How did you plan the shot?

This shot wasn’t really planned. I knew I wanted to try and do a panorama but I didn’t know where to go or what to put in the foreground.

One night I went outside and checked the sky to see if it would be worth going out for photos, I saw the clearest Milky Way I have ever seen.

I knew I had to at least try to shoot so I went up the road a few kilometers until I could see all of the Milky Way arch.

I used the website to see what direction the core would be in. The photos were taken at about 10:30 pm.

What equipment do you use?

This image was shot on the Sony A7ii with the Sony 28mm f/2. I used a wireless remote shutter.

I also love to use the Samyang/Rokinon 14mm f/2.8 and the Sony Zeiss 55mm f/1.8.

How did you compose the shot?

This a stacked panorama of 99 different exposures, each exposure being 5 seconds long at f/2 and ISO 6400.

I used a higher ISO because I was stacking to remove noise and it allowed me to use a shorter shutter speed and let me get out of the cold quicker.

What do you do in post-production?

I used Lightroom to do lens corrections and a slight white balance adjustment before I stacked them.

Stacking was done in Sequator to reduce noise with 5 images per stack. I then imported them all to an application called Hugin which takes all of your images and stitches them together to create a panorama.

After the panorama was created I imported it into Lightroom where I made basic adjustments; white balance, tone curve, hue/saturation, etc. I then I went into photoshop to fix some small errors from the stitching.

All of the post-processing took 7-8 hours. Most of my post I learned myself just messing around in Lightroom and some Youtube tutorials.

Can you recommend any learning resources that have worked for you?

I can highly recommend the website Lonely Speck, especially their tutorial on stacked astro panoramas, which is actually where I got the idea for this photo from.
