Abell 2151, the galaxy cluster in Hercules: a deep view

Abell 2151: a long exposure unveiling countless galaxies

Earlier this month, we managed to capture a sight of the Abell 2151 galaxy cluster in Hercules. That view was a very inspiring one and the resulting image was widely appreciated by our visitors. So, we decided to push our vision even further, adding more exposure time.

Below is a much more deep, smooth and rich image, coming from the average of 25, 360-seconds exposures, unguided, remotely collected with the  17″ main, robotic unit part of the Virtual Telescope. The image scale is 1.2″/pixel. This is one of the deepest images captured so far from our facility and it shows countless galaxies, many with amazing shapes, surfing space and time at half a billion of light years from us.
