The cluster around Sk-71 51
Small field around the hot star Sk-71 51 as seen through the V filter. The left image shows a single frame after subtraction of the nebular background. The image quality - or seeing - is roughly 8.5 pixels, corresponding to 0".72. The right panel shows the same field after applying a sophisticated image-sharpening software ("deconvolution"). The resulting resolution of the sources is 3 pixels, or 0".25 on the sky. This shows that the brightest object is in fact a very tight cluster, composed of 6 stars in an area 4 arcseconds wide. The field size is 21".7 x 21".7. North is up and east to the left.
