@apinkney97, Alex, I'm curious why you are using a GitHub commit rather than a release? The commit you have is for the next release, so I'm surprised it's even working on the release you have. |

Hi @EricClaeys , thanks for replying. I guess I was wondering why these were the default settings. Maybe there is a reason it's this way that I haven't understood?
I followed the installation instructions here, which tell you to clone the repo, so I ended up with whatever |

The defaults work fairly well for many people, who generally expect night pictures to be darker than day pictures. Most people take around 60 second night pictures because anything longer tends to produce star trails and hence look unnatural. By the way, welcome to Allsky! I think after you have it running the way you want, you'll find it's pretty nice. |

Hi, I'm a new user. I have allsky running on a Pi 5 with an HQ cam, on commit 478f3e6.
I haven't changed any of the default settings except enabling
Daytime Save.When allsky switches from daytime mode to nighttime mode, the exposure time seems to drop, when I'd have thought it would increase.
Here's an excerpt from the logs around the switchover time:
Details
and here is an overview of the images captured:
The slightly brighter image (row 3 column 2) is
image-20240724214700.jpg, the first one of night mode, with 809.13 ms exposure time. The next image is much darker, with only 38.62 ms exposure time. As you can see the exposure time goes up to around 300 ms, but it seems strange to me that this is still a lot less than the exposure time at the end of daytime mode.Is this expected behaviour or a bug? Are there some settings I should change?
For reference here's my
