Study and present your astronomical images on iPhone and iPad. Zenith Annotation brings image import, astrometry, annotations, and presentation tools together in a guided workflow. Explore the field • Open the images you choose from Photos or Files, including TIFF and TIF images. • Solve a field online when you request it and agree to send a working copy. • Browse catalogs and review object and session details. Prepare your annotations • Organize layers, labels, data, and visual styles. • Keep project progress on your device. • Preserve the original file: online solving uses a reduced grayscale copy, not the original. Present your work • Design carousels with editable text, charts, palettes, and animations. • Arrange images and text in collages. • Export a result to save or share yourself. Online solving requires a connection and your explicit action. For this feature, the app sends Astrometry.net a reduced grayscale copy of up to 2048 pixels without EXIF metadata. Zenith Annotation does not transmit the original file or publish your images to social networks.
