X Marks The Spot
New tools to guide you to the perfect place for the perfect photograph
Bingo! At the moment of sunrise, the moon will be directly over the saddle between Longs Peak and nearby Mount Meeker—close enough to Longs that you can use a telephoto lens to magnify the moon, yet still have Longs and Meeker in the frame.
But wait—you have to check one more thing. Drop the Secondary Marker where the black line indicating moon direction crosses the saddle between Longs and Meeker. In the info panel, you can see that the altitude of that saddle, measured from the summit of Twin Sisters, is 4.3 degrees. Now look at the altitude of the moon at sunrise—6.7 degrees. Perfect! The moon will be 2.4 degrees above the saddle at the moment of sunrise. Since the moon subtends an angle of 0.5 degrees, that means it will be five moon diameters above the horizon at sunrise. If the sky is clear to the east at sunrise, you should be able to make a strong “triangular” composition with three main points of interest: the moon, the summit of Longs and the summit of Meeker. Add some warm sunrise light on the peaks, and you have a winner. Checking the other four dates provided by Heavenly-Opportunity shows March 21 to be the best day in 2011 for shooting moonset over Longs Peak.
