To retrieve imagery for an observation, use the key:

/api/skymorph/image?key=|001204124410 ...

An uncached image can take a very long time to load, on the order of 10 seconds or more. For faster load times (up to several seconds), use the /fast_image endpoint.

The catch: data used to generate the image is the same, but the sharpness/contrast post-processing is done on Asterank servers rather than the NASA/JPL implementation. In some images, it's possible to lose detail. You should try the endpoints for yourself to determine which is suitable for yoru purposes.
