Description

The luminance of the brighter areas of this image, correspond to 3.5 hours of data acquired last week from my suburban backyard observatory, using a 6.6-inch apo refractor and a QHY600 camera. The color and general dark background belongs to a dataset of mine from 2013 (different setup, and better skies). Although the seeing was not particularly good, the overall resolution improved quite a bit, compared to the old image (http://www.pampaskies.com/gallery3/Deep-Space-Objects/Grus_Quartet). Also of note, is the amount of galaxies that are discernible in the background.
