Hi,
I have an ASI2600MM Pro and a ASI290MC Mini and both have these "Fast Exposure" and "Fast Count" features under their INDI Control Panel Options tab. I think I know what "Fast Exposure" does, but it doesn't always do that, so I'm not sure. Also, the "Fast Count" - hmmm... Anything that is labeled "fast" looks like a good thing, so it would be useful to know what they're for. Looked under www.indilib.org/individuals/devices/came...ics-asi-cameras.html, but there's no info.
