Personalised · drawn from the catalogue, not a template

The sky over one place,
the night it mattered.

Pick the date, the hour and the city. The chart redraws as you type — every star to the naked-eye limit, the constellation figures, the Moon in its true phase — and arrives as a print-ready file a few minutes after checkout.

Your sky      

Preview is a faithful reduction: same catalogue, same projection (north up, east on the left, as the sky reads overhead), same Moon. The print adds the Milky Way, the planets that were up, and the Explorer key strip.

Explorer names the constellations and bright stars and adds the planets and a key strip; Classic is the plain chart. Nebula is Explorer only.
Your lines all optional
$16.99 Digital file

Print-ready PDF + PNG, 300 DPI, at 18×24 and 24×36 in — any size up to 24×36 prints sharp. Links appear on this page and go to your email within minutes.

Checkout opens on Gumroad: press I want this, check that the Design code field is filled (paste it from below if not), pay. Keep this tab — it shows your download links the moment the file is drawn.

Prefer it framed? Order the printed version on Etsy (8×10 to 18×24; 20×28 and 24×36 here). Paste your Design code (below) into the Etsy Personalization box and the print is drawn from exactly this design.

Design code

Everything above, in one line. On this site it travels with your order automatically. On Etsy, paste it into the Personalization box of the listing — it replaces typing the date, time, place and lines by hand (anything you type next to it still wins).

How it works

Step one

Design it here

Date, hour, place, style and your three lines. The chart redraws as you type; the Design code under the price captures the whole design in one line.

Step two

Buy the file here, or the print on Etsy

The digital file ($16.99) checks out on this page and is delivered in minutes. For a poster or a framed print, order on Etsy and paste the Design code into the Personalization box.

Step three

Approve your proof

Etsy orders get a watermarked preview at thinkdotco.com/proof (the link is in your order confirmation). Approve it or change anything; if you do nothing, it prints 24 hours after the order.

What you receive

Files

PDF + PNG, two sizes

18×24 and 24×36 in at 300 DPI (7,200×10,800 px), vector PDF with fonts embedded, sRGB. Print at home, at a copy shop, or at any online lab; smaller sizes scale cleanly.

The sky

Real positions, not clip art

8,958 stars from the Yale Bright Star Catalogue, the 88 constellation figures, the Moon in its true phase and place, the planets that were up, the Milky Way. Local time is resolved for the place, so 9 pm means 9 pm there.

Delivery

Minutes, on this page

After payment this page shows your download links (live for 7 days) and a copy goes to your email. If a place or date is ambiguous, a person checks it with you within 24 hours before anything is drawn.

Questions

Is the chart accurate?
Yes. Positions come from the same equations an almanac uses (Julian date → sidereal time → altitude and azimuth), on the J2000 catalogue. The horizon is the circle, the zenith the centre, north at the top and east on the left — the way the sky reads when you look up.
Which time zone is used?
The place’s own, including daylight saving on that date. For cities in the list the preview already uses it; for a typed place it is resolved when the file is drawn.
Can I change something after ordering?
Digital file: reply to the delivery email within 7 days and we redraw once, free. Etsy print: open thinkdotco.com/proof with your order number and postal code — you can change the details there until the proof is approved or 24 hours have passed.
Personal use?
Personal and gift use, unlimited prints of your own file. Resale of the file is not permitted.
