Amlan, We shouldn't turn it on when shooting startrail. Already, my cam takes about 7-8sec between shots. If I turn on, it will take even more time (equivalent to exposure duration).
I am using a compact camera. Pushing ISO anything above base ISO will introduce noise + extended/continuous use & long exposure introduces thermal noise + my expertise in image editing introduces majority of the noise you see . Deepskystacker have an option for that. Uploading dark frames along with the light frames helps to reduce noise. Even @ ISO 1600, I could get clean images.

That purple colour may be because of my choice of white balance, I guess.
