This didn't turn out as good as I was expecting, considering the time involved. The near 3/4 moon definitely didn't help. This is my first Ha, LRGB image and my second LRGB image

 

Ha : 60 minutes
L: 60 minutes
R: 90 minutes
G: 90 minutes
B: 60 minutes

 

Stellarvue SV80 Access
EQ6R-Pro
ZWO ASI183MM Pro (imaging camera)
ZWO ASI120MC (guider)

 

I think a larger aperture scope is in my future.

You don't need a bigger scope, just more time on target, especially the RGB if you're in a light polluted area. Your picture looks great, just a little noisy.

Did you try just a LRGB combination of this target? M101 has very low Ha signal aside from the nebula regions. Depending upon how you combined the Ha into the LRGB you may have transferred a good amount of noise from the Ha channel into the image.

 

Just a thought.
