For September, there's a lot of stuff in the milky way band still. Although I guess we've covered those before? M8, M20, M16, M17, M7, M6, Prawn, Lobster, Cat's paw.
Don't forget the often ignored Pavo globular cluster NGC6752. Often overlooked but third in line after Omega C and Tuc47. Speaking of which, Tuc 47 super globular is coming up along with the SMC.
Grab NGC253 The Silver Dollar galaxy if you haven't already along with the Helix nebula NGC7293. If you want a challenge, there's a few galaxies rising in the east to pick off. The Grus quartet is nicely place now, NGC247 another large but fainter galaxy near NGC253. NGC300 is a big faint beauty. Needs lots of time though. NGC55 string of pearls is a nice big edge on galaxy. Go on, go out of your comfort zone.
For a challenge try the Saturn nebula! Cool visual target but hard to image!
Over to the north there is the veil or witch broom nebula, if you can see low enough.
