    Is there any way of overriding the 1fps and set an exposure of 30 seconds to do a timelapse of stars?

    The red uses an electronic shutter. The maximum exposure duration is 1/2 second. You can use frame averaging modes in which the camera makes up to 16 half second exposure and combines them into a frame. In these modes you can see the movement of star fields.

    Well

    you won't see into deep space but you can see stars moving over long time lapses.

    For any long exposure work, frame averaging is the way to go. It gives you the longer exposure you want, but it also significantly drops image noise allowing vastly higher ISO without significant penalty. If you're doing a 16 frame average, shooting at ISO6400 looks as noise free as you could want.

    Agreed. I tried frame averaging for the first time a few months ago and it was spectacularly clean.

    Just make sure you black shade for 1fps first to get the best results.

    Can you post image examples to show this feature off?

    Dragon LLO OLPF. I'm stopping down to get the DOF I need for the shots, so that's why I'm using the averaging mode. It works better than even a perfect long exposure as it doesn't just ensure enough integration time to make the correct exposure, but also drastically lowers noise. Most shots there are ISO3200, the darker ones ISO6400.
