Description

Red x 22 Blue x 22 Green x 23 @300s

The Grus-Quartet consists of four large spiral galaxies which are so close to each other that they should be interacting. The high starburst activity of two of the members, namely NGC 7552 and NGC 7582, is also thought to arise from tidal galaxy-galaxy interactions and subsequent formation of a bar in the disk.

My last RGB object(s) before it got just too hot leave my gear melting under an Australian Summer.

It's going to hit 50 in there today so I think I will have to rescue my EcoWitt WiFi sensor too.
