This is the
latest
I should know better than to post in the deep space section at this stage of the game. This is the latest rendition of Antares Rho Ophiuchus widefield. If anyone is interested using a flat with no bias correction eliminated most of the banding and gradients that come with the 1000D. It took a while to work out what was going on. In the end it came down to calibrating a single image with various combinations of master frames. Better viewed at lower resolution.
