Shutter control

I was told that there is a hardware limitation for the shutter speed of 60 seconds. Is there no other way to create a plug-in that could control the shutter manually? Why is 60 seconds the limit? I’m a night photographer and see how this would be a huge benefit. Cheers. Jason

I think the max is 60 seconds. I believe you would need to take multiple 60 second shots in sequence and combine them.
