NGC55 LRGB Ha O3 - Final Ver01

I found this difficult to get right, going around in circles.

One advantage is having lots of good data, which I do (25 hrs).

You might say it's been clipped, well it has.

'Soft stretching' I think, reveals the most detail and colour.

Could have made it really bright, but then you end up with the galaxy obscured in hazy noise.

I tried a 'new' technique such that there was no need to use 'Curves Transform'.

By playing with the 'Histogram Transformation' for each channel, then combining and repeating the process
until the colour was 'normal'.

A few masking artefacts but have to move on (making cheese).

All good fun and comments greatly appreciated.
