OK I know I ALWAYS say this but these are really really quick snaps - usualy to take any deep sky pics would take about 1/2 an hour to a hour to setup followed by several timed shots stacked and processed - now these are really not great but it does give you some idea of what is possible
I went out with the tripod and polar aligned which took about 2 minutes
pointed the camera on top at the 3 stars in the middle of orion and opened the shutter for 2 minutes
now the one I took the other day showed star trailing at 3 seconds and this was 2 minutes so the trac works perfectly! nice round stars - the trails on the left are down to lens problems
this is the 50mm 1.8

the orion nebula is over exposed - the horsehead and flame is visible on the left star of the belt - also there is a feint red band to the far left going up called Barnards loop not had that before
Hardest part was focussing which is very hard with a fiddly focus ring
Ok 1 shot was all I had time for as storytime beckoned so I put on the 100-400mm zoom and pointed it at the same area 2 minute shot this time and more detail
I KNOW this can do so so much more but Keith this is probably the answer you are looking for to take shots of nebulas and galaxies with the stuff you already have - the biggest challenge is focussing - in reality I would have taken 30 - 40 identical frames stacked them and subtracted dark and flats as usual but wanted you to see some 'hot off the camera pics'

Again orion, running man , flame and horsehead all in 1 shot
easy
and I mean easy!
