## What is Zenith Annotation?

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.
