However, in an actual color extinction test at twilight, the SE outperformed the EII by about 8-10 minutes, perhaps because of the slightly larger aperture or more efficient light transmission.
In daylight, the EII looks "brighter" to my eyes.
Hail B'rock son of Gr'lka,
If you were testing the 8x SE and EII, in Cloudy Valley, I would be surpised that 2 mm. difference in aperture would make an 8-10 minute difference in twilight colour distinction. In Copenhagen, or another spot, at a high latitude, such a conclusion would make far more sense.
Happy observing,
Arthur
