Consisting of 4 interacting galaxies NGC6845 (ABCD) this small galaxy-group in the constellation of Telescopium resembles a little bit to the famous northern group of Stephan´s Quintett.
Occupying an sky-area of 4´x 2´ arc-min. and beeing not brighter than 13mag visually,the largest member of this quartett is the barred spiral galaxy NGC6845A,typed SBb.The real distance of
these galaxies could be determined to some 280mio.light-years.
2008 there happened the supernova-event SN2008DA.
NGC6845 was first seen by John Herschel in 1834.
