This is not an easy target and you've done a good job from a light polluted area.  Another 8 hours!!

If your sky is predominately orange from sodium lights rather than grey from LED lights then a light pollution filter would help with emission nebulae like this.  The IDAS P2 filter is best but it's pretty expensive now because of Brexit:

It avoids the colour casts that the Astronomic CLS filter has.

However, the days of light pollution filters are numbered now - they are useless against the glow from broad spectrum LED streetlights.
