The Butterfly nebula in Orion

Clear last night (although with a nearly full Moon) and managed to get a very seldom imaged iridescent reflection nebula appropriately named “The Butterfly nebula” in Orion. O.K. it’s a picture of the Morpho Rhetenor butterfly wing (structural colour) but … Continue reading
