Depending what time you observed it ,you could be observing it low down
so the colour could be of a reddish ewe.
It comes across to me as a bright white to yellow. |
It is just at 21:00 hours when Eta is high in the sky. And the sky is crystal clear, i.e. no haze. Other O/B/A/F class stars (including stars lower in the sky, such as Acrux) look bluish white as expected.
It may be the star itself is embedded in dust (Homunuculus nebula) which makes the color reddish ?
