Hi Vasya, you don't mention whether you take any darks etc: if, like me
you don't take them, do you have noise reduction enabled? I ask this because I take most of my subs @6400 with noise reduction enabled, and
DSS has no problem with noise. Incidentally, these images would be
improved if you got your focus spot on.

No darks. I tried to use them in Photoshop but resultlessly. And about noise reducting, what do you mean: in camera or during processing? In camera I switched it off, not to lose sygnal, and about during processing - I tried filters in PhSh but found them not so useful, for me. You think, I need it?
Thanks.
Unfortunately, by the way, M82 is difficult/unreal target for Australia, so our, Northern supernova is only our. However, you, without us, had nova Cerntauri.
If you are not using darks you need to go into the camera's menu and
enable noise reduction. You have to wait while the camera does it's
thing after the exposure, and as the noise reduction takes the same amount of time as the original exposure, it halves the number of images you can get in a given time, but is worth while, and DSS will have no
trouble. Noise reduction does a pretty good job.
