Steve's Notes

===== NGC 4103 13.1" (2/20/04 - Costa Rica): at 105x, ~60 stars mag 9.5-13 are resolved in a 8' region including roughly ten mag 10 stars. The cluster has a very interesting asymmetric arrangement with a perfect 5' string of five stars extending out of the cluster to the WSW. Two other short strings on the following end meet up and make a perfect arrow asterism. Located 12' ESE of mag 6.6 HD 104971. Located two degrees WSW of mag 3.6 Epsilon Crucis.
