Have you wondered how to take your night and milky way photography to the next level? Are you tired of showing up to the shoot location unprepared? In this complete guide on night photography planning, you will learn my planning workflow and all of the free tools I use to plan and photograph my night and milky way photography.
If you’re the kind of person who learns best via video tutorial, I’ve covered my entire workflow and the free planning tools for night photography in this video then just hit the play button. Or, if you’d prefer to jump into the article, then just scroll right by.
When I first picked up night photography a few years ago, planning barely included filling up my car with gas. I’d simply drive away from the city in any direction, moon or no moon, and snap a photo. It didn’t take long before I became frustrated with this approach and I determined I needed to learn the tools that it takes to plan thoroughly for night photography and capturing the milky way. The other thing you need to know about me, I am cheap. So my planning workflow needed to include tools that were completely free for me to use. Before jumping into my workflow around the free tools available, I will say that I’ve heard a lot of good things about PhotoPills and have recently purchased and use Planit Pro: Photo Planner. Planit Pro has replaced a few of these apps and has some nice added features. So, if you’re willing to sacrifice a few cups of coffee for an app, then go ahead and buy one of those apps. They don’t entirely replace some of these and I still use this workflow, so keep reading for some tips and planning tools to supplement these robust apps
Before you can even decide where you want to go and what landscape you want in your foreground, you need to know what’s in the night sky. As the earth rotates throughout the year, different parts of the night sky become visible. Understanding where these sections or objects are in the night sky is a vital first step in planning for your landscape astrophotography. I recommend a desktop program called “Stellarium” to help you understand what is in the night sky and when it will be visible in your location. There is a handy date and time function along with a location function in the left-hand panel. This allows you to input your potential shooting coordinates, and run through an unlimited possibility of dates and times so you can see where objects line up at different points in the year. An easy example: the shiny milky way core in the northern hemisphere summer sky (pictured below). Stellarium will tell you it is above the southeast horizon in Regina, Saskatchewan beginning just before dawn in February and will set over the southwestern horizon in September.
If you’re after a free phone app, I use SkyView that is very powerful for a free app. It even includes an augmented reality feature that utilizes your phone’s camera to align your surroundings with different night sky objects such as the milky way. You also can change your location and date/time to view where different astronomical objects might be at a future time somewhere else to aid in your planning workflow.
So you’ve figured out what object or part of the night sky you want to photograph. Now we need to nail down a general location and time. Trying to photograph the milky way or faint nebulae will be very difficult if you are too close to light pollution, there is a bright moon shining in the sky, or the sun isn’t far enough below the horizon.
Light pollution is a brightening of the sky caused by street lights or other man-made sources. This brightening has a disruptive effect when viewing and photographing the night sky. This means you will need to get away from the lights of the city or town, keeping in mind the direction you want to face to capture the celestial object you had in mind (ex. heading south instead of north to capture the galactic core during summer in the northern hemisphere). I frequently use this Light Pollution Map on a desktop or “Light Pollution Map” app on mobile. The map is coloured coded so that the further you move away from red, yellow, and purple, the darker the night sky. I successfully photograph the night sky in darker green, blue or absolute dark skies. It bears mentioning that you need to keep the night sky object you want to photograph in mind. If you’re photographing the milky way, for example, you should try to move south of the light pollution.
The moon has the same effect on astronomical objects as light pollution does. The reflected light of a full moon washes out all but the brightest stars in the sky, making nebula and other night sky objects difficult to photograph. Ideally, you will want to photograph on a date when there is no moon present or a very small one (the photos below is of the milky way with a 78% illuminated moon rising, compared to truly dark skies). To find out the moon cycle for a potential date range, I use Time and Date to see when the moon rises and sets. This tells me when there is going to be no moon in the sky and gives me a better sense of what dates and times are possible for the photo that I want to get. If I’m on mobile I use an app called “Lunar Phase”.
The last factor to consider is when the sky will be darkest. Simply going out after sunset may not yield the darkest skies possible. There are different levels of twilight after sunset. First, we enter what is called Civic Twilight (we call this blue hour). After this, we experience Nautical Twilight and finally Astronomical Twilight. Dark skies occur when the sun is 18 degrees below the horizon, or after Astronomical Twilight. At this point, the sky is no longer illuminated by the sun and we have Astronomical Dark. I find the times for Astronomical Dark by using Time and Date if I’m on a desktop. If I’m using my cell phone, the “Light Pollution Map” app has an integrated countdown to Astronomical Darkness, and “Clear Outside” has listed Astronomical Darkness start and end times right in the app. Clear Outside also has a handy location feature that allows you to load any location in the world.
We now know what night sky object we want to photograph and where it is in the sky, we know when and where the sky will be darkest. Nailing down exactly where we want to shoot is the next step. This stage could (and will) come first in time. Once you begin to understand what night sky objects line up where and when you can begin to plan the locations you want to shoot FIRST, and then plan when you want to photograph them. Initially, it is helpful to get to know the night sky and understand when and where skies are darkest to give yourself the best opportunity to practice night photography.
Regardless if this happens first or last, there are two approaches I use to determine where I want to go. The first and most obvious is to visit the location in the daytime. Nothing can replace physically seeing the space and visually understanding how things are likely going to align. This is where an app like Planit or SkyView with an augmented reality feature comes in handy. You can pre-visualize where different night sky objects line up. If for some reason that is not possible or practical, I rely heavily on Google Earth. You can navigate to any location in the world and see locations from the comfort of your arm-chair. By using the street or ground view, you can put yourself into the environment you will be trying to photograph. This will help you to see which landscape objects will be roughly where before arriving at the shooting location. That said, I always recommend getting to a place early to explore the compositional opportunities in daylight. You don’t want to be left scrambling and hunting for a composition in the dark.
After this, I’ll jump back into Stellarium, enter my GPS co-ordinates, set my date and time, and the general direction of the shot based on what I’ve uncovered in the previous 3 points. Next, I need to set my field of view. In Stellarium, you simply zoom in and out to change your field of view. This will show you what different astronomical object will look like at various focal lengths. I use Chris Jones’ Calculator to find out what field of view I need to set for various focal lengths. There is much more to this point if you’re interested in getting into telephoto landscape astrophotography like what I’ve pictured below. If that’s the case, then be sure to check out the additional details in the video above.
Weather is a major factor when planning for night photography. You cannot photograph the milky way and other night sky objects if they are covered in clouds. I always start my planning workflow by nailing down a where, how, and a possible when. It is important to leave it as a possible when (unless there is only a day or two when things align, which does happen!) to leave some flexibility for the real possibility of being clouded out. I use Clear Outside and Windy (both of which have accompanying mobile apps) to understand what the weather holds and what the cloud situation will be as I get closer to my potential shoot dates. I pick a day when Clear Outside has forecasted less than 50% clouds coverage for that night and Windy is showing that the direction of the clouds (if they exist) is moving away from my spot. One bonus tip. You can photograph the stars, milky way or other astronomical objects with a layer of thin high altitude cloud. You won’t see the same level of detail in the night sky, but this kind of cloud adds a beautiful star glow effect that is normally only achieved with a filter. So don’t let this kind of cloud keep you in bed, get out and experiment!
That’s it! You are ready to head out and capture the night photograph you’ve always dreamed of.
