Astro Capture

Turn your smartphone into an astrophotography camera.

Leave the laptop behind. Astro Capture runs your ZWO ASI astronomy camera straight from your Android phone or tablet — no PC to haul into the cold, no bulky setup, no laptop battery dying mid-session. Connect the camera, frame your target and start shooting in seconds.

Image the Moon, planets, the Sun and deep-sky objects, and save everything in the formats your stacking software expects — TIFF, FITS and SER — ready to process at home. You get full manual control of exposure, gain, resolution and more, in a clean red night-vision interface that protects your dark adaptation in the field.

Why Astro Capture:

- No laptop required — your phone is the screen and the controls, ready in seconds

- Travel light to dark sites — leave the computer, table and cable tangle at home

- Keep shooting longer — charge from a power bank while you capture (USB PD)

- Dark-sky friendly — red night-vision theme across every screen

- Real data out — RAW TIFF / FITS / SER for stacking and post-processing

- Simple and focused — none of the desktop-software complexity

F.A.Q.:

Q) I can't connect to the Camera to my Smartphone

A) When the camera is connected, the smartphone may refuse to power it due to the high peak current required. Connecting the cable to your smartphone first can help due to the capacitance of the cable.
