This is red Mars passing below the blue Pleiades star cluster (aka M45 and the Seven Sisters) on the evening of March 3, 2021. Taken on a night with some high cloud and haze adding the natural glows around Mars and the bright stars, accentuating their colours. This is a stack of 10 x 30-second tracked exposures with the Canon 200mm lens at f/2.8 and the Canon 6D MkII at ISO 1600, the Star Adventurer 2i tracker. Taken from home. The frame is cropped in to improve the composition and cut out some gradients.
