That is very nice.

Ha  with 120s subs ... a few years ago that would have been a joke. Another great demonstration of what these CMOS cameras can do.

But you've made the most of it = very nice image of M81.

As a matter of interest, as I have the same camera, what were your Gain / Offset settings?

It was all done at unity gain. But next target the rgb will be done at gain 76 to get less saturated stars.

This time a rework in Pixinsight.

I hope I did not overprocess in pix.

Very nice image, crisp but just on the right side of overdone!

What gain settings do you use and what's your sky like?

I'm just getting started with the same camera, so it would be useful info.

Thanks

John

This one was done at unity gain. My sky is fine for a belgian one. But m81 is high in the sky what makes a huge difference
