Milky Way or the Orion constellation, getting the perfect focus on your lens is crucial. Focusing a camera lens during the day is completely different than focusing at night. In this tutorial, we will show you how quick and easy it is to achieve the perfect focus with any DSLR camera or lens. Before even looking up to the stars, we need to make sure the settings on your camera are correct and will make the task easier. We suggest being in Manual or Bulb mode since you will likely be imaging after that but, as you can see on our image below, we were in AV mode that night and it did not make a difference. Bulb mode when you are ready to image. Have this wide open, so the lowest possible number your lens will allow. This will help your sensor gather more light and so you will have not problem seeing the stars. Astrophotography at different apertures. We usually do 800 or 1600 by habit, and sometimes lower it down when we are ready to image. Before actually going outside and point your camera up, ensure that the lens you are using is set to Manual. When it gets dark enough outside, look around and try to spot one of the brightest stars. We usually aim for Vega during the Summer, and Rigel during the Winter. Planets are very bright and might also work, but those are so bright that depending on your lens, they might actually make your job more difficult. Sirius is also very bright and some people might argue that it is too bright to be used as a reference star for focusing. We would agree if focusing with a telescope, but if you are just using a lens on a camera body, Sirius is fine in our opinion. After picking a star, aim your camera at it, at least in that general direction. On your screen, see if you can spot the star or if you need to move the camera around a little bit. If you still cannot find it, start to randomly play with the focus ring on your lens. As you can see on our image below, our star is clearly out of focus. All you need to do now is to actually focus. The goal is for the star to be as small as possible when looking at it through Live View. Turn the focus ring on your lens until the star starts to shrink. Once you achieve perfect focus, make sure you do not touch the lens during the remaining of the night. If you plan on using this lens solely for Astrophotography, it is a great idea to carefully tape the focus ring to the body of the lens after achieving focus. That way, you will not have to repeat the process again anytime you image! We personally never used this trick as we also use our lenses to record our videos. Some lenses have an infinity sign on them, which tells you exactly where to stop the focus ring to achieve perfect focus on the farthest possible object. We suggest not using that feature but rather check for yourself in the Live View because it might not be accurate enough for stars. We have dozens of tutorials that range from equipment suggestions, acquisition tips and processing techniques. Best affordable DSLR camera lenses for the Milky Way!
