[APML] st-4 acting up

["Bobby Middleton" <bobm@koyote.com>]

It looks like my st-4 is needing several dark frames to settle down where it
can make true readings. This is after a 30 min+ start-up. It's warm here in
TX (90 deg at sundown) if that has anything to do with it. It's never been a
problem before during the heat.
Anybody seen this behavior and can you tell me what's going on?
I had this problem the other night and finally got it settled down where it
worked OK all night. I took 3-4 dark frames tonight beforte it settled down
to good readings.
