Description

I really like the galaxy clusters.  Can you believe that the light sent from Abell 2151 (Hercules Galaxy Cluster) left when the first multicelluar life in acient oceans evolved ("the Cambrium explostion" it is called) 500 million years ago?  Althoug the exporsure time in this image is short, it is still full of tiny galaxies.

The image is also in a way "first light" with my EDGE 9,25 Hyperstar in a combinition with RASA8.  I try to figure out which of the two set ups give the sharpest image and so far I favor the RASA, but testing is far from finished. How lucky we are to be able to explore the univers with "simple" equipment

I fint the inverted version easier to study than the non-inverted one and took the chance to make a combo with both versions....

Enjoy... like always comments are most welcome.
