At least there are no central obstructions in the theory.
What is
bad CA and what isn't is a matter of personal preference, I guess, so there is only so much reviews can tell you. Stu's old 80mm f11 achro (another AOE scope) was not bad at all but still had some CA. But I wouldn't expect the shorter 90mm to be suitable for planets. Could be nice for wide-field, but then it's dark skies only. Probably better off with a pair of 20x80 binos.
... or if you want more power, get a 4" Mak. Nice clear images, no CA. Lots of detail on Jupiter and Saturn.
Widest it will go with the 1.25" EPs is about 1.25 degrees.
