You can do it. However, you will lose some resolution. For example, the pixels under the red Bayer matrix filters will be the only ones to record anything from your H alpha filter. So you'll be using only a quarter of the pixels of your sensor when you take an Ha shot, a quarter for an SII shot and a half for an OIII shot. Still, I've seen some good stuff from patient people using narrowband with a OSC camera.

Do a google on "narrowband with OSC".  Should turn up a lot, for example
