Moonrise, Lincoln Memorial
Photographing the moon, stars, and the Milky Way brings a different set of challenges, most often in planning where to be and when. Happily, this is no longer as hard as it used to be, because there are various apps such as The Photographer’s Ephemeris (TPE) or PhotoPils that enable you to predict where the moon and other astronomical bodies will be at any given time and location.
The picture above was taken in 2001 when such things did not exist. You needed a compass and a chart with the azimuth of the moonrise. On March 9th, the moonrise was at 6:19 PM, 10 minutes after sunset.
Moonrise over Washington DC
(Tech: Nikon D200 with 18-200mm f/3.5-5.6 lens, @ 200mm, exp: 1.8 sec. @ f/5.6, ISO 200; 3 vertical images, photomerged)
Capturing a full moon rising over Washington, DC from this location near the Netherlands Carillon is a much desired goal of many local photographers. These days, when the alignment is expected to be good, you will find as many as 100 photographers at this location poised for the opportunity.
The image above, however, was photographed on Sept 5, 2009, the night after the full moon, and also back before TPE and other apps were generally available. There were less than a half dozen photographers up there that night. The next chance for an almost identical shot at this location will be on October 5, 2019.
Iwo Jima and Crescent Moon
The moon doesn’t necessarily have to be full to find an interesting angle, but it might mean that you have to get up early in the morning. This was taken at about 5:20 AM, during civil twilight when the waning moon was about 19% full.

Lunar Eclipse Multiple Exposure
(Tech: October 8, 2014, Total of 18 Exposures over a 64 minute period, exposures varied depending on brightness of moon)
A lunar eclipse is a relatively rare event, but it can be photographed in a variety of ways depending on the timing and track of the moon across the sky. In this case of an early morning eclipse, I tried an application of the stacking technique I learned in a Michael Frye workshop for shooting star trails (discussed below). The next total eclipse in Washington, DC will be on the night of 20-21 January 2019. Information of the date and locations of upcoming eclipses anywhere can be found here.
Milky Way over Gaylor Lake, Yosemite National Park
When photographing Stars, one has to get away from the light pollution of city lights. Dark skies, such as Yosemite National Park, are increasingly rare. One place to find them is at the Dark Sky Association website.
This kind of photography involves a number of considerations. According to Michael Frye: “Capturing pinpoint stars requires relatively short exposures, otherwise the stars become streaks instead of points. You can get away with exposure times as long as 30 seconds with wide-angle lenses. To gather enough light to show faint stars and the Milky Way with such short exposures, you need both a wide aperture and a high ISO. The wider the aperture and the higher the ISO, the more stars will appear in your photograph. But you might not want to use the widest aperture on your lens, because all lenses are sharper when stopped down a bit. Or if you have something in the foreground you may need to stop down slightly to get sufficient depth of field. To start with, try 15 to 30 seconds at f/2.8, with the ISO at 6400. If that doesn’t show enough stars, try a wider aperture or higher ISO.”
The Milky Way is not visible in the Northern Hemisphere during January and February. For a comprehensive discussion of when and where to photograph it, check this link.
Star Trails, Sonora Pass, California
The technique for capturing star trails is similar to shooting the Milky Way in that a fast (f/2.8 or better) wide angle lens (24 mm or wider)are necessary. But instead of one relatively short exposure, this kind of image requires a series of long exposures at a relatively low ISO. The above image involved 30 separate exposures, each four minutes long with a 1 second interval between each one. The aperure was f/5.6 and the ISO was 400. An intervalometer was attached to the camera to manage the sequence of shots.
Then, during postprocessing, you can load all the images into photoshop as layers. You then click off the visibility (the little eyeball on the left of each layer) of all layers except the bottom layer. Then Cchange the blend mode on all layers to “lighten” and the star trails will appear. This action blends the layers together keeping only the lightest areas of the photo. Merge the image as a single layer.
I hope these three posts on low light photography are of some use to readers interested in taking on the low light challenge. For now, however, I will be taking a break from my blog for about 6 weeks as I get ready for an upcoming trip to the monarch butterfly preserves in the Sierra Madre Montains of central Mexico. You can get an advanced peek at what I hope to see there by checking out my post from 2016.
