Name: SHJ146
Type: **
Constellation: Vir
Coordinates: 12h31m14.61s / +01°19'37.00"

Components:
m1 m2 ρ θ Year

70mm f/5.7, 33x, Bortle 6, SQM-L 19.5
Visible difference in brightness and color. I couldn't precisely define the colors itself, but A appeared rather orange, B rather bluish.

Pretty wide pair with visible difference in brightness and lovely color contrast. A: pale orange, B: light blue.

STF1670 (**)

Name: STF1670, gamma Vir, 29 Vir, Porrima
Type: **
Constellation: Vir
Coordinates: 12h41m39.60s / -01°26'57.90"

Components:
m1 m2 ρ θ Year
AB 3.5 3.5 2.7" - 2018
55mm f/9.1, 56x
2019-05-18: At 38x slightly elongated. At 56x touching diffraction disks. At 71x clearly separated with very small gap.

70mm f/5.7, 104x, Bortle 6, SQM-L 19.5
2019-05-04: At 47x clearly visible as '8', at 73x split with almost touching diffraction disks. At 104x clearly separated, equally bright and pretty close together. The gap was smaller than the diameter of the diffraction disk.

102mm f/11, 125x
2019-05-01: Extremely nice double star! Equally bright and relatively close together. Both components appeared yellowish-white.
