Hi,<br>
<br>
during recent imaging sessions with KStars/Ekos (running latest
Indi/KStars from git) I got the feeling that the time span between
exposures was shorter than it should be. I kept a close eye on
what's going on particularly between exposures and came away with
the impression that the "Only Start if Guide Deviation <" check
is performed before the first image in the queue (and the first
image after the re-start of an interrupted queue) but ignored for
all subsequent images.<br>
<br>
I spent some time on browsing through one of my logs for evidence. I
think it underpins my belief...<br>
<br>
I've linked the log file that I am referring to here: <a

<br>
I had interrupted a queue for a re-focus because HFR was
deteriorating. I finished focusing at 23:42:25 and the <u>first
capture</u> in the queue (after re-start) was about to be taken
but the guiding deviation check was performed and found 1.865"
exceeding the 0.5" limit thus suspending capture until 23:42:32 when
guiding deviation of 0.46" was lower than the limit. At 23:42:34 the
120s exposure was started. It finished at 23:44:34, saved a second
later. Then there is a 24s pause in the log file. I suppose during
this time FitsViewer displayed the image and calculated HFR.<br>
<br>
Dithering started at 23:44:59 and was completed 10s later at
23:45:09. This time (<u>second capture</u> in the queue after
re-start) no "Only Start if Guide Deviation <" check is
mentioned. Instead, "resuming in 8s" (as set up in "Ekos ->
Capture -> Guiding settle"). After these 8s, at 23:45:17, a focus
check is performed. It finishes at 23:45:22 and the next exposure is
started right away, at 23:45:22. Still no guide deviation check
mentioned.<br>
<br>
I believe (but cannot prove it) that I witnessed several instances
during the night where after dithering had succeeded, the next
exposure was started although guiding deviation was around 2", way
above the limit.<br>
<br>
Maybe someone can have a look into this. Thanks a lot!<br>
<br>
