Allsky plate solve

I am trying out the allsky plate solver, but find its performance much slower than ANSVR, I can’t find many settings to change in order to try to get it to be as fast as ANSVR. Both have the same index files but it’s taking much longer… 16" vs 6" in ANSVR.

Anyone familiar with both and know what needs to be changed? Both use local


Which kind of solve … plate or blind. If you use like plate solve is really slow. Anyway you use just one time I don’t think 10” is a problem. Try to contact the developer .

All the best

Having lots of difficulty with All Sky plate solver, sorry.

Even hangs Voyager where the abort button does nothing. [Abort Request]

Database gets locked while in the Allsky plate solver program [FireDac][Phys][SQLite]Error: Database table is locked; SolverLog

Honeslty I’ve never heard of this AllSky Plate solver until Voyager, Everyone I know uses ANSVR :slight_smile:

I’m trying to setup a reproducible example for you but struggling with the entire process now, I’ll try again later.

Hi Martin -

I just tested All Sky Plate Solver on my local setup and it’s working fine with Voyager, so may be something in your configuration.

ASPS is just a GUI shell on top of the ANSVR engine. Since the shell does send commands to ANSVR, it can certainly give you different results in terms of speed compared to when you execute ANSVR directly.

I would focus on getting ASPS working standalone before testing it from Voyager. I know you said it was working earlier, does it still work if you execute a plate solve from the ASPS interface?

The fact that you are getting that SQLite error means ASPS is not going to work properly. I would try rebooting your PC and starting over.

Voyager is probably not hung, it is just still waiting for ASPS to return. Look under Setup, Plate Solve in Voyager. There is a maximum solve time setting - Voyager will not abort until this time out has been reached:

Also, would be interested if you have tried as your plate solver from Voyager. I realize you may not have Internet connectivity from the field, but let’s focus on getting your plate solving working with Voyager first.


I can confirm that ASPS works well on my system. I suspect you have a configuration problem.

While testing AllSkyPlate Solver I run into this error occasionally which causes the database locked. Strange. Just repeatedly trying the same file over and over again.


Definitely not a Voyager thing, but not very confident in the ASPS at moment.

Here are two log files of Ansvr and ASPS.

Strange how the ansvr pixel scale is larger, as if the file is reduced. Perhaps the other software is doing something to the .fit files.

Anyway this is probably for the AllSky Developer, but I am no longer interested in pursing this at the moment. Thanks for your time :slight_smile:

Hi Martin,

Understood, it does sound like something you would need to get help from the ASPS developer.
It’s worked quite well for me, but I understand you may not be interested in trying to figure it out.

From the error message it appears a filename being stored in the database is too long for the space in the column. That could certainly cause issues.

Another free plate solver supported by Voyager is Platesolve2, although it is not a blind solver.


Hey, so I renamed my test file to a very short “” and it seems to be working much more consistently. I haven’t looked how Voyager names files yet but I guess my old files were fairly of long for ASPA…

I think it was trying to write the file in the database for caching perhaps.

I assume when voyager is running automatically it’s a background “” file anyway during the centering routine so probably would not have had this issue anyway. I was just testing offline the solving from one of my existing captured files.

The speed thing would be my last concern if it could be on par with ansvr, I just can’t seem to find settings to adjust. Perhaps because ansvr uses pixel scale and ASPA uses focal length and camera scale… Not sure… Anyway thanks again.

Regarding the speed, make sure your binning settings match when doing your comparison. I think Voyager defaults to 1 x 1 for blind solving but I changed it to 2 x 2 and have been very happy with speed of ASPS with 2 x 2 binning. In fact, I feel like it gets the job done faster than with local ANSVR/SGP.

Kind regards,


I would just use PlateSolve2, its free and works very well with Voyager.

Pay attention to get the right size and binning for doing plate/blind solving … others software resizing crop and binning without asking … Voyager allow user to choose crop and binning … please choose the one is better for you. A 16mp is better to use bin2 and half frame. I never see ASPS lower than ansvr …
