Photographing the Andromeda Galaxy for 10 Seconds vs 10 Hours<\/p>\n
This video<\/a> by Ian Lauer is an excellent accessible explanation of the basics of astrophotography as he runs through the process of how he captures a long-exposure image of the Andromeda galaxy.<\/p>\n This picture is still black and white \u2014 and no, the galaxy is not devoid of color. There\u2019s actually color in there, and we\u2019ll get to color in a second. But first, let\u2019s look at what happens when I zoom in on this image.<\/p>\n You can see there\u2019s some graininess in this image, which we call noise. And we hate it because it prevents you from seeing more detail in your image. To combat the noise, we can take multiple images of that same target \u2014 so, one after the other \u2014 and stack them together using software to average out all of that background noise.<\/p>\n Take a look at what happens when we do that. This image isn\u2019t just a single 1-minute image but 10 1-minute images stacked on top of each other. Look how how much better, how much cleaner, it looks when compared to the single 1-minute image.<\/p>\n There are a bunch more videos on Lauer\u2019s channel<\/a> to check out, including Shooting the Milky Way from Every Light Pollution Level<\/a> and The BEST Telescope for Beginners<\/a> (he recommends the Seestar S50 Astronomical All-in-one Smart Telescope<\/a>, which many other people recommended on social media instead of anything on this list<\/a>). Oh, and I\u2019m gonna watch this one about astrophotography with the iPhone 17 Pro<\/a> right now.
