What magnification do I want for deep sky?

I have an 8" f/6 dob. I presently have a 40mm eyepiece for wide field
observing giving me 1.6 deg TFOV, 30X mag, and 6.7mm exit pupil.
Unfortunately, I live in seriously light-polluted suburbs, so the sky
is just too bright (mag 4 on a good night). Often, I can't even see
M31. I'm thinking of getting a wide angle eyepiece in the 26-32mm
range. Should I do this, get a filter, or something else?

Thanks in advance,
Greg

P.S. I'm pretty sure my issue isn't related to heliocentricity, Justice
Alito, or coal :}

    ... Your pupil probably dilates to somewhere between 5 and 7 mm in diameter, depending on your age. ... Your telescope has an f/5 focal ratio, so the exit pupil would be about 6mm. ... The telescope maker's choice of 25mm and 10mm eyepieces for this telescope is a good one: a 10mm eyepiece gives a 2mm exit pupil for maximum visibility of faint objects and a 25mm eyepiece gives a 5mm exit pupil for wide-field views which viewers of all ages are likely able to take in. ...

So, in effect, having an eyepiece exit pupil larger than your eye pupil, reduces the aperture of your telescope, dimming down the image. ...
