B 8x40, Bortle 6, NELM 5m3, SQM-L 19.7
Appeared more roundish & evenly bright. Well seen with averted vision.

MODERATE
102mm f/11, 28x, Bortle 6, NELM 5m0+, SQM-L 19.3
At 28x bright, slightly oval. The fairly compact, almost stellar center is visible with averted vision. Otherwise the galaxy appears rather evenly bright. At 86x the center is more evident and appeared slightly elongated, whereas the very compact nucleus is most apparent.

4.5" f/8, 60x, Bortle 6, NELM 5m3, SQM-L 19.7
Bright, slightly oval center with oval, fainter halo.

EASY
152mm f/5.9, 22x, Bortle 6, NELM 5m0+, SQM-L 19.3
At 22x striking, bright, slightly oval. The brighter, compact center is visible with averted vision. At 129x the dust lane was also well visible to the northeast of the center with averted vision.

EASY
8" f/6, 37x, Bortle 4
At 37x very bright, nearly stellar core with oval halo. Orientation NW-SE. At 100x bright, stellar core. Galaxy seems mottled arround the core. At 171x northeast of the core an obvious, slightly curved dark area (= black eye).

B 10x50, SQM-L 21.5
die Black Eye Galaxy ist gut sichtbar innerhalb eines Trapezes, das aus 5 Sternen gebildet wird - sie ist hell und kompakt, im Zentrum sind Helligkeitsunterschiede wahrnehmbar

EASY
B 16x70, SQM-L 21.5
sehr hell und gut begrenzt erkennbar - OW-Elongation 2:1

EASY
B 18x70, SQM-L 21.5
eine diffuse, leicht unrunde Galaxie mit einem hellen kompakten Zentrum - SO-NW-Elongation

EASY
100mm f/6.4, 71x, SQM-L 21.5
bei 20x ist die Galaxie gut sichtbar innerhalb eines auffälligen Sterntrapezes - ihre Helligkeit steigt zur Mitte hin an - bei 32x wirkt M 64 leicht elongiert, das Zentrum scheint leicht nach Süden versetzt zu sein - bei 71x zeigt sich eine große helle diffuse Galaxie - unterhalb des Zentrums Richtung Südwest sind Unregelmäßigkeiten wahrnehmbar bzw. dort wirkt sie nicht so homogen

2020-04-04: Lovely sight! Beautifully separated with little difference in brightness. Together with two other brighter stars the double star forms an almost right-angled triangle. At 44x the primary component appears in pale orange, the companion rather grey-bluish.
