What is the Sharpcap setup for ASI120MM to capture image 300s exposure time.
So far if I try greater than 4sec my picture is overexposed even with gain = 0.
some of my friends using ASI120MM for long exposure，usually take 15s-60s for single shot. I think gain=10 of ASI120MM is better. This sensor is not suitble for 0 gain.
