Quote:I have an 8 inch SCT (Nexstar) and am wondering what sort of magnification is needed at the moment to catch Sirius B under pretty average skies. If my research is correct it looks almost identical to Rigel, except the primary is obviously brighter, so if I use the same amount of magnification should I then be able to see the Pup, or is there another element to the equation because Sirius is so much brighter.I also bought a neutral density filter which I tested briefly on Rigel and was still able to see the secondary star. But conditions were just awful, Sirius looked like a beach ball even at my lowest magnification
