Scheduled refocus failing #51357
Hello !

I recently updated kstars to the latest version (Build: 2020-02-23T18:06:07Z) in order to get the new features (the new focus algorithm is great!! Thanks!).

However, since then, I am experiencing issues when a scheduled refocus is triggered.
The issue is present for all scheduled refocus (but the filter change focus still works like a charm).

I attach the logs in this post. Here is what happens:

1. After some images are captured, a scheduled refocus is triggered:
<code>[2020-03-28T20:44:02.838 CET INFO ][ org.kde.kstars.ekos.capture] - "Scheduled refocus starting after 1821 seconds..."
[2020-03-28T20:44:02.840 CET DEBG ][ org.kde.kstars.ekos.focus] - Frame is reset. X: 0 Y: 0 W: 3354 H: 2529 binX: 1 binY: 1
[2020-03-28T20:44:02.841 CET DEBG ][ org.kde.kstars.ekos.capture] - Capture is triggering autofocus on line 1904.
[2020-03-28T20:44:02.841 CET DEBG ][ org.kde.kstars.ekos.focus] - Check Focus requested with minimum required HFR 0.1
[2020-03-28T20:44:02.842 CET INFO ][ org.kde.kstars.ekos.focus] - "Capturing image..."</code>

I am a bit surprised the log says bin1, although bin2 is selected in the focus module. Also note I did not specify a minimum HFR.

2. An image is being taken by the camera, but guiding was not paused!
<code>[2020-03-28T20:44:06.233 CET DEBG ][ org.kde.kstars.ekos.guide] - PHD2: event: "{\"Event\":\"GuideStep\",\"Timestamp\":1585424646.232,\"Host\":\"florian-U36SD\",\"Inst\":1,\"Frame\":481,\"Time\":1804.307,\"Mount\":\"On Camera\",\"dx\":0.644,\"dy\":-0.172,\"RADistanceRaw\":0.658,\"DECDistanceRaw\":-0.032,\"RADistanceGuide\":0.428,\"DECDistanceGuide\":0.000,\"RADuration\":97,\"RADirection\":\"West\",\"StarMass\":5160,\"SNR\":32.52,\"HFD\":3.07,\"AvgDist\":0.52}\r\n"

3. The image is downloaded:
<code>[2020-03-28T20:44:08.005 CET DEBG ][ org.kde.kstars.indi] - Atik 383L : "[DEBUG] Uploading file. Ext: fits, Size: 4248000, sendImage? Yes, saveImage? No "

4. Nothing happens. Guiding is still on-going, the scheduler still waits for the focus to finish.
After a few minutes, I decide to click the Autofocus button in the focus module.
This time, the focus procedure is working fine, guiding is paused, focus is done, and sequence is resumed:

<code>[2020-03-28T20:46:46.176 CET DEBG ][ org.kde.kstars.ekos.focus] - Starting focus with box size: 208 Subframe: no Autostar: yes Full frame: no [ 0 %, 100 %] Step Size: 150 Threshold: 150 Tolerance: 5 Frames: 1 Maximum Travel: 50000

[2020-03-28T20:46:46.212 CET DEBG ][ org.kde.kstars.ekos.capture] - Guiding state changed from "Guiding" to "Suspended"

The issue occurs for all scheduled refocus, tested on 2 different nights. There must be a regression here.

Could you please have a look?

Thank you!

Scheduled refocus failing #51358
I have experienced scheduled refocus issues as well lately. In my case the last focus image of the PREVIOUS refocus was used for all focus images, leading to a flat curve all with exactly the same number of stars and HFR values. But the focuser moves so after the auto-focus fails, imaging is resumed with an out-of-focus camera. During focusing, guiding is suspended but the guide cam keeps on taking pics. Not sure if that is the expected behavior.

Here are the logs from a few weeks ago. Note for instance the last values of the second refocus attempt and all values of the third.
