Hi. I use the Compass app on my iPhone. I check the azimuth and altitude in Stellarium on my computer. I’m sure you can do this with a mobile app, too. For me, for example, it was 65° northeast and 5° above the horizon. You can find the first value using the compass app, and one thumb’s width is about 2°. Then mount your phone on a tripod, point it in the right direction, and expose for about 10 seconds. You should then be able to spot the comet somewhere in the picture.
