How much data is needed?

Hi all,

I have started collecting data for the Omega Nebula - I imaged it once only when I just started my adventure with astro and ever since wanted to redo the image.

It will be a narrowband image. I tend to use only Ha for Lum (unless OIII or SII have a good SNR). I already have about 11 hours of Ha and I have been wondering whether I should add another 5 or so hours before I move on to OIII and SII.

Histogram Only: https://www.astrobin.com/full/351798/B/?nc=user

Damaged stars with Local Histogram Equalisation: https://www.astrobin.com/full/351798/0/?nc=user

Thank you in advance for advices/criticism.

Suavi
