Ed,
Your right, the pump is a little noisy, and it vibrates a little. My intention was to only run the pump for 15 mins or so prior to observing whilst I also had the cooling fan blowing onto the primary and up the tube. I think in conjunction with the fan I will only have to "stir the air" above the mirror for a short period to get rid of the boundary layer and tube currents. I have mounted the pump firmly to the side of the rocker box so vibration and noise should be dampened a little by this.
