CCD Photometry with the network STACC

In an earlier Newsletter No. 5 we announced a new network project under the acronym STACC which is an attempt to join observers with small telescopes equipped with CCD cameras into teams that can produce light curves for variables (panicularly Delta Scuti stars) with very good window functions and very good signal to noise ratios. Here we would like to report on the results of the first campaign of this type where we only had two sites involved but still produced impressive rcsults. In May/June 1993 Luis Balona and Chris Koen observed with the 1m Sutherland telcscope from South Africa and Soren Frandsen and Michael Viskumwi h the Dutch 90cm telescope at La Silla. The principal target was the open cluster NGC6134 but in the beginning of the night we could also get a few hours of data on NGC 2660. NGC6134 was known to have Delta Scuti variables (five) and NGC 2660 was expected to have an equal amount of variables within the field of view.
