Personalized Star Map in California
CA · Custom Night Sky Print
Give the exact sky that hung over a California address on the date that matters — wedding, birth, first date, anniversary, memorial. 8,921 real stars from the HYG v4.2 catalog, 88 IAU constellations, rendered at 300 DPI for any city in California and across the United States.
What is a California star map?
A California star map is a personalized print showing the precise night sky over a chosen California city on a chosen date and time. It uses the HYG v4.2 stellar catalog of 8,921 naked-eye stars and the IAU local sidereal time formula, so the constellations on the page match exactly what was overhead. Customers in California most often order them for weddings, births, anniversaries, and memorial gifts — from Los Angeles to Long Beach and every town in between. California is America's observatory state. Mount Wilson Observatory above Pasadena hosted Edwin Hubble's 1924 discovery that the universe extends beyond the Milky Way. Lick Observatory on Mount Hamilton, founded in 1888, remains the world's first permanently-occupied mountain-top observatory. Death Valley International Dark Sky Park delivers Bortle 1 skies just a four-hour drive from Los Angeles. The result is delivered as a 300 DPI A3 PDF (4960 × 7016 pixels) for instant download, or as a premium archival print shipped to any California address in 5 to 8 business days.
Cities we map in California
Each city below has its own dedicated star map page with local landmarks, recent customer reviews, and the precise latitude/longitude we use for rendering. California addresses outside these cities work in the designer too.
Why a star map of California
From Pacific fog rolling under the Golden Gate to the Mojave's high-desert stillness, California's coast-to-mountain geography produces some of the most varied night skies in the country. A California star map can frame a beachfront wedding in San Diego, a foggy June engagement in San Francisco, or a Joshua Tree birthday — each radically different overhead.
The print itself is rendered server-side from real astronomical data — not a stock illustration. That means a California star map for August 15 looks meaningfully different from one for February 15, and a Houston sky on a given night looks different from an Amarillo sky the same hour, because both the date and the precise coordinates feed the calculation.

Frequently asked questions
Can I get a star map for any city in California?+
Yes. Our system covers every named US town with geographic coordinates, not just the cities we feature on this page. Type the address or zip code in the designer, and we calculate the precise night sky overhead — anywhere in California, anywhere in the United States.
How long does shipping take to California?+
Standard ground shipping to California runs 5 to 8 business days from our US fulfillment partner. Express options reach most California addresses in 2 to 3 business days. The digital PDF version is delivered by email within minutes of checkout — no shipping involved.
Does the night sky really look different from city to city in California?+
Yes, meaningfully. Your latitude shifts how high the constellations sit in the sky, and your longitude shifts which constellations are overhead at a given clock time. A star map for a date and time in El Paso looks visibly different from the same date and time in Brownsville. Our renderer respects both — using the IAU local sidereal time formula and the HYG v4.2 stellar catalog of 8,921 naked-eye stars.
What date should I pick for a California star map?+
Any moment that matters. Wedding day, the night a child was born, the evening of a first date, a grandparent's milestone birthday, a memorial date. The most common picks are the date itself at around 9:00 PM local time — late enough for the constellations to be clearly above the horizon, before the post-midnight sky has rotated too far.
Can I order both a digital download and a printed poster?+
Yes. Many California customers buy the digital PDF first to preview and approve the design, then come back for a printed poster as a gift. Both are available from the same configuration — your customization is saved against your email.
