Easily apply optimal settings for red nebulae or starry landscapes, adjust saturation, highlights, and shadows, and save your favorite profiles.Why Handheld High Res on a Tripod?High Res Shot uses in-camera stacking to produce higher-quality images with greater detail and reduced noise.By capturing and compositing multiple frames, OM SYSTEM’s High Res Shot function generates ultra-high-resolution images. While Handheld High Res Shot is typically used without support, fixing the camera to a tripod or equatorial mount allows astrophotography-style stacking to be completed in a single in-body process. This approach increases resolution and corrects star movement or tracking errors, resulting in cleaner, sharper images.Tip:When shooting fixed on a tripod, set the shutter speed so that the exposure time per frame is such that the stars appear as dots.Remotely capture flawless night-sky shots with perfect stabilityUse the OI.Share app or RM-WR2 remote controller to capture stars with pinpoint accuracy. Shoot long exposures, timelapses, and high-resolution astro images without touching the camera, keeping every frame sharp and stable.RM-WR2 Wireless Remote Control ReleaseWirelessly control your camera via Bluetooth using the RM-WR2 for precise, stable night-sky photography.The free OI.Share AppWireless remote control, camera live view on your mobile device screen, and browsing and importing images—even with the camera in your backpack.
