With that telescope have a look at the craters and mountains along the lunar terminator (a couple of days leading up to first or following last quarter are the best times - enhances surface features with reduced glare).
See if you can spot Saturn's rings (was better last summer but still viewable now before it is lost in the sunset twilight but will be at opposition again, ie closest and thus largest and brightest, in mid-August; ring angle is slowly closing as we head towards 2025). Look for the moons of Jupiter (at opposition late September is the best time but can be seen any time). Mars will be a better target in December when at opposition (in very good viewing conditions you might start to see hints of surface features).
Otherwise some classic double star pairs:
Albireo (best visibility in summer),
Almach (actually a quadruple star system) and
24 Comae Berenices (actually a triple star system) are striking colour pairings (gold/blue, gold/green, orange/blue), plus
Castor a blue/white pair (actually 6 stars orbiting each other but you'll only make out the brightest pair).
The open star cluster M45,
The Pleiades, always a pleaser and try the Great Globular Cluster (tightly packed old stars)
M13 in Hercules.
You could try the
Orion Nebula (M42) too but nebulae and deep sky objects really need a dark sky location to view them from (and a larger telescope to collect more light). Obviously the darker sky observing location you can find, the better (near coasts away from major population centres, around/near national parks, etc).
