Around 21.5 posts per day, measured from the newest 100 posts on Reddit, which span 4.6 days. Posting rate matters more than subscriber count when you're deciding where to spend your time — it determines how long your comment stays visible.
When was r/astrophotography created?
r/astrophotography was founded in October 2009 and is a public — anyone can post community. Age matters: an older community with steady growth has survived Reddit's moderation churn; a young one with a spike may not.
Who posts in r/astrophotography?

Can I promote my product in r/astrophotography?
We don't have a promo-tolerance read for r/astrophotography yet. Default to the safe approach: read the sidebar rules, contribute in threads where you gain nothing, and mention your product only when it is the honest answer to someone's question.
How do I monitor r/astrophotography for mentions?
Hit Watch on this page. Prowlo starts crawling r/astrophotography into your Dataset — every new post indexed and embedded, searchable semantically, queryable by your AI agent over MCP, and able to trigger keyword alerts in Slack. Prowlo is read-only; it never posts on your behalf.
Can my AI agent read r/astrophotography's stats?
Yes. Everything on this page is one MCP tool call away: catalog_get_subreddit returns r/astrophotography's members, growth, promo tolerance and similar communities as typed JSON — free, no credits. Connect your agent to api.prowlo.com/mcp and it can vet the community and start watching it in the same conversation.
