Nice Images Ron but way over processed.

Background is too black.

If you keep the back ground lighter when you process you will get a lot more detail in the Galaxies.

Ron have a look at Chris's Starry skies over Cranfleet Cut, Sawley.

Look at the sky you will see there is not a single black pixel in sight.

I've no idea how Pixinsight, PS or other software works since I use IRIS. In that, black is 0,0,0. Whenever I create a JPG using it, the black level is always set  quite a bit less than zero.

Black is always at 0 but the sky colour is way above that point.

You can move the lowest signals up away from zero using curves and levels.

Possibly unlike other software (?), IRIS is quite happy with negative numbers so setting the black level as a negative number is effectively the same a adding a positive offset.

Right I've re-processed them both as per Grahams remarks, thanks Graham constructive criticism is always welcome. (How would we ever learn??)

Thats interesting.

With the likes of PS and pixinsight  0 is in the bottom corner of the window so you cannot go to a negative position.

I didn't mean the X - Y position, 0,0 is the bottom left hand corner and you can't go negative. I was referring to the RGB intensty levels which in IRIS can be between -32768 and +32767 (rather than than 0 to +65535).
