Nice images. Definitely worth persisting with the cal frames though (flats, darks and biases). They will make a big difference when you get them right. For DSLR imaging I take my flats on a daytime sky and usually median combine 50-100 frames. I do darks and biases at night when the temperature is around the same as lights but again combine 50-100 frames to get the noise down.
BTW – Turn your scope on C/2014 Q2 (Lovejoy) and have a go at that.
