Hi, I am new to refractors and have a problem with my WO 71mm Star f/4.9. If bright star is in FOV I get this horrible halos/fringing. Isn't that supposed to happen only in doublets? uncalibrated example of problem is in attachment, left star is the worst (taken with Sony A7r, 120s exposures) Thanks!
