### 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](https://docs.astronomyapi.com/requests-and-response/constellation-enums)
{% hint style="info" %}
The 3 letter constellation ID is case sensitive, only lower case is allowed
{% endhint %}
```typescript
{
"style": "inverted",
"observer": {
"latitude": 33.775867,
"longitude": -84.39733,
"date": "2019-12-20"
},
"view": {
"type": "constellation",
"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.
```typescript
// Note how this request does not have the field `style`
// The API will use the default style
{
"observer": {
"latitude": 33.775867,
"longitude": -84.39733,
"date": "2019-12-20"
},
"view": {
"type": "area",
"parameters": {
"position": {
"equatorial": {
"rightAscension": 14.83,
"declination": -15.23
}
},
"zoom": 3 //optional
}
}
}
```
