of short (60s/ISO 1600) subs made with this scope. F/12 was good, since it prevented the core from burning out. The overview was made with my Newton. Well the jet is - at the insert - visible, but one has to look closely.
