Alignment/Plate solve problems

Getting closer to a running system and the last thing in the basic setup is getting the solver to do its thing, but for some reason it's not even trying.

I'm trying the alignment procedure with telescope simulator and CCD simulator.

I keep getting this in the dialog when trying to solve:
2015-03-11T19:17:37 Solver failed. Try again.
2015-03-11T19:17:37 Reading input file 1 of 3: ""...

2015-03-11T19:17:35 Solving first frame near the meridian.
2015-03-11T19:15:26 Idle.

So immediately after the solve should start the solve-field decides that it can't do it.
I did a couple of runs with actual images in the console and they worked fine (apart from taking a long time, but that can be tweaked).

What could be the problem?

If you're using the CCD simulator, do you have GSC installed? Also, are you trying to check for polar alignment errors above? You must select "GOTO" for regular solving.

Over the last days solving is not working at me either. I get this output from aligment module:

I have tried both online and offline solver and get the same "Solver failed" Tried with both canon and lodestar.

Jasem, yes GSC is installed and the images show up ok. It "captures" the image and when solve should start, it doesn't start looking at the index files, just says that "solver failed" basically immediately after reading the image file. It doesn't even try to extract sources from the image.

And, yes I'm trying to familiarize myself with the polar align routine before going out in the cold :)

Not sure what's going on, I just installed the latest astrometry.net it solves just fine. Try it on sample images with different parameters

It was my fault - my update of astromtry.net was missed during the last week - everything is ok now :-)

Running kstars in debug revealed a QT issue with FITSviewer. Didn't have time to pursue it further, but it seems that it either does not create the temporary file or pass over the file name or some such thing since the source extractor does not have a file to work with.

As compared to Jensen's
2015-03-11T20:11:01 Reading input file 1 of 1: "/tmp/fitsfG3621"...

The number of input files (1 of 3) in the message I assume is due to the polar alignment routine.

I'm running kstars/indi/ekos under ubuntu 15.04, no Kubuntu desktop so some libraries might be missing. Going to try after installing Kubuntu desktop and see what happens.

I don't think it is a problem with astrometry.net installation since solve-field works fine from the command prompt with actual images. Using the same images that solve from the command prompt as GOTO reference images in ekos gives the same message as in the original post.

Quick update.
Seems that even installing kubuntu desktop on ubuntu 15.04 did not help. Installed kubuntu 15.04 from daily image and it works fine there.

I think there is still som problems with the alignment module. I have tried on Ekos VM and my usual setup on xubuntu 14.10 with the daily updates.

Versions are:

astrometry.net 0.52+r3778.2 amd64 Astrometry plate solver
kstars-bleedin 5:15.04+r516 amd64 desktop planetarium for KDE
indi-full 1.0+r1.207~u amd64 Instrument-Neutral Device Interfa

I can't get my real cameras to solve, but the simulator can. I'm using gphoto (canon 1100D) and sx lodestar. Whenever I try it just seems to get no solutions on real cameras.

What can I do to investigate further. Approx. to weeks ago everything was working...

Please check the FOV, is it calculated correctly? Has it changed from before?

I think the FOV is the same as before. I have a Canon 1100D (4290x2856 pix size 5.18) and 1000mm focal length.

The FOV is calulated to 76.4' x 50.9'

Here is the result of starting the solver:

The solver's RA is set 17h 37m 27.11s, and DEC is set to 90 degrees, is your object within 30 degrees from these coords?
