Star Eater: Astrophotography with the a7s, a7RII, a7SII, a9 and a7RIII – An Open Letter to Sony

star-eater-why-i-no-longer-recommend-sony-cameras-for-astrophotography

Sony makes excellent cameras. In the last few years, they launched a completely new full frame camera system that has pushed the bounds of digital photography. I switched entirely to Sony gear after first seeing the tremendous low-light capability of their a7S and have enjoyed many outings shooting astrophotography on many different Sony camera bodies since. I have previously recommended Sony gear to countless numbers of fellow photographers looking for the best landscape astrophotography cameras. Now, I’m hesitant to recommend Sony’s latest cameras due to a problem that affects astrophotography. Before you buy a new Sony camera, be aware of this issue.  Continue reading

How I Planned and Shot an Erupting Volcano with the Milky Way by Albert Dros

Albert Dros has been a great friend to Lonely Speck over the last few years, sharing with us his experiences shooting landscape astrophotography around the world. We had the pleasure of meeting him in his native environment of the Netherlands when we traveled through Europe last spring. A few weeks ago, Albert messaged me about his plans to photograph the Milky Way behind an erupting volcano. In this article, Albert Dros recounts his personal experience planning and shooting the Fuego Volcano in Guatemala.

How to Find the Best ISO for Astrophotography: Dynamic Range and Noise

how-to-find-the-best-iso-for-astrophotography

ISO is one of the three major exposure settings in the exposure triangle of a digital camera. Of the three: shutter time, f/number, and ISO, it is ISO that is probably most misunderstood. Even more so than f/number. In fact, it is a common misconception that higher ISO settings will cause images to be noisier. In fact, the opposite is often true. Wait, what?

That’s right, higher ISO settings alone do not increase image noise and higher ISOs can even be beneficial to low-light photography. In this post, I talk about the craziness surrounding ISO settings, how ISO actually affects exposure and how to find the optimal ISO setting on your camera for astrophotography.
