Hi everyone

Struggling with reflections. Here's an example after sigma clip stacking; still there. I wonder if there's a filter I could use to reduce the reflections. It's a Takumar 135 f3.5 which apart from the reflections, is very good. It is one click closed from maximum aperture. Below is my attempt to heal them, It works to a certain extent, but I'd rather cure them at source. 

Thanks for looking and any tips on reducing those reflections most gratefully received.
