SiriusAB finder chart
A finder chart for about 150X to 250X showing Sirius B aka: The Pup in the center. Sirius is not shown, though its centroid is located at the endpoint of the upper line showing proper motion of the binary pair.
The circle showing Sirius B is about 30 arcseconds in diameter. Its separation from the brighter primary Sirius is about 9 arcseconds and there are almost 10 magnitudes difference between them, making this a difficult pair to split.
The larger four or five circles indicating stars at top center show on the observing field sketch I made on Jan. 9th. using the SV152, a Vixen LVW 15mm eyepiece, a 2.5X PowerMate, and an occulting bar eyepiece.
MOUSEOVER: The notes boxes that appear when you hover the mouse over this image show the stars that appear in my Jan. 9th sketch (excluding Sirius A and B).
