Dark adaption is something you really have to be aware of. If you go straight outside from a brightly light room you will be lucky to see any but the brightest stars. Wait 5 minutes and the Milky Way pops into view, want another 10 mins and the Milky Way shows a lot of structure and lots more stars are visible. At that stage I know I am getting close enough to dark adaption to observe.
If like me, your observing site has a bit of ambient light that is probably as good as it gets but at a dark site the eyes keep getting better for up to an hour.
Using a computer, ipad, iphone is really bad, they are very bright so get some charts or print them of from your computer (laminate them if possible to protect from dew) and a DIM red light and you will start to find more stuff.
In Sag you have M8 (Lagoon Neb), M17 (Omega Neb)M20 (Trifid Neb) M21 (Open Cluster) M22 (Showpiece globular) M55 (Glob) and in Scorpius you have M4 (A looser glob) M6 & 7 (Open Clusters). All easy to find and some are vis to the naked eye! (M8 and M7 particularly)
