multi-columns bloom sx ccd #532

Closed fcbarclo closed 3 weeks ago

fcbarclo commented 2 months ago

Using Starlight Oculus Pro 180 all sky camera , on a raspberry pi 4 8gb ram, ssd disk, and bullseye os. Latest version of indigo; using indigo_ccd_sx driver. During day it shows multi-columns bloom on the area overexposed. It seems that using the driver indigo_ccd_sx it is not possibile to go under 0.0001 seconds of exposure. The multi-columns like this: attach_1

increases during day , up to completely fill the image like this: attach_3

I know that camera has a fixed gain. But, is it possible to implement a way lower minimal exposure time of 0.0001 ?

I checked the driver and it looks that SX cameras have just millisecond resolution, so shorted exposure time is not possible :(
