Uranus and two Astronomical League Double Stars /Uranus si doua stele duble din lista AL

Uranus (center) ,to the S - SE of Zeta Pisci ,on 30 August 2015 in the ''zoth'' 60 x 828 mm
DIY refractor at 33 x / Sirius Plossl 25 mm.
The planet was found first in the 7x50mm ''Mariner '' Fujinon  binocular using the printable version of this ''Sky&Telescope'' map:

A closer look to Uranus using the same ''zoth'' 60 x 828 mm DIY refractor T 207 x ,Kasai 4 mm ocular: a puffy ,very small disc of bluish-grey color in nice contrast with the yellow or light orange star located further to S - SE.

57 Aquilae in the 60 x 828 mm refractor ,easy pray at 33x / Plossl 25 mm.
Look carefully ,to the S -SE there is a much dimmer double star ,about 20% wider
than 57 Aql and with the companion located at PA = 280 degree.

Alpha Capricorni ,a composite view.
In the 60 x 828 mm refractor at 65 x / Solid Simetric 12.8 mm ocular ,
 there are visible the two main bright stars ,located  at PA = 290 degree;
and two really dim companions ,one at PA = 210 deg. and the other at PA = 150 deg.
In the 125mm F/7 Newtonian reflector I noticed a fifth companion ,closer to the bright main star and located at about PA = 290 degree , to the Est of the multiple star system.
