The small constellation of Sagitta the Arrow framed here with a field of view similar to binoculars, and showing the prominent star cluster M71 at centre. This is a stack of 14 x 6-minute exposures with the SharpStar 61mm EDPH apo refractor, with its flattener/reducer lens for and with the stock Canon R6 camera at ISO 800. Guided with the MGEN3 autoguider with dithering on but no LENR or dark frames to eliminate thermal noise or edge amp glows.
