Description



Little by little I have managed to reduce tilt between my CCD and the Cnon EF 200mm f1.8 lens.

At f1.8, every single micron makes a big difference. Working with an extreme fast lens, like this, is very demanding. Tolerances are very small, the critical focus zone is only 7microns, that's 7/1000mm!

Other channels, O-III and S-II are taken from an older image from year 2008. Star colors are borrowed from an RGB-image, shot at 2007.
