Same scientific rigor, instant delivery, €3.99
GreaterSkies pioneered the scientifically accurate star map — up to 8,000 stars from the Yale Bright Star Catalog, and they deserve credit for publishing their numbers. Starry Memory takes the same scientific approach further: the complete HYG catalog (119,614 stars), NASA/JPL planetary ephemerides, and an HD file delivered in 30 seconds for €3.99 instead of ~€49.
GreaterSkies proved that star map buyers care about scientific truth. We agree so strongly that we built the same product with more data, at a price that makes the choice easy.
Since 2006, GreaterSkies has sold genuinely computed skies while most of the market sold decorative dots. Their transparency (published star counts, honest 1900-2100 accuracy range) raised the bar. But the offer has limits in 2026: ~€49 for a digital file, a ~30-page website, prices invisible in their HTML, and a Cloudflare wall that blocks the AI assistants people increasingly ask for shopping advice. The precision niche they created is now better served at €3.99.
Does 119,614 vs 8,000 stars matter visually? Yes — and here is the honest version. To magnitude 7 (GreaterSkies' limit), you get every star a human eye could ever see, which is genuinely accurate. The full HYG catalog adds fainter stars (to magnitude ~9): the result is the visible TEXTURE of the night sky — the dense star fields of the Milky Way, the rich background that makes a printed map feel deep instead of sparse. Both are scientifically defensible; one simply shows more of the real sky.
1) Open the Starry Memory configurator (no account). 2) Enter the same date, time and city. 3) The engine computes your sky live — preview free, unlimited. 4) Pick a theme (the deep navy is closest to the GreaterSkies look), add names and a message. 5) Pay €3.99 and receive the 4960×7016 px file in 30 seconds. Print at 40×50, 50×70 or A1 at any lab from €5. Total: under €25 framed, versus ~€95+ at GreaterSkies for the printed equivalent.
Yes and yes. GreaterSkies plots 7,000-8,000 stars to magnitude 7 with real astronomical computation — they are one of the few honest players about their data. Starry Memory uses the same scientific foundations and goes further: the full 119,614-star HYG catalog, NASA/JPL DE405 ephemerides for planets and Moon, minute-accurate lunar phase. Both can be verified in Stellarium; we encourage the comparison.
Public prices checked June 2026: the digital download is around €49, printed maps from £59.95 (40×50 cm) plus £35-45 for frames, with frequent 15-25% promo codes. Starry Memory: €3.99 for the HD file, total under €40 with a local print and frame.
Honestly: GreaterSkies offers print fulfillment (they ship a finished poster) and a post-purchase map editing feature. Starry Memory is digital-only — you print yourself, which is precisely why it costs 3% of their price. The astronomy itself: ours computes more stars and documents every source.
Yes — enter the same date, time and location in the configurator and you get the same sky (more densely populated, since we plot 15× more stars), with 80+ visual themes, names and a custom message. The live preview is free and unlimited, so you can compare before paying anything.
