Even when you add a focuser, a rotator and dew control you would almost have enough change left over for an sbig stt3200 with self guided filter wheel and ao8t..If you want to hunt dim galaxies you would be hard pressed to go past the 3200me sensor. 6.8um pixels, 85% QE and huge maximum well depth.
At the fl you plan on imaging I would strongly recommend ao. Even at only 1000mm I find the difference is quite noticeable.
