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.

I used a RPI 4 with 8gb and both Astroberry and StellarMate for awhile. I now use a Mac Mini 2018 model. It has 4 TB ports and 2 USB and HDMI if you wish but I use RealVNC. It has great WiFi and I use a 4TB M2 pcie drive for images. I have run Ubuntu under Parallels on it too but running native on the Mini is easier. It is much faster than the RPI but cost $499 new when I got it in July.

There is a pop-up menu that asks for a one-time input of FPA size and pixel pitch. Where do I find where to change this. When I download an image from my Sony A7R4 I can find 3 different image sizes in EKOS/INDI. Furthermore if I store a file in FITS format it is of a different size tha the camera raw file. I inputted the wrong choice and INID is complaining telling me to purge the configuration and re-enter it.

Thanks

I am interested in a direct drive mount like the L-300. Is there any chance for a driver for this or the Alcor - DirectDrive Nova 120 Mount?

Thanks

Found the problem. I had increased size the INDI Server Transfer Buffer. Setting it back to 1024 fixed the problem.

My problem is back. I was running kstars 3.5.4 on OSX on an Intel Mac Mini and I installed 3.5.5 and then when launching EKOS and starting the configuration I get this error. I reloaded 2.5.4 and I have the same problem. I rebooted the Mac but tis didn't fix the problem.

Thanks

I found your post here very interesting. Thanks for sharing. I live in North Albuquerque Acres at 5850ft which is Bortle Class 5 so I am probably near your location. Looks like maybe you are in Edgewood. I just got my PlaneWave CDK 12.5 two days ago and set it up on my CEM70EC.

 

 

I am thinking that it might be too much for the CEM70 and as I was expecting the scope is not really suitable for a portable setup. This leads me to  think I need a dome and a new mount. So I had a couple of questions that you might be able to give me some guidance on. Right now I am running Kstars on a Mac Mini at the mount which works well. My first question is how well does your dome automation work? I am assuming you bought the stock 2.2M rotation and shutter automation kit.

My second question is regarding your CEM120EC2. My CEM70EC has gotten some pretty good performance if I am careful in the polar alignment. I have found that the iPolar scope in the CEM70 is off by about 4 arc-minutes but I can get unguided exposures of 5 to 10 minutes at 454mm focal length. I have been using PHD2 for most of my guiding.
 

So I am wondering if you have anything to share on the unguided or guided performance of your setup. If I use my 0.66 reducer there isn't enough back focus to put in an OAG so I need to use a guide scope or go unguided.

My current equipment  setup is:

CEM70EC
PlaneWave CDK 12.5 2541mm with optional 0.66 reducer
Sagitta OAG w/ASI224MC
Sony A7R4

Thanks
Kurt
