Some practical tips on finding Comet 9P/Tempel 1 -

At dusk, on any basic star chart find the line between alpha Virgo
(Spica) and gamma Virgo. Currently Jupiter is just southwest of gamma
Virgo. Mid-way between gamma Virgo-Jupiter and Spica is theta Virgo
(v4.4).

Your first finder line is between Spica and theta Virgo.

Next, using binoculars or your finder scope establish a second finder
line. The second finder line is about 5 degrees north of your first
reference line, and is line defined by 82 Virgo (v5.0), 74 Virgo
(v4.7), 72 Virgo (v6.1), 66 Virgo (v5.8) and 65 Virgo (v5.8).

Comet 9P/Tempel 1 is between these two reference lines. See the
reference charts listed above for the position on any given night.
