Very very fine resolution. What is the dark band along the bottom though?

I have used ISO6400 and 25600 on the D800E and it worked fine. A bit of noise at ISO25600 starting to intrude.

I would think ISO6400 could easily be standard for a D800. It will require a small amount of noise control but if you stack in particular and use darks and flats then it should be fine.


Greg.

Thanks Greg - the dark band isn't in any of the subs, so I think it's an artefact from DSS. I've got a 6 core computer with 32Gb RAM and 2 256Gb SSD drives being delivered this week, and I'm moving to Pixinsight, so I'll finally get a chance to see what I can squeeze out of these data.
I've resisted going too far into digital processing because it's too similar to what I do for a living, but in for a penny, in for a pound...
