* Black & White Images of Omega Centauri (NGC5139) and NGC5128
were obtained between 5:30 and 6:00am on 17 January 1999 as each
object culminated low on the southern horizon. The image of
NGC5128 consists of nine 90sec exposures added together. The
image of Omega Centauri consists of five 15sec exposures added
together. The LX-200 telescope computer controls would not move
the telescope to Omega Centauri, because the object&##39;s low
position on the southern horizon triggered the limit switch on
the telescope designed to prevent the telescope optical tube
from striking the base of the telescope mount. Fortunately,
Omega Centauri was visible through the telescope&##39;s finder, and
the telescope was manually centered on the object for CCD
imaging. These images were purposely obtained in the early
morning, because the light pollution from Tucson is less than in
the evening, and the sky is steadier. The observatory sits
approximately 6 miles directly north of the center of Tucson.

**The color image of NGC5128 was obtained at 11:30pm on 28 April
2001 as the object culminated low on the southern horizon. It
was imaged with the object sitting in the sky just above my
house and the city lights of Tucson. This image consists of
three 60sec red (R), three 60sec green (V), and five 60sec blue
(B) images combined into a final color image.
