IC434 - Horsehead in two versions

Recommended Posts

I started this project back in mid-January with 50 minutes of Ha data. I've been adding more data to it recently and I'm now up to 4h05m in total, consisting of:

  • Ha = 1h40m
  • Oiii = 1h25m
  • Sii = 60m

I've processed what I have to date and have a couple of copies, the first is an HOO version with 2h40m integration and the second is SHO version using the Ha as Luminance for the combination.


  • SkyWatcher Evostar ED80 DS Pro with 0.85 FF/FR
  • Atik 428EX Mono
  • Atik EFW2
  • HEQ5 with Rowan Belt conversion
  • Baader 7nm Ha
  • Baader 8.5nm Oiii
  • Astronomik 12nm Sii

I want to add more Sii data on the next clear night, but here's what I've got so far:
