You should be able to bring them out with simple 3 minute exposures. I exposed for 5 minutes with these, but 3 minutes is more than enough on Orion. Or you can be adventurous and try a whole bunch of different exposures targeting different parts each time (outer dust, inner dust, core, etc). For me the goal was to expose that outer dust whilst still showing (faintly) the trapezium in the middle.
Then stack your frames and calibrations to get your master image. Take that into your software of choice. In Photoshop, do very gentle level adjustments. Small bits at a time, but several in a row keeping an eye on the black point. In PixInsight, the STF will show you easily, and then when you do your final stretch, just watch your target mean. With Orion you need to find that balance between the dusty lanes and the bright core.
Orion is really a target for both beginners and experienced photographers; it's got something for everyone, and it's still teaching me a lot!

Thanks - some good tips there.
