NIGHT SKY / IMAGING & SOFTWARE

From the sky.
Through the process.

Astrophotography brings two parts of my work together: capturing the night sky and building Nightpipe, my app for turning raw frames into finished images.

01 / PHOTOGRAPHY

Looking further.

I take astrophotographs and share my work on AstroBin, as well as through stock photography platforms.

02 / AUTOMATED PROCESSING

Nightpipe.

From a night of raw frames to images ready to review. Nightpipe automates calibration, stacking and processing for one-shot-colour astrophotography, using Siril for the core image work.

It groups frames by target and night, reuses calibration masters, grades and aligns exposures, then stacks and processes the results. A personal project built around my own imaging workflow.

03 / NIGHTPIPE

Capture all night.
Review in the morning.

Start with the folder your rig syncs to. Nightpipe takes each session through a repeatable workflow, with a local web interface when you want to check in.

⌗

01 / ORGANISE & CALIBRATE

Begin with the raw frames.

Read target and night from FITS headers, group the exposures, and build or reuse bias, dark and flat masters for calibration.

≋

02 / ALIGN & STACK

Bring the session together.

Grade and register frames, reject poor exposures, and combine the rest with weighted stacking and outlier rejection.

03 / PROCESS & EXPORT

Find the finished image.

Remove gradients, reduce noise, and compare stretch and colour variants. Export 16-bit TIFF, PNG and JPEG. Dual-narrowband sessions can also produce HOO composites.

04 / LOCAL CONTROL

Check in when you want.

Browse the inbox, run or cancel sessions, follow progress, edit settings, and re-render with a different stretch from the local web control panel.

◷

05 / UNATTENDED RUNS

Keep the workflow moving.

Use the same processing pipeline from the command line or folder watcher. Designed for Windows alongside the rig, with macOS and Linux support.

06 / PROCESSING TOOLS

Work with available engines.

Siril is required. Optional GraXpert, StarNet2 and licensed RC-Astro tools add processing options. Available fallbacks are used where supported; unavailable deconvolution is skipped.
