You got a screenshot taken from said OP without credit right there
to the stacking issue
Cels and backgrounds being stacked wouldn't just be it, there also had to be keying involved (which can be done on film)
from what I see here, this IS a single cel Luna-Art's Cel Gallery - Sailor Moon - Bank: OP/ED
It's the backgrounds that have to be keyed out and stacked separately to complete such a shot.
I've done a simpler (and yet more layered) version of this when animating/editing the Tokyoma Gaiden opening, (Prepare for Photodump)
The six separate elements
And the final composited image, done with luma keying:
My guess is they did a somewhat similar trick to get the three separate backgrounds for Moon, Mercury and Mars in that shot.
Sorry for putting my screenshots on here, I did it just to illustrate what I think they did.
