How it works?

2. Select task from 1. Long exposure 2. Photo 3. Video
2. Adjust the camera setting e.g. ISO, Exposure, Focus and White Balance.
3. Tap Start button.
4. Adjust the MTF slider for brightness during stack task.
5. Tap Stop and it will automatically save in gallery.

Recommendation:
It is good to save a short video and do a live stacking. Having a video give you the flexibility and repeatability to stack the video frame at home on your laptop/phone with different software. A short live stacking gives you an expected image quality for the current sky conditions. A RAW photo of the sky may give you more details than a JPEG photo.

Note:

- You can switch camera by tapping the CAM1 button.
- The long exposure mode comes with auto align and stack.
