Great image - I like the composition with the inclusion of the more distant galaxy on the right.  Very nice star colours too.

Thanks for you answer !!!!   As I said, I´m new with this camera and I haven´t use it because of the weather.  I´m planning to use Sequence Generator Pro, 3 and 5 min lights.   In the new ASCOM driver from ZWO Unity Gain settings are Gain 90, Offset 65.  In your opinion/experience are suitable for DSO?  Why did you choose Gain 0, Offset 10?    Sorry to ask but I´ve been searching all over the web/forums and haven´t found information.

I live in dark area so I can get maximum dynamic range but the trade off is higher read noise. But as for a starting point. Unity gain is fine, but it comes down to how close you live to a city or town. If you live to close your images will be washed out at 5min lights.  Have a look at this. https://www.cloudynights.com/topic/590093-suggested-sub-exposure-tables-for-asi071mc-c-and-qhy168c/
