55mm f/9.1, 90x, Bortle 6, NELM 5m0+, SQM-L 19.3

FAILED
70mm f/5.7, 72x, Bortle 6, NELM 5m0+, SQM-L 19.3
Almost held with averted vision, oval to slightly elongated, faint, evenly bright.

DIFFICULT
152mm f/5.9, 100x, Bortle 6, SQM-L 19.4, Seeing 3/5
Obvious with averted vision, noticeably elongated, moderately condensed.

MODERATE
8" f/6, 100x, Bortle 6, SQM-L 19.3
Evident with averted vision, slightly elongated, evenly bright.

MODERATE
8" f/6, 100x, Bortle 4
Already seen at 37x as slightly elongated nebula with averted vision. At 100x elongated, a bit brighter core, otherwise evenly bright, seen with direct vision. Nearby the great globular cluster M13!

EASY

bei 49x kann indirekt eine kleine schwache Aufhellung gehalten werden - sie ist leicht länglich NO-SW-elongiert - bei 71x ist die Galaxie indirekt noch deutlicher sichtbar - im Süden wirkt sie leicht heller

MODERATE
8" f/4, 85x, SQM-L 21.5
bei 40x als länglicher Nebel erkennbar - leichte Helligkeitszunahme zur Mitte hin - bei 85x wird die Galaxie noch deutlicher mit diffusen Außenrändern sichtbar - nach wie vor nur leichte Elongation erkennbar

EASY
12.5" f/4.5, 160x, SQM-L 21.5
bei 72x zeigt sich die Galaxie mit einer Elongation von 3:1 - bei 160x wird indirekt eine stellare Aufhellung sichtbar
EASY

After a longer, concentrated observation, a permanent brightening of the first diffraction ring of the primary component could be seen at the correct position angle. The brightening appeared only arch-shaped without any noticeable condensation.

102mm f/11, 224x
Faint companion as distinct brightening on the first diffraction ring visible. In steadier moments visible as small, round condensation.

Already at 28x the components A, B and C were noticeable at first view. At 86x, component D could also be observed very well. The components are all comparatively far apart.

Easy. Pretty wide apart with large difference in brightness.
