Description

Been a while since I have looked at any galaxies so may return to this.

There was IFN in there but decided to keep it subtle rather than over stretch but may yet change my mind on this

Rev B - Little More IFN and worked details back into galaxies - must have included in a NR process last night - my bad!

Rev C - Decided i prefer with IFN pushed less as this allows more detail through in the galaxies - at least to my perception.
