This lens has best difraction limited optical quality I have seen.
Lens is used in SuperWASP project, actually eight of them:

The model I bought is electronically focused, so there is no mechanical link between lenses and
focusin ring. After lots of thinking I ended up to modify the lens for the astro work.
Opening up and messing with electronic and mechanic of the expencive lens was not a
easy decision, but it was the only way to use it with my new astrocamera, QHY9.
