NiSi Filters 0.9 | 6-Stop | ND8

This filter serves the same purpose as the 10-stop, but it is better suited for sunset and sunrise. When the sun is close to setting or rising, a 10-stop ND will require a very long shutter speed at f/11-16 and ISO100 to produce the correct exposure - often as much as 5-10 minutes. A 6-stop ND is thus much more suited for capturing long exposures of 30-60s around sunset and sunrise.
