Hi, I want to know if there is a way to use  more than 65 seconds slow shutter or there is a hardware limitation to use more expouse time.

I want to do star photography expousing times arrownd 20 minutes or more.

Thanks in advance for the info.

AFAIK, there is no way to make it more than 65 sec.

But you can take several shots and merge them later in Photoshop or something. (or even in camera, with file browser's "sum" feature).

Remember to disable the camera's dark frame subtraction so you can get the next shot immediately.
