I think that meridian flip should be initiated using true telescope coordinates, or alignment could be disabled when performing the flip.
In any case I would suggest you use more alignment points, the nearest model is quite simplistic.


How would clients know about true telescope coordinates? From Ekos, I just monitor HA and issue GOTO to the same place once HA threshold is exceeded.

indi-eqmod exposes true telescope coordinates in the align tab, and maybe every mount should expose them. Ekos monitors HA using aligned coordinates, and as said above, initiates the flip when HA is 0.06 above meridian. In the log the alignment process (be it Nearest or Nstar) reports a 0.08 difference in RA, thus the goto won't perform a flip. This is a feature, not a bug. Actually you may now use the Pier Side property as defined by Patrick (which uses true coordinates in the driver directly) to initiate the flip: there you will be sure the mount would perform a flip.
The other point was tthe number of sync points: using only one sync point is not very useful. And if you make your sync near the pole, a small error here is multipled by the inverse of the sinus of the declination. I wonder if this is not why some people get scope outside limts error sometimes.

Ok, part 1 logs with Canon drivers. Mirror lockup is enabled.
Key Events:
~T00:47:57 Capture preview image - success
Enable Live View onboard camera
~T00:48:56 Capture new preview image - Camera shutter actions twice, single frame downloads
Disable Live View, Note blinking available image count, indicating attempt to write image to file.
~T00:51:29 Capture another preview. w/o live view. Image downloads. Counter still blinks.
Re Enable Live View
~T00:54:09 Capture image, shutter actions twice, no image downloads, camera gets stuck on BUSY. After some time INDI driver enters a cycle of failures until Stop Sequence is pressed.

Next: power off Camera; camera attempts to record images from memory to file.
Pull USB allows camera to turn off and back on again.
~T01:00:32 Camera will not reconnect.
Hard power cycle of camera, and reconnecting USB in various fashions does not resolve this state.
I have only managed to clear it up by rebooting.
Also pulling power to the camera resets the RPi3 USB controller, all connected devices are dropped. EQMod Mount disconnects and it's comm port has to be changed tom ttyUSB0 to ttyUSB1)

Deduction on camera Live View interferes with Mirror Lockup. Incidentally other problems arise if the Live Video stream is enabled while an image is taken. The image coming in blank is not totally accurate, I think it was just a much shorter exposure taken with the mirror lockup trigger.

Andrew replied to the topic 'KStars 2.7.6 is release' in the forum. 6 hours 36 minutes ago

So I noticed something I missed while making this with the CCD simulator, and is the source of my confusion. I just realized that the solved frame is relative to the Equatorial coordinate grid while the FOV Symbol is relative to the Horizontal Grid system, obvious to me now why they won't match. Last night I was trying to use the FOV symbol as a reference to frame the Markarian chain and was not getting the framing I was expecting based on the value of the angles.
Terribly sorry this doesn't belong here after all.

I have to work out how to make the more in depth logs and attempt to reproduce the problem.

Thanks for report, problem fixed in GIT. Should hopefully appear in the PPA tomorrow.

Stephen replied to the topic 'Ekos, INDI, SkySafari, and NexStar' in the forum. 9 hours 15 minutes ago

Update:

- Nexstar+ for CGEM version 5.29.6225
- Kstars' INDI settings rechecked, it was set to computer update device. Reviewing this now considering the above.
- there were logs and since the RPI3 was not connected to a network it was set to July 2018. As soon as INDI was started this time was sent to CGEM. So all is working and it was my miss in a setup.
- It seems the start and connection of the INDI server is when the INDI updates the Mount. So connection is acceptable as long as computer (RPI3) has time set correctly before starting INDI.
- Considering web page to sync iOS time with computer and then push to CGEM. Not attempting Computer updating the Long/Lat.

If the CGEM is aligned with with time and location via HC, then changed by computer, does an alignment need to be done again?

e.g. CGEM date/long/lat set to "now" and actually locations. Then Kstars updates it due to user error to wrong time and location, such as a year in future and another contintent. Can the computer time location be changed back and resent to CGEM, and all be right again without having to do another alignment since the time/location were correct, changed, and then made correct again?

Ah mount log! With log comes possible solution. So it appears that your slew accuracy for RA is too low. It's probably set at default 3 arcmin? Set it to 11 or 12

Hi!

This is something of a return issue - I've had something similar a few months ago. What happens is that I slew to a target, but there seems to be no "slew finshed" signal. THis means I cannot capture, and the align process waits forever. In reality, the slew is completed long ago, but Ekos keeps waiting. It's a Losmandy G-11, Gemini 1. Any idea what is going on here? Mount log attached.

I'll check what my settings are, it could ofcourse be some comms issue, though I doubt that with the Ethernet connection. Or the mount itself has a problem. Thanks for checking!

Hi Jasem,

When I playback a 30-frame clip that I recorded with V4L2 using SER Player, I see the following information (see attachment). The time is correct but the date is not. It should read "26/03/2017" not "26/02/0117".

Thank you.

Jean-Luc replied to the topic 'Meridian flip still working for people?' in the forum. 12 hours 7 minutes ago

Hi,
Concerning the log you gave above, all what I can say is:

  • you made a single point alignment, I suppose when you start your session, maybe 1h30 from the meridian, or near the pole, or else you check the Align Nearest mode
  • anyway, the delta_ra is 0.08, the meridian flip occurs at 0.06, so I think the goto, after alignment, does not perform a flip
I think that meridian flip should be initiated using true telescope coordinates, or alignment could be disabled when performing the flip.
In any case I would suggest you use more alignment points, the nearest model is quite simplistic.

Jean-Luc.

If you record video SER frames then you get that kind of resolution with INDI already

I don't have the experience needed with indi at the moment to develop driver. But scripts are nice and easy to write, so the scripting gateway seems like a great driver to use. But do you think it will work with a roll off roof?
