Comet M4 Swan now visible in binoculars
Comet M4 Swan is now visible in binoculars in the North West in early evening from around 20:00 BST. Look out for a fuzzy 6th magnitude "star". Currently between The Plough and Bootes, Heavens Above has a finder chart which is updated daily. I took this image, which is a total of 37 minutes exposure, Saturday night. Notice how the stars have trailed as I tracked the comet moving through the field of view. The height of this image is about 1/2 degree. I could not see the tail visually in 10x50 binoculars or the 80mm refractor, only in the image.
