Description

This is the Galaxy cluster Abell 2218.
The Hubble telescope took in 1999 a very spectacular image of the cluster and it gravitational lenses.
I shot this image in the hope to capture some very dim gravitational lenses, at least recognisable artifacts .
But as you can see there is absolutely nothing what looks like a gravitational lens. Obviously the 10" newtonian is way to small for this job .
