Sky Quality
Estimate sky quality from captured images
The estimated is calculated as follows
weighted_sqm_avg = (((night_max_auto_exposure - exposure_us) / 10) + 1) * (sqm_avg * (((night_max_auto_gain - gain) / 10) + 1))
Where
sqm_avg - The mean value of the image after the mask and ROI have been applied night_max_auto_exposure - The Night time max auto exposure from the main settings exposure_us - The last captured image's exposure time night_max_auto_gain The night max auto gain from the settings gain - The gain used for the captured image

| Mask Path | The Mask to use when estimatig the sky quality |
| ROI | The are of the image to calulate the sky quality from |
| Fallback | If no ROI specified then use this percentage around the image center |
| Adjustment | Python forumula to apply when calculating the sky quality |
Debug Settings¶
| Setting | Description |
|---|---|
| Enable | When on debug mod is enabled and the Debug Image is used rather than the captured image |
| Debug Image | The image to use to test the module |
