in the center of the view, it's true. compared to 8x40 SFL.
sfl itself shows strong purple CA at the edge. especially 10x40.
but aurora have more CA at the end of the edge.
aurora's center CA control can be better then you expected.
really deserve a praise, but I think also it's strong edge CA deserve some criticize.
just around 10 percent but still manage to bother my eyes in some occasions.
when I compared meostar B1+ 8x42 to sfl 8x40, sfl has bit less center CA.
maybe because meostar don't deploy HD lens at 7,8 power.
I wish I could suppress my almost neurotic dislike for CA...life would be simpler. It seems to me the B1.1 10 x 42 will be the best choice for me in the price bracket I have settled on.
