I'm also in the search for a small refractor around that price and i came also to the evolux 62ed.
I did some research online and like you said; there were a few users who claim there is absolutely no CA with this scope. 🤔
Now i doubt that these pictures were posted straight from the camera without any manipulation whatsoever...
Then i saw this youtube review - (it's in french ; https://youtu.be/CdXmCJdS9HM)
In this review you can clearly see in the pictures taken, that some stars have really bad CA just like yours. (some pictures are better than others)
As he likes some blue colors (stars) in his images; it doesn't bother him but he is aware that this is alot of CA.
So i think there is nothing wrong with your scope, it's just the performance to expect.
So after this video and your post here; i'm really in doubt if i should buy this scope or look for something different.
Anyway, i just wanted to let you know that you 're not alone with this problem.
Clear skies!
