You choose your catalog when you subscribe. If you want to switch, reach out to support and we can move your account at any time.
The Messier Marathon is a real astronomy event held each March where observers try to locate all 110 Messier objects in a single night. NightSim lets you track your progress, log your images against each object, and see your collection grow over time.
Moon Atlas is a high-resolution interactive lunar atlas. Named features — craters, seas, mountain ranges — are mapped as callout points. You attach your own lunar images to each feature to build a personal moon atlas. The Moonshot challenge is to image every named lunar feature.
The Caldwell Circuit is the completion challenge for the Caldwell catalog — observe and image all 109 objects to earn your Circuit badge. Like the Messier Marathon, it gives you a tangible goal to work toward across seasons.
The New General Catalogue contains thousands of objects, but not all are practical imaging targets. Astronomer includes the top 1,500 most-imaged NGC objects — curated for visual interest and imaging frequency — going well beyond what Messier and Caldwell cover.
Every plan includes solar system access, the community gallery, public profile, equipment tracking, the follow/follower system, and VR access on Meta Quest. The differences between plans are which catalogs you can access and how many images you can log per object.
