this photo unfortunately reveals some issues with this lens wide open- namely halos around bright stars and lens flare around the brightest star (Mimosa Beta Crux)

 

Removed as much of the halos as I could in processing but Mimosa is still very apparent, Could have cropped it out I suppose.

 

Will need to try it closed a couple of stops next time
