25 CVn (**)

Name: 25 CVn
Type: **
Constellation: CVn
Coordinates: 13h37m27.70s / +36°17'41.40"

Components:
m1 m2 ρ θ Year
STF1768 AB 5m0 7m0 1.7" 95° 2017
STF1768 AC 5m0 11m6 214.3" 321° 2015
KZA73 AD 5m0 13m0 335.6" 92° 2015
KZA73 AE 5m0 12m7 369.5" 139° 2015
KZA73 AF 5m0 9m4 437.3" 118° 2015
102mm f/11, 160x, Seeing 3/5
AB: 2020-03-09: At 160x despite mediocre seeing the clearly fainter companion is immediately conspicuous as small, roundish brightening close to the first diffraction ring of the primary component. At 224x the companion appeared partly slightly elongated. Overall quite easy.

STF1692 (**)

Name: STF1692, 12 CVn, alpha CVn, Cor Caroli
Type: **
Constellation: CVn
Coordinates: 12h56m01.67s / +38°19'06.20"

Components:
m1 m2 ρ θ Year
AB 2m9 5m5 19.3" 229° 2017
70mm f/5.7, 22x
Beautiful view. Clearly unequal with nice angular distance. Primary component appeared in pale yellow, secondary component silvery-white.

4.5" f/8, 28x, Bortle 6, NELM 5.3, SQM-L 19.7
Well split with big difference in brightness.

STFA24 (**)

Name: STFA24
Type: **

Coordinates: 13h10m03.27s / +38°29'55.90"

Components:
m1 m2 ρ θ Year
AB 6m0 6m3 275.6" 296° 2012
This double star contains of the components 15 and 17 CVn.

B 40mm, 8x, Bortle 7, NELM 5.0, SQM-L 19.2
Both components similar in brightness with large distance.
