Description

AstroLens turns your iPhone into a fully manual astrophotography camera, designed for afocal shooting through the Vaonis Hestia smartphone telescope.

THE PROBLEM IT SOLVES

When your iPhone sits on a telescope eyepiece, the native Camera app silently switches from the telephoto lens to the wide lens with a digital crop, because autofocus cannot converge through the optics. AstroLens locks the physical lens of your choice (the optical telephoto by default) and never switches away from it. Zoom stays at 1.0×: pure optical magnification, no digital crop.

FULLY MANUAL, FULLY DETERMINISTIC

Manual focus slider with focus peaking and a magnifying loupe

One-tap mirror flip to correct the telescope's inverted image (preview and captures)

Manual shutter speed and ISO, bounded by the real sensor limits

Locked white balance for consistent colors across shots

Live histogram to nail the exposure

MADE FOR THE NIGHT

Sun, Moon, Landscape and Deep Sky modes with sensible starting presets

Mandatory solar-filter confirmation before Sun mode

Crosshair, telescope-field circle and composition grid overlays

Red-on-black night theme to preserve your dark adaptation

2-second self-timer and volume-button shutter to avoid vibrations

Apple Watch remote shutter: trigger from your wrist without touching the iPhone, with the mode, shutter speed and ISO on your watch

Burst capture for stacking deep-sky images

Apple ProRAW support (on compatible iPhones) plus HEIF

Captures saved to a dedicated “Hestia” album

FIND YOUR TARGET

Sun/Moon alignment assistant: on-screen arrow plus turn and tilt guidance, computed from your location and the phone's motion sensors, fully offline

Works uncalibrated right away: the compass gets you close on its own; then center the target once in the eyepiece view and tap Calibrate for degree-level pointing

Adapter geometry is configurable (Hestia's mirrored optics by default)

AstroLens works on any recent iPhone: without a telephoto lens it locks the main wide lens instead, still with zero automatic switching.
