Sounds like a case of bad seeing. The 8mm+2x combo gives you 374x so it's on the high side. With the seeing lately, mush is the best we can hope for

The one time I exceeded 300x this summer was back in Nov, I was getting a nice hard edged Uranus at 534x albeit with regular smearing as the seeing worked its magic, but at 381x it was a textbook sharp ball. Stars themselves were nice points at over 400x. On a typical night, attempting 500x + on Uranus gives me a nice blurry planetary nebula type thing.
