Mike reports that with the recent news about the amazing image and subsequent science data from the super massive black hole in M87 galaxy taken with the Event Horizon Telescope he remembered imaging M87 in the past and so looked back in his records (as did your gallery editor!).

Like me, Mike was impressed by what can be achieved using a relatively small telescope from your back garden!

He took three 90 second images with no filter and calibrated them (light plus dark frames). The three images were then combined in CCDSoft and a DDP filter applied.

One can see the forward facing relativistic jet which extends some 5,000 light years.  The M87 galaxy is truly enormous and dwarfs our Milky Way galaxy.  It is classed as a supergiant elliptical galaxy located from our vantage point in the constellation of Virgo some 55 million light years distant.
