For reference, here's my first attempt at M101 with exactly the same hardware (and twice as much scope time).

Between my first and latest attempt I adopted/learned about:

• BlurX, NoiseX, and StarX
• Binning
• Drizzling
• Sensor gain
• Background extraction in PI
• Dark Flats
• Various other PI things

Don't let the limitations of your hardware stop you. There's always something more to learn.
