New Messier Catalog App
All 110 Messier objects, photographed from my backyard under suburban skies.
I've put the whole set into a free app. Every object full screen and zoomable, with its type, constellation, distance, a description, and Messier's own notes from the 1770s. You can mark what you've observed and what you've imaged, so it works as a checklist too.
Free, works completely offline, no account, no ads, no data collected.

If you find it useful, a positive rating and review helps a lot. Happy to answer anything about the imaging.
