This image is of the Hydra cluster and centred on NGC3312 and NGC3314. NGC3312 appears as an almost edge on spiral galaxy and NGC3314 is two overlapping galaxies spaced at 117 million and 140 million light years. It is just purely a coincidence that these two galaxies line up to our line of sight. There are also a few giant elliptical galaxies in the field.
I am still trying to hunt down the star shape problem and have seen some improvement with the installation of a counter weight on the secondary assembly. So some of the star shapes are ok and some are a little egg shaped.
The image is an integration of 14 hours with 10 hours of it being luminance.
