Longer Exposure Time of SV305 Camera

When people know svbony is planning the new camera. I received a message: How long exposure time does SV305 have? I will not answer this question now. here are some testing results. Then you will know what you could do with the SV305 camera.

Test 1; 4s exposure time in the black house.

Test 2; 16s exposure time in the black house

Test 3: 64s exposure time in the black house

Is 64s enough for your capturing work? Or it should be longer? So here is my question:

How long exposure time is good enough for a planetary camera? What's your expecting exposure time of the SV305?
