600/800mm - 24" (4/4/08 - Magellan Observatory, Australia): at 200x appeared moderately bright, fairly small, elongated NW-SE, 0.8'x0.5'. Sharply concentrated with a very small bright nucleus. The major axis is collinear with a double star (plotted as a single on Megastar) 3.5' NW. Located 38' NW of NGC 5833 in a small group.
