This wide field image shows a big bow of galaxies in Leo, containing 3 Messier objects (M95, M96 (barred spirals at right), and M105 (elliptical, bottom center), plus a larger number of fainter galaxies (including NGCs 3367, 3377, 3384, 3412 as well as UGC 5889 and UGC 5832.
The spiral galaxy NGC 3338 and the Sc galaxy NGC 3389, which are in the same field are background galaxies at approx 50-60 million light years distance, whereas the members of the Leo I group are approx 30-40 million light years distant.
105mm TMB refractor with flattener at f/6.5
About this Image
