Hi Andres, nice photo. Why you have such big halos on stars? What narrowband filter you use?
Also check Gain for your 585 camera. With filters and latest firmware from ZWO it definitely will be better to use gain 200 with narrowband filters. Check zwo website and page about asi585mc pro with graphs for DR. Using gain 120 is wrong scenario. If you want to shot in LCG use gain around 50. Otherwise 200 will be best chose.
