STF948 (**)

Name:	STF948, 12 Lyn
Type:	**
Constellation:	Lyn
Coordinates:	06h46m14.15s / +59°26'30.10"

Components:
		m₁	m₂	ρ	θ	Year
	AB	5m4	6m0	1.9"	66°	2018
	AC	5m4	7m0	8.8"	310°	2018

55mm f/9.1, 167x AB: Components A and B separated, whereby the Airy disks slightly overlap. The difference in brightness was well visible.
55mm f/9.1, 27x AC: Components A/B and C well separated, but tight. Significant difference in brightness. The fainter C companion appeared slightly orange, the brighter one white-bluish.
63mm f/13.3, 140x AB: Components A and B split with almost no space in between. The difference in brightness was visible.
70mm f/5.7, 133x AB: Both components A + B clearly split, whereby the diffraction rings where merged together. A very nice view together with component C. I sketched this triplet, which reflects my impression well. Unfortunately, the distance and position angle are not particularly well observed. Also the difference in brightness I didn't noticed during my observation.
70mm f/5.7, 22x AC: Well split, relatively close together with significant difference in brightness.

STF958 (**)

		m₁	m₂	ρ	θ	Year
	AB	6m3	6m3	4.5"	77°	2018

70mm f/5.7, 33x
Clearly split, equally bright, close together. Nice view.

STF1009 (**)

Name:	STF1009
Type:	**
Constellation:	Lyn
Coordinates:	07h05m39.83s / +52°45'31.30"

Components:
		m₁	m₂	ρ	θ	Year
	AB	6m9	7m0	4.4"	149°	2018

70mm f/5.7, 33x
Very nice view. Equally bright components, tight.

STF1050 (**)

Name:	STF1050
Type:	**
Constellation:	Lyn
Coordinates:	07h19m51.29s / +54°55'18.40"

Components:
		m₁	m₂	ρ	θ	Year
	AB	8m1	8m8	19.3"	21°	2017

70mm f/5.7, 22x
Rather faint, obviously split with visible difference in brightness. View similar to STF 1062.

STF1062 (**)

Name:	STF1062, 19 Lyn
Type:	**
Constellation:	Lyn
Coordinates:	07h22m52.06s / +55°16'53.30"

Components:
		m₁	m₂	ρ	θ	Year
	AB	5m8	6m7	14.8"	316°	2018

70mm f/5.7, 22x
Clearly separated, moderate distance, noticeable difference in brightness. The colors seemed different, but not exactly definable.

STF1065 (**)

Name:	STF1065, 20 Lyn
Type:	**
Constellation:	Lyn
Coordinates:	07h22m15.11s / +50°08'55.70"

Components:
	m₁	m₂	ρ	θ	Year
	7m5	7m7	14.9"	256°	2017

70mm f/5.7, 22x
Nicely split, moderate distance, similarly bright.

STF1282 (**)

Name:	STF1282
Type:	**
Constellation:	Lyn
Coordinates:	08h50m44.28s / +35°04'15.40"

Components:
		m₁	m₂	ρ	θ	Year
	AB	7m6	7m8	3.5"	280°	2018

70mm f/5.7, 57x, Bortle 6, SQM-L 19.4
Clearly separated, but close together with very little difference in brightness. The double star forms an acute-angled triangle together with two other stars.

STF1289 (**)

Name:	STF1289
Type:	**
Constellation:	Lyn
Coordinates:	08h54m44.33s / +43°35'04.70"

Components:
	m₁	m₂	ρ	θ	Year
	8m2	8m9	3.6"	8°	2018

70mm f/5.7, 57x, Bortle 6, SQM-L 19.4
Quite faint double star, but easy to separate with a noticeable difference in brightness and close components.

STF1333 (**)

Name:	STF1333
Type:	**
Constellation:	Lyn
Coordinates:	09h18m25.97s / +35°21'51.30"

Components:
	m₁	m₂	ρ	θ	Year
	6m6	6m7	1.9"	50°	2017

63mm f/13.3, 120x
At 93x seen as '8', at 120x split, but pretty tight with no visible difference in brightness.

STF1334 (**)

Name:	STF1334, 38 Lyn
Type:	**
Constellation:	Lyn
Coordinates:	09h18m50.64s / +36°48'09.30"

		m₁	m₂	ρ	θ	Year
	AB	3m9	6m1	2.5"	229°	2017

63mm f/13.3, 140x
Fainter companion only seen as permanent brightening on the first diffraction ring.

STT174 (**)

Name:	STT174
Type:	**
Constellation:	Lyn
Coordinates:	07h35m56.00s / +43°01'51.40"

	m₁	m₂	ρ	θ	Year
	6m6	8m3	1.9"	92°	2017

70mm f/5.7, 133x
The obviously fainter component could be permanently seen in the right position angle as brightening on the first diffraction ring.
