Description

This is a very amazing sky area. This galaxy cluster contains more than 300 galaxies being a part of the Great Wall.

The data was gathered in three nights without real astronomical darkness. Most of the subs were taken at nautical twilight.

But the biggest problem was the tube seeing. The system heated up over day time and the difference to night was more than 25 degree. The system was in usable state after 0:30 o‘ clock, which reduced the remaining time even more.

Please enjoy!
