Observations are described for the NORTHERN hemisphere and can be made by naked eye, small binoculars or by small telescope..
Mercury reaches the greatest west elongation (18 degrees from the Sun) on September 12. This means that it is west from the Sun, hence observable in the early morning twilight. Mercury meets the Moon on September 19/20 (i.e. the night from Sept. 19 to Sept. 20); the Moon will be south from Mercury and very close to the planet.
This planet can be observed in the early morning as a very bright object over the eastern horizon. The Moon will be very close to Venus on September 17/18.
This planet is observable in the evening around 9:00 p.m. local time in the southern sky, quite low over horizon. You can see it by naked eye, but it is necessary to know its actual position among the stars. Using binoculars, you can see its yellow disk. To see its beautiful rings, you will need a small telescope with, say, 60 mm objective lens, the magnification around 70x and a sturdy tripod. The rings are wide open and we see them from the northern side.
