Wolfgang Reissenberger created a new topic ' Guiding remains suspended' in the forum. 13 minutes ago

I stepped into a problem last night where PHD2 remains suspended after focusing finished. The Guide module assumed PHD2 would be in state GUIDING while PHD2 remained suspended. Here is the extract from the logs:

[2020-04-09T01:04:27.017 CEST DEBG ][     org.kde.kstars.ekos.guide] - PHD2: request: "{\"id\":5783,\"jsonrpc\":\"2.0\",\"method\":\"set_paused\",\"params\":[true,\"full\"]}"

[2020-04-09T01:04:27.437 CEST INFO ][     org.kde.kstars.ekos.guide] - "Guiding resumed."

The critical point is at 01:04:27.436 where PHD2 reports a guiding step although it is suspended. This has the consequence that the EKOS guiding module thinks PHD2 is in the guiding mode and sets the step to GUIDING. Here is the code snippet:
void Guide::setAxisDelta(double ra, double de)
{
    //If PHD2 starts guiding because somebody pusted the button remotely, we want to set the state to guiding.
    //If guide pulses start coming in, it must be guiding.
    if(guiderType == GUIDE_PHD2 && state != GUIDE_GUIDING)
        setStatus(GUIDE_GUIDING);

As mentioned in the comments the intention behind this is that PHD2 has changed its state, but I think this assumption is at least too general. I personally tend to remove this statement, since from my point of view this is at least the wrong place to change the state.

Any thoughts about this?

As a workaround, I suggest avoiding to suspend guiding during focussing, until this problem is fixed.

Hi!

Hrm. you were right - wrong location. Although I am dead certain that's the first thing I checked... hrm. Anyway: now it looks better, will keep working and return if there is more to the issue.

Thanks.

I've been using the internal guider and it works for me. Not sure what PHD2 would offer over ad above the internal guider except for another app to keep an eye on.

Hello,

I'm new to ekos and the whole astrography. I wonder if someone can advise me which guider app is better to use with ekos, internal or PHD2?

I'm new to both but I have seen more videos about PHD2 and only one for the internal...

Thank you...

Aaron Glatzer replied to the topic 'Use Scheduler on-board Stellarmate?' in the forum. 7 hours 3 minutes ago

Thank you for your help.

Sorry, I guess I wasn't clear enough previously. I was doing just as you suggested: I did have profiles on my remote PC, and I had separate profiles on the Stellarmate. I tried to allow the Stellarmate to operate autonomously by connecting through VNC to set up its scheduler. However when I did so the profiles on the Stellarmate did not show on the Stellarmate scheduler profile drop-down, only "default profile".

However last night I tried again to make sure I had not done something wrong. This time it worked as expected: the profiles on the Stellarmate showed in the scheduler profile drop-down, and when I ran the scheduler it performed as expected.

I'm not sure what had gone wrong - perhaps the first time I tried something had not been properly initialized, perhaps I needed to reboot, I don't know. Any way it is working now!

Thank you again for your help.

No, there's no way to join two observation schedules in the Scheduler UI. This obviously lacks.

Most probably your geographical location is misconfigured. If you added a custom one, check the DST settings there.

Hi,

I also had this issue recently. I found a workaround which is to disable Time sync between Kstars/Ekos and Indi.
You will this setting in Configuration -> Kstars Configuration... -> INDI -> Time and Location Updates. There uncheck "Time".

Hi!

I've run into some time issues lately with the Scheduler. Today, my Kstars runs correctly on CET. But seems not to adjust for summer time. THis means that Kstars says time is 8 pm when "real" civil time is 9 pm. However, the twilight-dusk settings in Scheduler seems to be in civil time. That is, tonight I should be able to start imaging around 9.30 pm. Which is almost now. But Scheduler thinks that is more than an hour away - something I interpret as Scheduler running on Kstars time, which seems to be without summer time - but twilight time is WITH summer time correction.

Sorry if this sounds confused. I AM confused by these issues. Anyone recognize (not my confusion but the time issue)?

Jasem,
in profile editor I can't set QSI as filter. So there it's none. I sorted out the problem and removed the CCDSimulator as possible problem from the INDI server. So it should now be impossible to use it.

Giles replied to the topic 'HitecAstro DC Focus' in the forum. 12 hours 14 minutes ago

So I have done a calibration, and the initial results look like this in a Spreadsheet, based on a Out Focus speed set at 75



On my next outing, I will try the new driver, using the OutFocusFactor setting of 0.862 and a speed of 75

If I have any success with autofocus, then will see if there is a way to get this patch accepted into the INDI source tree.

Jasem Mutlaq replied to the topic 'False Filter Entry in FITS Header' in the forum. 15 hours 24 minutes ago

in Ekos, is QSI selected as the filter wheel as well? It appears to be the CCD Simulator filter wheel that is getting written.

Magnus Larsson replied to the topic 'Scheduler and variable stars' in the forum. 15 hours 48 minutes ago

Hi!

I am also experimenting to find good ways to work with variables in Ekos. And I'd like to follow up:

I have a saved scheduler job with 20 variables, that is, a saved list of 20 jobs. Now, I'd like to add ANOTHER list of say 5 jobs that I have saved in another scheduler file. What happens is that when I open a schdeuler file, it replaces the list of jobs already there - but I'd like to ADD to it, not replace it.

I understand that I can do this by manually editing the files, let's say, I open the second in a text editor, and copy the contents. THen I open the first list and past the whole second list there, last. And save under a new name.

But I'd like to do this in the scheduler. Is there a way to do this? So to speak to have the option "append to existing jobs OR replace existing jobs" when I open. Is that doable? Or a feature request?

Giles replied to the topic 'HitecAstro DC Focus' in the forum. 16 hours 21 minutes ago

So the way I will attempt to calibrate this is:

1. Position Telescope with Imaging train at 90 degrees, with telescope pointing to Zenith
2. Set settings to: Telescope Altitude = 90, Focus Factor = 1
3. Focus out 1000 steps, measure the distance the tube moves
4. Focus out 1000 steps, measure the distance the tube moves
5. Repeat until Focuser is near limit
6. Focus in 1000 steps, measure the distance the tube moves
7. Repeat until Focuser is back at start point
8. Repeat from Step 3 until we have a good sample.
9. Take averages of the Focus out distances, and averages of Focus in distances.

It may make sense to Focus in say 100 steps after changing direction, it might eliminate some gear backlash in the focuser.

The focus factor you should set would be focus_in_average / focus_out_average.

As I've mentioned I'm not getting the Telescope Altitude from the Active Telescope driver, so if you're going to be imaging something that moves from say 30-34 degrees in altitude then just set an average for that to say 32, or update the altitude as you go along.

Giles replied to the topic 'HitecAstro DC Focus' in the forum. 16 hours 32 minutes ago

I've fixed the maths used to calculate the reduction in Focus motor speed according to Telescope Altitude (as set in the Focuser Control Panel) and the out focus factor.

So now, it will actually set the speed to (Focus Factor) * (In Focus Speed) if the Telescope Altitude is set to 90

On trying to calibrate it before I almost dropped the focus tube with the imaging train to the floor (I've removed the old patch). So V2.2 of the patch should be the fixed version.
