bei 131x ist die Galaxie indirekt als zarte Aufhellung sichtbar - bei 160x blitzt der Kern mitunter etwas heller hervor

bei 85x ist die Galaxie als schwaches diffuses Nebelchen zu erkennen - bei 160x ist sie dann eindeutig sichtbar - der Kern ist leicht aufgehellt - die Galaxie bildet mit zwei schwächeren Sternen ein flaches gleichschenkliges Dreieck
