You'll be OK is you just array vertically. To tell the truth, at the frequency range where the dispersion slot works, you'd have more problems with center-to-center spacing than astigmatism. But I would suggest against splaying horns like this horizontally and grouping them as a vertical array also. Don't do two rows.
