Kowa 554 vs 774 - CA when digiscoping! (1 Viewer)

Hi, curious why I get CA when digiscoping with a kowa 554 (older model). My 774 gives crisp CA free images. I get same effect with the 554 with phone camera or Amazon type wifi setup.

The CA is not there when looking with naked eye.

Is it the optic and I am just not seeing it when using my own eye? Or is it just a side effect of camera/optic relationship?

Is it the older eyepiece of the 554 and would the newer 55a be better?

The 554 probably star tests better than the 774 but the 774 is super sharp.

Anyway just curious to see if anyone had some insight.
