What would you do? Tips, suggestions, etc please!

So I'd like any tips or suggestions people might have, or to hear about what you would do in my position.

I'm planning on capturing the Orion nebula in Bortle 2 skies with a Seestar S50 and an Askar Colour Magic C2 (SII-OIII) filter tomorrow night at 60s exposures. I did a test run in Bortle 4 skies last night at 30s and it seemed to work pretty well, didn't have any issues. Both the test and the planned capture were/will be in EQ mode.

I'm just wondering if 60s seemed optimal? Would it be better to do 30s? A mix of both? Is there anything I'm missing or overlooking that I should do or consider? Would anyone suggest another target that they think would particularly shine for this simple set up?

I also have a powerbank for a longer shoot time.

I don't know exactly how long I'll be out there. I suspect at least 4 hours but shooting for somewhere closer to 5-6 from 8pm onwards.
