Plate Solver fails to solve

SUCCESS!!! :cheer: :cheer: :cheer: I managed to make the offline plate solver to work. The problem is that when i disconnect the devices and stop INDI some of the settings are reset and need to be re-entered again. More specifically at the telescope simulator (and possibly when there is a real mount connected) at the option tab the scope properties are reset, this does not always happen. Also at the CCD Simulator (and possibly at a real camera) at the simulator config tab the CCD Y Pixel size always resets to 5.2. When i noticed this at both the simulator profiles and corrected it, the offline plate solver works flawlessly. For the atik 383l+/RC8 simulation profile the plate solve finishes in 24 secs for bin 1x1.

On another note i don't have a Raspberry Pi2 but a 3 model B yay :lol:

Congratulations! 24s is pretty fast solving for the Pi3. Maybe I can improve my own settings to make it faster.
As for saving the parameters, there is an option to load/save the parameters under the telescope and CCD tabs. There should be no need to reenter them again every time. They autopopulate correctly for me every time I connect to Indi. But you may have to go to Option>Save.

Great! And yes, make sure to save the options as El Corazon suggests.

i return to this topic in need of help since i spent a lot of time in the cold trying to figure this out and i am very frustrated and sorry if am rambling. the plate solver does not work, out of the blue, even the online simulator does not work, the solver keeps failling and i have no idea why.

What i have noticed are the following
1) I have the astrometry files installed at a usb flash drive but at the alignment configuration screen the index files are not checked even though they exist at my usb drive, i tried at all of the pi's usb ports but i have the same result. one thing i noticed is that when i open the usb drive from the file exploree i have a KIngston, Kingston1 and Kingston 2 drives is that normal?

2)when i polar align i get the message that the index files 4201 to 4207 are missing but i have the path to my usb unchanged

3) i tried logging the whole process but i am not sure if i did it correct so i include a log file, by looking at the log file i came upon this entry

CCD Simulator : "Error: Invalid range for Width (WIDTH). Valid range is from 1 to 1280. Requested value is 3362 "

the atik 38l+ has an image size of 3362x2504 is there something wrong?

Shouldn't the astrometry files be checked?

Re 1) no this isn’t normal. It happens when Linux “thinks” there was already a file system called Kingston and then the USB stick is inserted. It will then mount the USB as Kingston1. Apparently this has happend at least another time since now also Kingston2 was mounted.

When you boot your RPi3 WITHOUT THE USB STICK ATTACHED what do you see when you type

mount

? Also, does the file manager show a device or file system called Kingston? If yes, then this may indicate a system misconfiguration.

Take two. I installed ubuntu and kstars/indi/ekos and did a simulation test without any equipment and only with the online solver and the result is the same, the solver fails to solve the image. As for the usb stick issue since i installed ubuntu again i haven't seen this again.

i include screenshots of my simulation setup and todays log files. I use Kstars

Can you post screen shots of the alignment tab of Ekos and the three option tabs when clicking Options in the lower right of the alignment tab please?

here you go, note that i have not installed the index files yet as i am testing the online solver first

From the telescope coordinates: are you trying to solve around the north celestial pole? That is notoriously difficult and I’d advise you to “slew” to a different part of the sky.

EDIT Also, do you need the fits2fits option? This ONLY is needed if astrometry.net is version lower than 0.67 and should NOT be enabled for 0.67. If this doesn’t help try downsampling to 4 or 8 times and see if that helps.

EDIT 2: I see that the image already is binned 4x4 so downsampling probanly will not make a difference.

i have the default settings at the alignment tab and at the astrometry tab of the driver. I tried at a different portion of the sky, i also did that yesterday at the field with my camera, but the solver still fails. I had no issue plate solving near the pole at the field and at the simulation

Then untick the fits2fits option and try again.
