There is a lot of good open source work being done on the acquisition end of the hobby. Check out Ekos, INDI, KStars, etc. All these projects are working together and have the potential to replace their closed source alternatives. If you aren't running Linux there are some free ways to run all this stuff on a free virutal machine on you Windows or Mac machine.

quale regione? ;)
> So, getting to the point: some advice
what do you need help with? just with what you can see?
if you look south there are lots of galaxies and globular clusters in rich constellations.
Sombrero galaxy between virgo and corvus, M5 between virgo and serpens caput, M12 in ophiuchus (south-south-east) back to Virgo there's m61, m90 m86 m10 then m53 in coma berenicae napoleon's hat (nice asterism) just a little bit south west of Arcturus pretty much at the zenith there's m94 in canes venatici, m51, m101 in ursa major m106 nearby, m81 and to the west there's leo with his triple-galaxy group cancer due west etc
get a planetarium software like Kstars and configure it for your time/location/type of sky
There's this: https://heasarc.gsfc.nasa.gov/docs/software/ftools/fitsverify/
You might open it in Kstars, I think it's the nicest I've seen for editing fits headers, and see what it thinks. https://edu.kde.org/kstars/#download
If you've got the whole console output, that might be helpful, as there are error codes, that are usually adhered to.
The newest release of KStars/Ekos (2.7.8) on Mac OS supports all ZWO cameras. It is open-source, bleeding-edge software, so may have bugs, but it also offers a lot of nice features if you get it all working. And the best part is it's free with an active community.
