Inspired by a talk by a member of my astro society I have once again found interest in double/multiple stars. He gave a really interesting talk... well ok it's not everyones cup of tea, and explained the different types and formation, etc.
I now feel inspired to create a "ving catalogue of doubles/multiples for newbie" or something with a similar name
. but in the mean time I thought I'd share with you all one of my all time faves, Rho Ophiuchus.
Rho Oph has 4 stars making it a multiple. Funnily enough they form a triangle! Satra A and B (or 1 and 2 depending on where you are from
) form the brightest point of the traingle.
The area is also rich in nebulosity, and wide field astro pics of the antares/ rho oph area are really pretty.
Rho Oph can be split quite easily under low power to get the triangle shape but to split stars A and B moderate powers are needed (3 arc seconds apart).
in a large telescope a certain whispyness can be see of the nebula in the area.
heres a link to the area, as you can see there is plenty in the area to gawk at
