SDK Camera Minimum Exposure Time

Postby MikeP » Sat Jan 20, 2018 4:16 am

Good Morning,

I've just implemented the native ZWO driver in my all-sky imaging application and have a question about the minimum exposure time for the cameras. On my particular model (ASI224MC) the minimum that can be set as a value for the exposure control is 32 micro seconds. Is this value a standard for all the ZWO cameras or do different cameras have different values?

Also is it correct that setting the 'IsAuto value for the following controls: Exposure, Gain, WB Red, WB Blue and Bandwidth will only have an effect if you use the camera in video mode (i.e. no effect for snapshot)?

Thanks,

Mike

Hi Mike,
Congratulations。
For min exposure time, It is a standard value for all zwo's cameras. You can set a vlaue samller than it, but we will change it to 32μs in our driver.
About the auto setting, yes, you are right. For Snapshot, shooting is discontinuous, and automatic configuration is a sequence of multiple photos.
Thanks
