4.5" f/8, 100x, Bortle 7, NELM 4m.5
Glimpsed with averted vision as very faint, round brightening after several minutes of concentrated observation. Forms a line with two brighter stars.

DIFFICULT

120mm f/5, 67x, Bortle 6, SQM-L 19.3
At 33x pretty faint, even at 67x not very conspicuous, round, moderately condensed.
|
MODERATE
|
8" f/6, 37x, Bortle 4
Round, brightening toward the middle. Neither resolvable nor granulous even at 80x. Barely visible with direct vision.

der KS zeigt sich bei 45x als zarter Schimmer - bei 72x wird ein homogen helles Bällchen mit diffusen Rändern sichtbar, das einer Galaxie sehr ähnelt - indirekt wirkt der KS fluffiger - bei 160x wirkt der KS noch immer recht hell - auch bei 240x sind keine Sterne herauslösbar

102mm f/11, 62x, Bortle 6-, SQM-L 19.0
At 28x already relatively well visible as clearly elongated nebula with averted vision. At 62x almost conspicuous, beautifully elongated, getting slightly brighter towards the middle, but without a distinct nucleus.

EASY
|
8" f/6, 37x, Bortle 4
With averted vision very elongated, otherwise only the brighter core area is obvious.

die Galaxie ist nördlich von einem schönen Sternfeld erkennbar - auffällig NO-SW-elongiert - ein homogen heller schmaler Strich - Ausdehnung 3:1

76mm f/7.5, 57x, SQM-L 18.8
bei 57x ist die Galaxie als schwacher Schimmer zu erkennen - deutlich länglich und gut definiert
|
MODERATE
|
12.5" f/4.5, 144x, SQM-L 21.3
bei 45x phantastischer Anblick, ein heller Lichtbarren mit 4:1-Ausdehnung - das Zentrum ist leicht heller - nordöstlich an der Galaxie klebt ein Feldstern - bei 72x verjüngen sich die Spitzen der Galaxie, längliches Zentrum - bei 144x blinkt indirekt am nordöstlichen Ende der Galaxie ein noch schwächerer Vordergrundstern auf - NGC 2683 wirkt leicht durchgebogen nach Südosten

Easy to split with noticeable difference in brightness. Very nice view together with the triple system STF 948 in one field of view!
|
|
152mm f/5.9, 100x, Bortle 6, SQM-L 19.4
At 100x and 129x easy to separate, quite uneven. Primary component appeared yellowish, the fainter one rather greyish. Fantastic view together with 12 Lyn (STF 948) in one field of view!

102mm f/11, 129x, Bortle 6-, SQM-L 19.0
At 28x the pair AC is nicely separated without any problems. The close pair AB is already recognizable at 86x as a clear figure '8', at 125x wonderfully separated. The components A & B appear yellowish. Very nice view together with STF 946 in one field of view!
|
|
152mm f/5.9, 129x, Bortle 6, SQM-L 19.4
At 49x the pair AC is beautifully separated with a significant difference in brightness. At 100x, the close pair AB is also separated, although still very close together. A slight difference in brightness is noticeable. At 129x, the view is magnificent. The two bright components A & B present themselves yellowish, the fainter component C rather greyish. STF 948 can be well observed in a field of view with the neighbouring double star STF 946. Both show a nice overall scenery.
|
|
55mm f/9.1, 167x
AB: Components A and B separated, whereby the Airy disks slightly overlap. The difference in brightness was well visible.
|
|
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.
|
|
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.
|

70mm f/5.7, 22x
AC: Well split, relatively close together with significant difference in brightness.

2020-03-23: At 28x the pair A-BC is easy to separate. At 160x, the very close pair BC shows split. The component A appears slightly orange.
|
|
152mm f/5.9, 129x, Bortle 6, SQM-L 19.4
2020-03-23: At 22x, the wide pair A-BC already appears separated, but still very tight. At 69x, A appears in a subtle orange. The pair BC shows elongated and rather greenish-bluish. At 100x BC is already visible as figure '8' and almost separated, at 129x clearly separated. Components B and C are still very close together and equally bright. The color impression remains. An interesting and rewarding triple system!
