Hi Paul,
Very nice shot of that piece of sky it's one area that seems to attract us a bit like a magnet and well worth letting it pull us in.
I have a 135mm f2.8 Pentax lens with very similar characteristics as your f2 lens and it would be one of the sharpest I have but alas that little bit of colour fringing lets it down for astro work the same.

I also have a Limited edition 77mm that I want to use on that same bit of sky if only you'd stop sending those jolly clouds over here from SA

Thanks for showing
