The Jewel Box was terrible from Bangalore North as the South is completely light-polluted. I could see about 7-8 bright stars.

Even though the seeing was poor (mainly due to the full moon), the Jewel Box was quite spectacular, like its name suggests -- a tight collection of bright points. I had to use averted vision to see anything other than a faint blob but, when using this technique, it jumped right off the background sky at me. I think I saw a couple of red points amongs the predominantly blue-white points. Very impressive.

First night out with my first "new" second hand scope brought some of the loveliest sights around. Kappa Crucis ("Jewell Box") next to Beta Crucis showed the most beautiful arrangement of 15 blueish-white stars around a central red star in this open cluster, suitably described by Herschel Jr. as the most beautiful open cluster in the sky. A fitting opening night for my observing career!
