Image Melting




Telescope CTIO 4m
Date 5/20/1998
Instrument BTC new chip 1
Filter R
Exposure
Time

480 s

Problem:

This star streaking phenomemon occurs only with the new chip 1 of the BTC. When the sky level is so high that it approaches the saturation limit of the detector, some charge transfer problem seems to set in.

Fix:

No fix possible, except for reducing the sky level (e.g., by reducing the exposure time).
