## What is SharpStacker?

SharpStacker turns a series of night-sky exposures into a single clean, detailed image. By aligning and stacking your shots, it reduces noise and reveals faint detail — stars, the Milky Way and deep-sky objects — that a single frame can't capture.

It's built to make astrophotography stacking accessible to everyone: a deliberately simple interface gives you an immediate, intuitive workflow — without the cost or complexity of traditional desktop software.

Full RAW support preserves maximum quality from capture to export. The blending mask is generated automatically by a machine-learning model — or drawn by hand — and can be fine-tuned manually for full control.

• Full RAW import
• Automatic star alignment and stacking
• Noise reduction through stacking
• ML-generated mask, editable by hand
• Simple, immediate workflow
• iPhone, iPad and Mac
• On-device processing — your photos never leave your device

Import your exposures, start the stack, and export a cleaner, more detailed night sky.
