Hi
I managed to get some Ha data on NGC2024 earlier in the week, This was taken with the FSQ106ED at f5 with a Starlight Xpress SXVF H9 on a Paramount ME, it was 12x20 minutes auto guided by a lodestar camera using dithering. I last tried this subject 4 years ago with my previous Meade LX200 system, this can be seen on the Nebulae page of the image gallery of my website

Thanks for looking
Best wishes
