Mobile Astro Observing Log

About Mobile Astro Observing Log Android App

Replace your paper logging with this mobile-based logging app. It includes a normal mode as well as a night mode, which gets rid of virtually all white light and is usable in the field while observing.

Install up to 13,000 objects (Messier, NGC and IC catalogs included). Search and filter or just browse the catalogs. Each star chart (normal and night) includes 1, 2 and 4-degree finder circles and each object display screen includes essential data about the object.

Log the date, time and location of observation as well as equipment used, seeing, transparency and text notes. Backup and restore your data to move between devices, or export to an HTML file that can be printed and submitted for observing awards.

Create target lists, user-defined lists to help you organize a night's observing. Add an object to one target list or multiple target lists. Mark an object as a favorite for future reference.

Manage your favorite equipment profiles and favorite observing locations for quick logging. And even use your device's GPS to pre-populate the location field.

This app is free and includes donation functionality. I hope you like it, and if you think it's worth a dollar or two I won't turn it down
