    The tracker doesn’t take the images. The user sets it up on their tripod, aligns it to Polaris (if in the Northern Hemisphere), selects the right motion mode (sun, moon, 1/2, etc.), then it’ll just rotate whichever body is mounted on it. I’m guessing OP used a remote shutter with a timer.

    Turn it 90 degrees and you have a badass peacock.

    [–] Blue Hour in the Italian Dolomites [OC][1315x1080] alexspaethphoto 1 points ago in EarthPorn

    Yup! Blue hour often contains many colors and tones. That's why it's one of my favorite times of the day to shoot.

    While hiking the Alta Via 1 this past July, I learned that it was always worth it to wake up for sunrise. Although Italy in general is a beautiful place, hiking through the Dolomites presented some of the most fascinating landscapes I've ever seen!

    This was taken on the morning of day 3 near Rifugio Lagazoui before heading in the direction of Cinque Torri. You can see more images from Italy and my other adventures on Instagram @alexspaeth.

    This photo was taken on New Year's Day morning from our camp near Glacier Point and is the first image from this timelapse. Talk about a great way to start 2018!

    Exif: Sony a7 24-240mm at 24mm f/9 ISO 100 8s.

    Is this Bartlett Cove from Glacier Bay National Park? If so, I'm guessing you're a ranger there. I was just there in May for a kayaking trip up the West Arm and it was awesome!

    [–] The Milky Way graces the sky over Mt. St. Helens on a clear summer night [OC][2000x1346] alexspaethphoto 1 points ago in EarthPorn

    Sure. So imagine you're driving on a highway and looking out the window. The trees and telephone poles closest to you are whizzing by, while the mountain range 50 miles away is only slowly going in the opposite direction. Now imagine you take out a binoculars and look at the same scene. Not only is your field of view smaller, but everything is closer and moving faster through that field of view (relatively), including the mountain in the distance.

    tl;dr: star trails are still happening, focal length just determines how big they are.

    It depends on several elements, but mostly the focal length of the lens. Although it's not as accurate for today's large sensors, you can typically use the rule of 500 to determine the exposure length to avoid star trails. 500/(focal length*crop factor). For example, a 24mm lens on a full frame (35mm sensor) can shoot for roughly 20s. The larger the sensor, the shorter you have to shoot to avoid star trails. Aperture wise, you typically want to be as wide as possible (f/1.4-2.8) to gather as much light as possible.

    Thanks bud! Funny we posted our shots on the same day. I was just renting the a7rIII and Sigma 24mm, but they all worked together like a dream. I’ve used the Metabones on my a7 and a6000 before with other canon lenses and they struggled with AF (but that doesn’t matter for night shots).

    Yup! We actually talked about that how we just missed each other. He was just up the way from us that evening.

    This is a questions asked often of Milky Way photographs, and the answer is yes and no. Yes, on clear night skies in dark places, you can quite visibly distinguish our galaxy from the other stars in the sky. It tends to rise in the southwest sky in the northern hemisphere Feb-Nov.

    With that said, it’s also no since cameras and human eyes work much differently. A camera can take long exposures and gather seconds (and even minutes, if on a tracker) of light on its sensor. The more light collected, the more detail and dynamic range available to manipulate in post-processing. These additional details are what allow photographers to really bring out the galactic core,

    I hope that helped answer your question! If you ever have the chance to spend the night, or even just a few hours, in extremely dark places during the new moon in summer, I recommend it.

    With a clear sky and barely visible moon in the forecast, my fiancee and I decided to take a spontaneous trip down to Mt. St. Helens to try and capture the Milky Way traverse over that majestic volcano. I've wanted to shoot astro here for years, but life and weather continued to get in the way. After a fiery 360° sunset, the clouds cleared, unleashing this beautiful night sky. This is part of a 507-image timelapse I took from Loowit Viewpoint that I plan to post later tonight.
