Lift off

So Im planning to get more advanced in astrophotography, and therefore switching from some quite beginner freindly equipment to some more technical. What I had in mind was "just" to shoot some narrowband nebulae and maybe a few galaxies. My setup I had mind is following: WO gt71 triplet ZWO ASI183mm pro HEQ5 rowan belt mod Orion 60mm guide scope ZWO ASI120mm guide camera (Maybe a filterwheel, otherwise I'll just use a filter drawer) Do you skilled astrophotographers think Im on the right track- if not, I would like some help.
