blow it....1645 and I've missed the dusk!!! ...2 lights lower centre and blackness...I'll have to look again tomorrow...
I have timestamped JPEG images at one minute intervals here...
Sunset was at 15:58. It was overcast and raining, so it got dark much quicker than yesterday.
16:05 image shows no degradation.
16:10 image just a little grainy.
16:15 low colour, distinctly grainy
16:20 more so.
16:25 Can still tell sky from earth, but little else.
16:30 Black (and it was indeed dark outside by then).
As unprocessed jpegs the images would exceeded the Forum limits - but 16:10, 16:15, 16:20 and 16:25 are in the attached zip.
I think the WD "daytime only" options are based on sunrise/sunset?
If so it would be handy if instead they either worked from/to twilight or allowed for some user defined bracketing to extend the time to before sunrise & after sunset.
PS. Must remember to turn off the LED (which is what was producing the 2 lights...).
