Step-by-Step Guide

Step 1 – Create Your Custom Star Map

The first step is to create and personalize your star map. To do so, go to the Star Map Generator app. Then, choose the location, date, and time you want. The generator will show how the sky was at that moment and from that place.

On the free plan, you can configure whether to include the constellations, grid, or frame. You can also choose the colors you want for these elements, as well as for the stars.

After creating, configuring, and theming your star map, click the "Download" button to get it.

Step 2 – Access Your Canva Account

After having your star map downloaded, you need to access Canva.

Canva is an online graphic design platform – very user-friendly and easy-to-use. It provides a large number of templates ready-to-use (for posters, social media, etc). You don't need to be a professional designer to create professional-looking visual content.

If you don't have a Canva account, please sign-up before continuing.

Step 3 – Create a New Poster Design in Canva

Let's get started with Canva. The first thing to do is to create a new poster design. To do so, log in with your account and click the “Create a design” button.

Choose “Custom dimensions” and set the dimensions you want for your poster. You can create, for example, a 50×70 cm poster.

Then, click “Create new design”.

Step 4 – Upload Your Star Map to Canva

Now that you have created your poster design, it's time to upload your star map to Canva.

To do so, select “Uploads”, click “Upload Media” and select the star map image file to upload. Or, you can drag-and-drop the file to Canva.

Then, drag-and-drop the uploaded star map to your poster.

Step 5 – Theme Your Poster Design

Having added your star map, you can leverage all Canva features to theme your poster.

A custom star map poster usually includes:

  • a personalized text message
  • text lines with the name of the location, coordinates, date and time
  • a frame

You can start by theming the poster background. In our case, we are using the same color as the star map's background – an elegant night sky blue.

Then, you can add other map components. In our example, we added a personalised message, as well as the text lines for the location, date, and coordinates.
