Eta Carinae - mucking around with zones

Hi all

I'm starting to delveinto the book I bought the other day - Zone System for Astro Imaging.

It's prety comprehensive, and it'll take a while to get my head around the zone technique - especially for RGB colour. I've done a couple of monos and I'll put them up shortly.

Anyway - here's a re-process of a stack of two images - one from my Nikon D40 and another from my 350D. I selected the dark zone and deleted most of it - and smoothed the dim zone. Noise isn't too bad for two DSLR images stacked I think. Sharpening the bright zone is a challenge though - artefacting occurs very quickly - probably not helped by cramming it into 200kb to put up here. Anyway - good fun as usual.
