One correction, when I did the time test, the exposure time was twice what it should
have been. In your case, it looks like this is not the case. If in fact the two
images have exposure times of 240 seconds and on dark subtraction the resulting
image has exposure time 512.02, then could you send me the two images via private
e-mail for testing.



Thanks,
Ralph Pass
