I started not using darks as they were showing up the pattern noise of the sensor - the microlens array. But yeah there is some amp glow there. I applied a dark in an unusual way but its fixed the amp glow now. Thanks for that. A bright left hand edge from a bias was already cropped out so it was just the amp glow. I'll start a thread about this pattern noise because its a pain.

Yeah. KAF16200 is on the wishlist or I can simply whack on the Proline and get it in easily but lose a lot of O3 sensitivity.
