The Panasonic Lumix G100D is a versatile camera, but for the specific requirements of northern lights photography there are a few points to consider:

- Sensor size and sensitivity: the camera has a Micro Four Thirds MOS sensor with 20.3 megapixels and an ISO sensitivity of 200-25600, which is suitable for taking pictures in low light.
- Image stabilisation: The camera has 5-axis hybrid image stabilisation, which is helpful when taking pictures in the dark and with long exposure times.
- Exposure times: The camera allows exposure times of up to 60 seconds, which can be useful for taking pictures of the Northern Lights.

However, it should be noted that the camera does not have any specific functions for astrophotography or northern lights photography, such as an integrated star guide or special exposure modes for these applications.

Overall, the Lumix G100D is suitable for Northern Lights photography, but it might be useful to use additional equipment such as a tripod and possibly a remote control or remote control app to achieve the best quality.
