Steve's Notes

===== NGC 884 18" (8/11/10): NGC 884 includes three rare M-type red supergiants including two mag 8/8.5 colored stars separated by 1.9' on the NE side of the cluster appearing red and warm yellow (V403 and V439). On the east side of the core of the cluster is the orange M-supergiant RS Per. 17.5" (10/25/97): the following group of the remarkable field of the "double cluster" is not as large or bright as NGC 869, but is centered around two wide triple stars. The central 5' has up to 50 stars including a number of faint mag 14-15 stars forming a rich background. Off the west end of the central region is a long string of stars which heads NE for 10' towards 3 brighter stars and then turning south and heading back past mag 8 orange-red RS Persei. The 20' field includes ~200 stars, although the field does include as many bright stars or as compressed as NGC 869. 8": this is the eastern component of the "double cluster". Very bright, large, very rich, ~20' diameter, ~60 stars, includes bright colored stars, many doubles.
