There are a lot of them, and coverage of them is obviously linked to rise and set times. For example, Eta Carinae is currently rising high enough to image around 3am, which only gives you a limited amount of time until astro dawn begins around 4am. So pick your targets based on your preferred imaging time. I would suggest using your planetarium software to browse what is available above 40 degrees in the east, as this is high enough to minimise atmospherics, and there will be plenty of time to image as they rise and transit.
Also, start with the brighter ones, you get a good return on your narrowband investment, and it allows you to work out your sub exposures. Faint objects, like say the Vela SNR, can require more sub numbers or total data time duration. Have fun, i find narrowband very rewarding, preferring it now to LRGB.
