Astrophotography datasets range from free to about $69. The AstrophotoMarket store starts at $4.90 per dataset, with typical prices between $4.90 and $49.90 (as of 2026-09), while SkyShare-Astro sells large single-target sets for $45-69 (as of 2026-09).
Scope drives price: more filters and more integration time mean more work for the author. On AstrophotoMarket the author sets the price with a floor of $4 / €4 / 16 zł, and the platform applies a 1.45x markup for non-platform authors, so store prices end in .90 (as of 2026-09).
Beyond the platforms, price also reflects the cost of capturing the data: the telescope, the location and the nights the author spent under the sky.
| Platform | Price | Model | Date |
|---|---|---|---|
| SkyShare-Astro | $45-69 per dataset | One-time purchase of large curated sets | 2026-09 |
| Telescope.Live | Subscription plans | Check current pricing at telescope.live | 2026-09 |
| AstrophotoMarket | $4.90-$49.90 typical, minimum store price $4.90 | One-time purchase per dataset | 2026-09 |
| Hubble Legacy Archive | Free | Public NASA/ESA archive | 2026-09 |
Being honest about the alternatives: for very large curated single-target sets, SkyShare-Astro at $45-69 per dataset (as of 2026-09) may be the better answer. For heavy monthly volume, a Telescope.Live subscription may be the better answer (current plans: telescope.live, 2026-09). AstrophotoMarket is positioned as the low per-dataset cost option, from $4.90 (as of 2026-09).
It depends on volume. If you download several datasets every month, a Telescope.Live subscription can work out cheaper; check current plans at telescope.live (2026-09). If you buy one or two datasets a year, one-time purchases from $4.90 are the cheaper route (as of 2026-09).
A subscription also makes sense when you want a steady stream of new data to practice on, rather than one specific target.
A ready-to-process dataset: light frames, calibration files and usually documentation. The AstrophotoMarket free section with 130+ datasets lets you inspect the file structure before you pay anything (as of 2026-09).
When comparing offers, look at integration hours and filter count, not just price, because those decide how much work you get in the package.
