Soul Nebula, 13 hour bicolour narrowband

Recommended Posts

So, I got a new (used) scope a few weeks back and have started testing it now. I think I need to fiddle a bit with the spacing but it looks OK (not perfect). I gathered a few hours of O3 and combined it with some older O3 and Ha from my Sigma 500mm tele lens.

This is 45*5 minutes of Ha and 111*5 minutes of O3.

That's spot on Martin - I like the colour and stretched to perfection
