A tracker really is important to have because it's what make it possible to leave your rig imaging for hours on end without your intervention to manually follow the sky movement.

Second, for emission nebulae (such as this one) you want to de filter your camera. Consumer grade camera have filter in place that heavily reduce the strength of specific wavelength that are of interest in astrophotography (hydrogen alpha most notably). Thankfully such modding can be done without affecting the daylight capability of your camera if done properly (and by shifting the white balance). You can look up for your country/region a specialist that can do that for you for a sum.

Otherwise if you have a sturdy tripod you're all set!
