This
is a triple star but I
was able to detect only the brighter components (I used this high power
in
order to darken the sky searching for the 13.5 star). The A-B pair is
easy and
its separation is pretty large. Both stars are fairly bright: the
primary is
yellowish and the secondary is white maybe with gentle yellowish hue.
On the
west of the field there is a very dim star detectable only with averted
vision but its position does not agree
absolutely with the third component. No rings. Extimated PA: A-B
245-250
degrees, A-faint field star about 255 degrees. A pair suitable for dark
skies. |
