Visible plasma jet in M87?


A few weeks ago(April 9th), there was a One-Click Observation of Messier 87 with the CHI-1 telescope (Planewave CDK24).

Messier 87 (M87) is a supergiant elliptical galaxy with several trillion stars in the constellation Virgo. It is one of the most massive galaxies in the local universe, with a large population of globular clusters and an active supermassive black hole at its core whose mass is billions of times that of the Earth's Sun.

The black hole was (for the first time) imaged using data collected by the Event Horizon Telescope (EHT), with a final processed image released on 10 April 2019. In March 2021, the EHT Collaboration presented, for the first time, a polarized-based image of the black hole which may help better reveal the forces giving rise to quasars. See also:

A jet of of energetic plasma is emitted by the black hole and extends at least 1,500 parsecs (4,900 light-years), traveling at a relativistic speed.

The dataset consisted of 2 x 600s subs with each filter (LRGB). Image processed with AstroPixelProcessor and Photoshop CC (and some plug-ins).

In one of the subframes acquired with luminance filter, a glimpse of this jet could be recognized: see the more detailed images of the core of M87 (in the smaller frames)

Are there other observations of M87, with a more pronounced jet, available?
