Collect Euclid gems!

Azulite (for Azulero + Aladin Lite) is a web interface to extract color Euclid images from a sky map.

The sky map and target selection fields (below) are two ways of specifying the image center and radius.

Target selection

Either center the map on your target and click to set the image radius, or fill the target fields.

Press Enter ↵ or click on Go to target to validate the field values and synchronize the map.

Image generation

Preview a small image or export the full-resolution image as a PNG or JPG file with the dedicated buttons.

For more control (e.g. on resolution or aspect ratio), click the More... button.

Select target
Generate image
Please select a region.
