Rendering different views

Constellation

To generate an image of a constellation the type in the view object must be set to constellation. The 3 letter ID of the constellation must be passed in the parameters for the view object. For a complete list of constellation IDs see Contellation Enums

The 3 letter constellation ID is case sensitive, only lower case is allowed

    "observer": {
        "latitude": 33.775867,
        "longitude": -84.39733,
        "date": "2019-12-20"
    },

        "parameters": {
            "constellation": "ori" // 3 letter constellation id
        }
    }
}

Area

To generate an image of an area in the sky, set the type to area, then pass the RA and Dec values in the position object for the view parameters. Currently equatorial coordinates are supported by the API. Additionally the parameter zoom can be provided to scale the image, but it's optional.

// Note how this request does not have the field `style` 
// The API will use the default style
