M83 has an angular size of 12 x 10 arcminutes and has very high
surface brightness. It is easily found in even small scopes
and is located in the southern hemisphere at a declination of -30
degrees. The high surface brightness is due to a very high star
formation rate. Galaxies which have high star formation rates
generally have strong spiral structure and M83 is an excellent
example of this. This is a blue band imaged acquired remotely
by using the array controller (ARCON) and a Textronix 2048x2048
CCD device on the CTIO 1-m telescope. The observations were done
in Eugene Oregon through the Internet. The image was acquired on
the night of August 18th. It appeared on this WWW site on August
19 to serve as an example of the rapid dissemination and delivery
of scientific data to the public at large.
