Seeing is king.

Fainter stars and nebulosity are patently visible on nights of good seeing and transparency.

The narrower bandpass, the less the effect of skyglow. (this is why sub-angstrom Solar filters work so well)

What bandpass are you using? (not stated in the video)

I'd expect to see a minor difference at say, 12nm, but not at 5nm or 3nm
