Sirius is the brightest star in the sky at mag. -1.44 and Sirius B is it's companion at mag.+8.50. For many years it's companion was hidden from view because it's orbit was so close to the magnificently bright Sirius. Only seen on optimal nights with large aperture, but until recently it's orbit is taking it farther away from Sirius making it somewhat easier to see. This past Thursday (3/15/2023), a cold front passed by the night before and brought some exceptional seeing to my observing site (Chiefland,  Fl)... so I took a peek and was blown away at how easy it was to see it's companion. I used a 4.5 Delos at 400x with my 14.5 Starstructure f/4.3

Nice work Raul!  A friend at the observatory had the "Pup" in his 16" and invited me over to have a look.  Pretty cool to see it, but it totally trashed my dark adaptation! lol.gif
