Hello,
1h 7mn total exposure with small 6-inch newtonian. 135 x 30-s frames, gain 300, RAW16, 14 bits, sensor temp +5°C (the air was very humid), no flat (too lazy), no dark nor offset (useless with the noiseless camera).
Noticeable light pollution, the Milky Way was totally unvisible.
Some faint stars were not perfectly aligned though; I presume I've set a too high value for threshold level detection of stars in DeepSkyStacker.
Note some faint, spiral galaxies in the large image field.
The camera is much more easy to use and performing than a DSLR !
Nicolas.

Very nice shot! light pollution need using a filter. I recommand MDL for align and stack images. DSS is too old, and always can not get best result.

Thank you Sean,

I've just ordered a 2-in UHC filter.

Is there any more modern, free option for DSS?

Hi NDB!

Very nice shot. I have the same camera and not happy with the lack of colors in my images, mainly the red.
Your image appears to have the same "problem". Why trere are no colors in that image?

stumbled across this, hope you don't mind a revised edit - there is a green bias in your cluster and the black point needed to be better balanced.

personally i think it's a great shot - these kinds of images don't have a lot of color but i can see the differences in stars within the cluster.

Just updated with a few curve adjustments in photoshop
