Yes, take it off for galaxies. They're broadband, so the dual-band filter throws most of their light away. Keep it for emission nebulae.

Seestar S50: dual-band filter on galaxies, yes or no?
Started by @m31_mateoLv 3
I've been leaving the LP filter on for everything because my sky is Bortle 6. Is that hurting my galaxy pictures?

Same sky as you. Filter off and twice the integration worked much better for me on M 81.
Thanks both, trying it tonight on Andromeda.
