Also visible is part of the H-Alpha cloud known as Barnard’s Loop which encircles the left-hand/East side of the constellation. Barely visible on following the line of the dark lane in the centre of M78…

The nebulosity was clearly visible from the outset in the fast Dobsonian and a 24mm eyepiece. With greater dark adaption the fainter nebula became visible and…
