NGC 7000 LRGB

Very nice.  My only critique is that it looks like blacks are clipped.

Maybe you're right... Where can i check the blacks? In the histogram?

Yes, you need to stretch so that data is not clipped when looking at the histogram, usually you then see a sudden sharp cut-off on the left side instead of a nicer curve.

Damn... I' ve to take care of this in my next projects! Thanks for your feedback 🙂

Great image Gernot 😉 @skanker @vincent-mod @leuthold

Very nice. My only critique is that it looks like blacks are clipped.

Indeed, some of the blacks are clipped which you want to avoid.

Here is an example with and without Black Clipping, if you visually look at the image/data, sometimes it isn't that apparent, but the Histogram tells you what actually is happening, the Left Side of the Histogram needs to be near zero to prevent black-clipping anywhere in the image.

With Black Clipping, see left side of the Histogram:

Without Black CLipping, again, see left side of the Histogram:
