Photographed with the Moon at first quarter at precisely the day/time that this transient effect is visible. I was looking along the terminator and attempting to identify some of the prominent craters when all of a sudden this jumped out at me. I swear that if I had tried to find it it would have taken hours! The effect is actually only visible for approx four hours or so on one day a month when the Moon is at first quarter (lunar day 6.9). The next date it is visible is the 17th March by my…

Barely visible on following the line of the dark lane in the centre of M78…

The lack of Moon was a bonus and once the heat haze from the chimneys was no longer making the seeing even worse, I spent a fabulous hour observing Jupiter, the Pleiades, the Hyades and finishing with M42. 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…
