coupla doubles

set out last night under an almost full moon to split some stars. thursdat night has become my regular viewing night now

one of the MOC objects actually has a double sitting right next to it, the pavo glob (its a starfish apparently). this double was bought to my attention by John B in this thread http://www.iceinspace.com.au/forum/s...9&postcount=12 .
the star in question is actually quite easy to find and splits at about 114x tho more magnification will show it better. the star you are looking for will show as a bright star at the edge of the glob and for those who look at everything up-side-down like me it'll be above.

after splitting this i star hopped around for a while looking at nothing in particular then decided to split antares... the seeing wasn't any where near up to it, but i notice in my finder a small triangle of stars and consulting my chart found out it wasn't even in scorpius, it was in ophiuchus.
Rho Ophiuchus is considered a multiple star of 4 parts (A B C D). parts A, C, and D form a very nice looking triangle. A is the brightest of the three so i decided to bump up the magnification a bit on it. This revealed A to be composed of 2 parts of near equal magnitude. A and B Rho Oph showed on my telescope at 114x to be a white, some people see them as golden but the seeing was bad so I saw white C and D are bluish.

I recomend both of these to those who havent seen them before

Nice write-up Ving! Onya! Love the doubles/triples/multiples i dont know if these have been mentioned here before, but My fave telescopic double is actually theta Eridani - yes i know they are millions of nice and interesting ones - But I like these two pearls - the famous bright doubles that make up the pointers and in crux seem to get all the press - and this southern duo never gets mentioned much - so i thought i would just in case you havent seen 'em, sorry if you have! Just for the record my fave multiple is bit more touristy, sigma Orionis.

Orion is one awesome constellation mate for sure - as far as telescopic entertainment goes - its got to be one of the best areas! i look forward to your write-up on Alnitak.
