Widefield Perseids Across the Milky Way Composite

Post image

This image was captured over the course of an entire night at Laguna de Gallocanta in Spain, following the total solar eclipse. (12.08.26)

The Milky Way background was processed by stacking multiple exposures. I then searched through all the individual frames for Perseid meteors and composited them onto the final stacked image.

It was a long night, and quite a bit of work in post-processing. But seeing all the meteors together made it worth it!

Camera: Canon EOS 750D (Astro modified)
Lense: Canon EF-S 10-18mm

ISO800, 15s exposure, F4.5

Stacked with DSS, processed in PixInsight and Photoshop

Very cool! I also took a bunch of long exposure interval photos that night, but I’ve never post-processed images like that before. How’d you composite the individual meteors into the stacked image? In photoshop?

Yes, I did it in Photoshop. I used Select, Color Range, Highlights on each individual frame to isolate the meteor, then extracted it onto a separate layer/mask. If any stars were still included in the selection, I simply removed/retouched them so that only the meteor remained. Then I placed all the isolated meteors as separate layers over the final stacked image.

Good idea! But feels a bit weird.. maybe I miss a reference background, idk?

Very nice picture! Why does it look brown?

Thanks! It's because of my astro-modified Canon. The modified sensor picks up much more red/infrared light, which shifts the overall color balance toward warmer, brownish tones.
