Imaging during EST to DST change over


Michael Freeberg
 

Jack,

If you go into the hand controller it gives you the option of setting it to utc.  I also   
have Dimension 4 installed on my laptop which keeps it synced to a UTC standard.

Right now I have the hand controller set to standard time and the computer likewise.  Rather than go through the procedure to set the hand controller to DST, can I just go into the keypad, set it to UTC, set the computer to UTS, and not have to do anything else?
 
Yours truly,

Subject: [ap-gto] Imaging during EST to DST change over

Last night I was imaging with my QSI683 camera through the AP 130EDF on my Mach1GTO and had an unusual thing happen. I was on my last subframe of the evening, at around 2am and suddenly I noticed that the guiding errors grew tremendously.
 
I noticed the guide star was out of the field so I grabbed an additional full frame exposure through the guide camera to see what had happened. A 5 sec exposure showed stars streaking in the field of view, like the tracking was incorrect or even off.
 
After closer inspection I noticed that the mount parked itself at exactly 2:00am when the PC's clock automatically advanced from 2:00am to 3:00am during the EST to DST transition. It wasn't too much of a problem since I was closing down for the night anyway, so I lost the 10 min subframe.
I was wondering why/how the mount automatically parked due to that sudden time shift Any ideas? Anyone else had this happen to them?

FYI we went through a time change in September (Chile) and our 1600 did not do anything unusual. It imaged the whole night and started up as expected the next day. I just had to review/adjust the start times for some targets

Internally, mounts operate on UTC time only and don't care about/know about silly constructs such as DST and time zones. I would pull the session's logs from whatever imaging or sequencing program you're using and APCC, if you're using that.

I've seen funny things with lots of programs over the years regarding their reaction to DST changes, the start of DST in particular. A typical scenario is a program monitors IO for timeouts based on local wall clock time, and not seconds elapsed. Suddenly time jumps forward 1 hour and the program is convinced that it hadn't heard anything for an hour, and reacts in an improper way.
