So a scope I bought earlier this year, the Takahashi FCT-65D, turns out to have an inherent optical flaw in its 0.65x reducer that adds some coma to stars across the frame. I've brought the issue to Takahashi's attention and, after consulting the factory, their answer is that there is no issue! Apparently we're just supposed to be ok with stars that look this way.
My question to the community is: zooming in on the stars on this image, are they bothersome? Would you have demanded a refund for a scope that produced these stars?
Important piece of context: this reducer was specifically advertised to produce round stars across a full-frame sensor.
