There were quite a bit of clouds early in the evening, but it finally cleared up a bit on the horizon ... although still quite hazy. Then the wind picked up, so even after moving the car and positioning the tripod right next to it (with the door/window open so it was "tucked in") as a wind-break, there was still a ton of wind-inducted motion, even with the lens hood removed - image was bouncing all over the place using Live-View at x5/x10
I had staked out a spot based on the Photographer's Ephemeris which was dead on with the compass heading of the moonrise. But the vertical angle wasn't good for the Rocky Mountain Airport control tower ... so I moved to a lower position slightly to the South that was lined up with some remote water towers. I figured since the shooting conditions were so poor, I might as well get "that" and then consider a composite shot. And in hindsight, shooting the night before would have been even better as the sun would not have set yet and light would have been nicer on the landscape.
So I'm watching the horizon for the 7:56 moonrise ... and literally didn't even seen the moon until it had almost cleared the horizon - it was that hazy. I had originally planned to shoot at F/8, 1/500s, ISO200 using the "Moony F-11 rule" plus some test shots a previous night ... but that wasn't even close. Because of all the wind, I just gave up trying to get a sharp shot of the moon with a higher shutter speed, so ended up using F/5.6, 1/20s, ISO400.
The moon disappeared into gathering clouds about 15 minutes after coming up and as I drove off, quite a bit of lightning lit up the sky to the East. At 9:30PM that night, we were driving Eastbound from Boulder and pulled over at the Legion Hill lookout to watch the spectacular lightning (bolts and sheets through the clouds) over Denver.
In order to get similar relative size, you need to know the ratio of the Moon's distance to its diameter ... which is pretty close to 100-1. Incidentally, the ratio of the Sun's distance/diameter is also about a 100-1 ... which is why a Solar eclipse "fits" just right. So running a 294.1° radial from the Control Tower, there was a spot where I could park 7,000 feet away (reachable with the car) so 70' at the Control Tower would be about the same "size" as the moon. Fortunately, that spot had an unobstructed view, but the vertical angle was a bit too high - and then it was very windy/hazy - math can't do it all for you! ;-)
Another "real world challenge" was that my primary idea was to try shooting the NREL windmills and I had a cool spot picked out party way up Fowler Road from Eldorado Canyon - the windmills are HUGE (but I had the right distance ratio) and probably would have been right on the horizon. But halfway up that road, there was a locked gate ... and I didn't want to hike with all my camera gear a mile up the road - D'OH! ;-)
