Cygnus in the Xiaomi 13 Ultra — 4h 56m integration | 3.2× telephoto + UHC | (post-processing)
This was a collaboration with u/zTrojan: he handled the acquisition and stacking, while I took care of the post-processing.
A deep-field view of the Cygnus region, captured with a Xiaomi 13 Ultra using its 3.2× telephoto camera.
Acquisition
- Xiaomi 13 Ultra — 3.2× telephoto
- ISO 800 | 50s
- 356 light frames (RAW/DNG)
- 4h 56m 40s total integration
- SVBONY UHC filter
- EQ mount with OnStep
- Darks included
- Stacked in Astro Pixel Processor
My processing workflow
- Siril: color calibration, green-noise removal, GraXpert background extraction, stellar deconvolution, and saturation adjustment
- StarNet++: created a separate starless layer and nebula masks for more controlled stretching
- Photoshop: final curve adjustments, mask refinement, Camera Raw finishing, and overall cosmetic corrections
The goal was to bring out as much of the faint structure in the Cygnus Milky Way as possible while keeping the star field under control. The field contains a huge number of targets, including the North America Nebula, Pelican Nebula, Crescent Nebula, Veil Nebula, and surrounding emission and dust structures.
I've also included a region map showing the main objects covered by the image.
Huge thanks to u/zTrojan for the capture and stack — this was a really fun image to work with.
