Just got a break in the clouds and was interested to see how much difference the Moon made - fortunately not as much as I thought that it might.
The target (occultation) star is the brighter one almost dead centre (slightly below) of the image, and Pluto is the first object out at 5 o'clock (approx 25% of distance to edge of frame in 5 o'clock direction).
Exposure: 1.6 seconds
Other data from plate solve:

Let's hope for clear skies Tuesday morning!
