Thanks. The Force re-alignment before starting each job in the EKOS settings for the mount is set but no plate solve is happening on flip.

I can't find a setting for this.

Actually I just realized that I can put any string in the Name field in the scheduler so this will get me what I need. I just add it to the target name.

Is there a way to include a string in the file name that can serve as a Pixinsight WBPP session tag. Right now I use a batch renamer to add a string "_SESSION_Jan-1--2022" to each file?

Thanks

The problem is back. Last night I commanded a go to to IC 405 and the mount stopped several degrees away and refused to converge after several repeats. I got out of my recliner and went to the mount and commanded using the hand controller and the mount went right there. Tonight was the same story however it converged after 6 or so repoints.

Yes but I can’t say 100% why as I did 3 things. I increased the exposure to 60 seconds. I found an issue with focusing and found a better initial condition. And I deleted the Kstars directory that stores all the program information and reinstalled Kstars. If I had to guess I would say the improved focus and exposure was the root cause. The online solver seems to be less sensitive to focus.

Thanks Jerry!

I am running on a Mac Do you know where the log files are kept. The I click on the open logs directory in this tab it does nothing that I can see.

I get this error message:

Please check you have sufficient stars in the image, the indicated FOV is correct, and the necessary index files are installed. Enable Alignment Logging in Setup Tab -> Logs to get detailed information on the failure.

Does anybody know where I find the " Setup Tab -> Logs to get detailed information on the failure."

It works if I use the external Astrometry.net solver.

Thanks

The align module no longer can find any stars. This has been working for 9 months and now it quit. The exposure and ISO are the same for the align module and focus and camera module. The camera collects and shows and HFR of 2.57. The Focus module shows an HFR of of 1.3. I reset the align module to the defaults but this did nothing for the problem.


Thanks

Last night I opened the RA and checked all the cables on the CEM70EC. Everything looks fine so I did a goto to  using Kstars and also using the hand controller. The image below is the result of the hand controller goto command.  I also verified the time on the mount agreed with the time on the computer and Kstars. The polar alignment was within 1 arc-minute. You can see in the image below where the mount is pointed and the aim point is E Aquilae  I did a seek zero with the hand controller after the polar alignment and also tried the encoder calibration that was in the iCommander window. The FOV is about a degree so you can see the the mount is 3-4 degrees off of the aim point. I dis a solve and the plate solver found a couple of hundred arc-sec error which it was happy to correct however this converged on the current position of the mount and not on the target that was put in via the had controller. Sending an additional goto command with Kstars resulted in a telescope move to E Aquilae and the subsequent plate solves place the star in the center of the FOV. I did other points during the night and they all missed but. came close. In each case a second command resulted in convergence. At each point a plate solve converged on the actual mount position and not the target. My uneducated guess is that the EKOS software is getting the desired position from the CEM70 and that this position is representative of the actual pointing position of the CEM70EC  but not that of the desired target. Does anyone know if this is where Kstars is getting the location for the solver?. I was running the latest Kstars 3.5.5.2 as I recall.

Thanks for your suggestion. As near as I can tell the CEM70EC uses J2000. Do you know where I set this in Kstars/EKOS? I've searched some but cannot find it.

The Mount is an iOptron CEM70EC using the CEM70 driver. I guess I am most surprised that the plate solve solves to the wrong location and closes to less than 30". That would seem funny if the mount couldn't move in RA. I will add my equipment again.

I have a problem that showed up and I suspect my Mount. When commanding a slew to a target the bullseye representing the mount position stops short of the target that is centered and tracked in Kstars. Repeating the command to position the mount causes a motion in Dec only parallel to the target but the RA error does not get reduced. If I do a plate solve with slew and sync the Mount converges not on the target but on the position of the mount as indicated in Kstars.

One question I have is that when you do a plate solve where does EKOS get the desired pointing location from? If it is reading the mount for the desired location then the behavior of the plate solve makes sense.

If the time was wrong then I could understand a fixed error in RA however the Dec moves up and down to either side of the target alternating sides with each point command. If it were a time error the mount shouldn’t move after the initial point.
