Thanks for selling me the filters Elliot. The OTA if I understand is the 150mm F5 reflector from celestron which weighs 12lbs and has a 750mm FL. The cheapest mount that you can use for that OTA I think is the CG5, you can find great deals on them as it's been replaced by the improved VX. The next step up would be the afore mentioned VX or the ZEQ25 from Ioptron but those will cost you about twice as much. You will be much better off buying a CG5 and getting a cheap autoguide package like the orion mini guide scope and old meade dsi with it than an unguided ZEQ25 or celestron VX. The next items I would consider on the shopping list to image in a light polluted area ( I assume you are in one since you had bought the narrowband filters) would be a CLS clip filter and a coma corrector. Fast Newtonian exhibit a lot of coma off axis and a DSLR as a large sensor.
