The earth rotates permanently under the starry sky, therefore our recordings must not take too long, otherwise the stars will no longer be recorded as points, but as lines. Number of frames, shots, interval and duration You shoot in JPEG? Please find another hobby. With the right white balance, the depths of the Milky Way reveal themselves particularly impressively. Therefore manual white balance to relatively balanced color temperature. It is important that the white balance is not switched back and forth by the camera by an automatic during the shooting. I make the adjustment later in post-processing. I use the white balance for the cloudy sky. To do this, we use Live View, then zoom in on one of the brightest and most central stars in the frame and focus on it manually. Of course, this is at the expense of the exposure time. In special situations, for example when the landscape in the corners of the image is to be made even sharper, it makes sense to reduce the aperture by one or two stops. So open the aperture as much as possible. Since we want to let in as much light as possible, as described before, it only makes sense to work with these fast lenses with almost open aperture. On my full frame Nikon Z6II * I use the Nikon Nikkor Z 20mm 1.8 *.īoth lenses are wide-angle lenses due to the focal length, which are able to capture a large part of the sky and/or the surroundings with their field of view. My favorite lens on the DX (APS-C) camera has always been the Sigma 18-35mm 1.8 Art *. Using the right lensįor astrophotography we use very fast lenses, which let in as much light as possible with the largest possible aperture. Shooting timelapse scenes becomes even more complex when you are shooting them within changing lighting, for example from nighttime into the daylight, because you would maybe have to change settings during the shooting to prevent the image from over- or underlighting. You will need a setup timer that helps you to trigger the camera in special intervals. Photographing the night sky with one shot is easy: Setup, point, shoot, optimize settings, repeat until the result fits your expectations.ĭoing timelapse movies is more difficult, and doesn‘t set you free from the steps before. Rather, it is a guide for the basic setting of your setup, from which you can then adjust your equipment so that you get good pictures. This article is therefore not a patent remedy for successful photos. How much noise an image has at which settings or how much light enters the lens in which time is always strongly dependent on the hardware used. This is photography in general, but nowhere is it as obvious as in astrophotography. A high ISO value ensures that we have to expose for a shorter time, while at the same time a higher ISO value ensures higher image noise.īasically, you can say that astrophotography is the constant search and optimization of compromises. To make this work, we can make things easier with the ISO setting. The trick is to set the camera so that we capture as much light as possible in under 25 seconds. The problem is that we cannot expose infinitely long, because then the stars would no longer appear as points but as lines, after all they are “moving” all the time.ĭue to the Earth’s rotation, it can be said that all images of stars appear as a line when the exposure lasts longer than 25 seconds. Thus, we have to expose for a very long time. When photographing stars or the Milky Way, we have very little light available. This post was originally my own note for photographs of stars or the Milky Way. Waiting for a timelapse to finish is a great time to think about the next composition.In this post I write about my basic settings and procedures for astrophotography and creating timelapse scenes. I’ll sometimes shoot 4+ different angles in a night. Shooting meteor showers, comets, conjunctions, and eclipses require extensive planning to get images, but you’ve got to be ready for spontaneity when in the field shooting. The timescale of these terrestrial subjects are far greater than our perception, similar to the life cycle of a star.īut following along celestial events have guided a lot of my work. Ocean, desert, and mountains are my favorite landscapes to juxtapose with the sky. A dark sky is a must (new moons are always a great time to shoot astro), and then comes the landscape. There’s still a lot of shots I have in my head before I get to a location, and a lot of conditions to think about before I show up. JH: Planning is what keeps me sane during the day time, but every timelapse is a trial and error in my opinion because you never know what’s going to happen when you start the camera. KU: So how much thinking ahead are you doing?
