Canopus - Alpha Carina low in the south
Second Brightest Star
Uploaded 2/29/24

 
Alpha
            Carina - or Canopus to most rides low on the deep southern horizon
            as seen here in central Arizona. The second brightest star in
            the sky is a bluish-white A9 star, -0.74 magnitude and is only
            outshone by Sirius. This one always catches my attention on cold
            winter nights and so I finally got a shot of it amongst the limbs
            of the pine forest in our area. Technical details: 8" f/2
            RASA, ASI071MC CMOS, 1 minute integration, Payson AZ.
