Well it is noisier than ISO800 yes. I'm no guru on the subject but the other night I was out there imaging & like you, I was limited to 35 secs before I got egg shape stars; I tried ISO 800 & wasn't satisfied with the amount of data collected so I jumped to 1600 & tried an exposure of 25 secs. I also tried using darks by both procedures (In camera noise reduction &/or taking a set of darks after the lights) The darks I took after the imaging run didn't kill all the noise but the in camera noise reduction did.
Here's the 1600ISO example. I'm quite happy with this amount of noise!

BTW No noise reduction in editting was done with the image, just the noise reduction from the camera.
