I managed 2 comets last night: C/2009 P1 Garradd AND 78P Gehrels. The latter is much harder to see but here’s the result using Canon EOS 5DMkII at orime focus of 254mm f/4.8 (f=1200mm) Newtonian: 
78P is in Pisces, directly under the square of Pegasus, so not very high up. I you want to know where exactly to find it use the Computing Section’s applet: http://britastro.org/computing/applets_planets.html Add the object, click on it to see details, click the button for drawing a chart.
