  1. I will have a look to Astrotortilla . Here I normally use CCDCiel for the pointing and aquisition. I also did some more testing trying to get ANSVR running . ANSVR is used by SGP users to access Astrometry.net running under the Cygwin via TCP/IP. For the Win10 Linux subsystem you have to copy the ANSVR files to the WIN10 Linux sub-system environment but solving is stopped due to errors. I contacted the ANSVR programmer Andy and he maybe will release an update of the Cygwin Astrometry.net compiled version, now at 2010 v0.38.
  2. Sorry or the late response. I missed you reply. 1) I added three cleanup lines. I don't know why the strings are in but these three lines should remove them: {clean up for some users} command1:=StringReplace(command1,'\','',[rfReplaceAll]); command1:=StringReplace(command1,'`','',[rfReplaceAll]); command1:=StringReplace(command1,'cygpath -a','',[rfReplaceAll]); {end of clean up for some users} 2) The log file is now written in the execution directory. Can you try the new version? Han win10_bash_interface.zip
  3. HNSKY + Gaia star database

    I will add the online PPMXL this afternoon. Like NOMAD it is an overkill of stars but you could compare visually the catalogs. For myself I typically use the U16 and online DSS2 images as background. My interest is deep sky fuzzies but others are interested in minor planets. If you find any (minor) problem with HNSKY please report to the HNSKY forum or send me an email so I can correct it in the final 4.0.0 version. Clear skies, Han
  4. HNSKY + Gaia star database

    Hello Carl, See screenshots below. You have to select and activate the secondary database. It will kick in if you zoom in. Every time you move around it will download and store the stars in the cache. Note that the Gaia DR1 is incomplete so many stars about 10-20% are missing. For astrometric purposes fine but less for star maps. You could also try the online Nomad or the URAT for northern hemisphere only. They go up to magnitude 20 or more. The best star database is the local U16 database with is a hybrid of Tycho and UCAC4 up to magnitude 16. Only 413 mbytes download so very compact. Gaia DR2 wil come at 25 th April but is still not complete at the bright side: https://www.cosmos.esa.int/web/gaia/dr2 I will make a hybrid again with some bright stars from Tycho2 Note that HNSKY is at version 4.0.0 RC2. Final version is imminent. Han
  5. Platesolve2 command line

    Platesolve2 version 2.2.8 never failed me except you have to write the floats with a decimal point. Also the file name should not contain a comma. I think I also trim the vales from any leading space if I remember well. Can you give a example of a command line your adding to the PlateSolve2 execution command? p.s one weird thing is the reporting. If in Windows the decimal seperator is defined as a comma, the APM file reporting uses the komma seperator. Very difficult to decode since the values are also seperated by a comma. My stacking program ASTAP is free available to test my PlateSolve2 implementation including Pascal source. Han
  6. As a test I have an old RaspberryPI operating system (2012) running under QEMU. Lazarus (0.9x) and FPC (2.6) are installed. While the compiler is too old, compiling HNSKY gives too many error messages to solve. With a new Ubuntu image I have other installation problems under QEMU. If somebody can build for me a running QEMU image of Ubuntu of Debian ARM version including the installation of FPC & Lazarus, I could retry it. HNSKY 4.0.0 is in the beta stage and almost finished.
  7. I made a little interface program bash.exe. It will accept a command line from any program executing the Cygwin bash.exe and execute the c:\windows\system32\bash.exe with the converted command line. Simplest solution is to replace the existing Cygwin bash.exe (keep a copy of the old bash.exe). Alternatively you could install it in an other directory if your are capable of setting the path to the Cygwin Bash.exe . If you place it in \astrometry\bin, you most likely have to enter \astrometry in your program. It will write a log file bash_replacement_log.txt with the command input and output for debugging at the place of execution. So the Win10 Linux subsystem installed solver can work as a replacement for the Cygwin solver. I have tested it with CCDciel only. This will not work for ANSVR & SGP Use it at your own risk. It contains a compiled executable and FPC source. Han Download: win10_bash_interface.zip webpage
  8. SGP calls the server of ANSVR and ANSVR is executing the Cygwin Bash. Since the Win10 Bash requires a slighly different command it will not work. The file name starts with /mnt/c The others execute the Cygwin Bash directly with an command-line. Same problem, a slighly different command. The Astrometry.net version running under Cygwin is what I understand a special compiled version for Cygwin, while the in Win10 installed is an Ubuntu compiled version. You post gave me an new idea. I tiny program simulating the Cygwin Bash program could work as an interface and make it work. I wil try that....
  9. Note that is not yet supported by almost all Software packages since the command line required is a little different. A program designed for the Cygwin version can't use it until it is updated. You could only use it with the command line. Han
  10. That is what I think a typical setup and confirms my impression. Planetarium programs are mainly run on an AMD or Intel processor system. When I look to the download numbers of the ARM version of CCDciel they are very low. For the next months I will work on version 4 of HNSKY. Han
  11. The new Creators edition of Win10 has a Linux sub system where you can run Linux command line programs. I have tried and can confirm that it is possible to run the Astronomy.net plate-solve package in this Linux subsystem. Below a guideline. The advantage is the pretty new Astrometry.net version v0.67. Programs as Astrotortilla and ANSVR install an old v0.38 version of 2010 compiled for Cygwin. Disadvantage is that the interface is not yet supported by several software packages. So you can only access it with the Windows command-line or my viewer/stack program ASTAP. Furthermore the Win10 Creators edition has problems with AMD graphic cards. I had trouble in getting my old working driver back. So be warned.

  12. Before I put effort in this a possible small adventure, I have to know if a ARM version is usefull for some users and secondly if I can simulate the RaspPi environment. EWHB, what is the "full software mode"? An other solution is to just buy a Raspberry PI to play with. support seems good: http://wiki.freepascal.org/Lazarus_on_Raspberry_Pi#Raspberry_Pi_3 Han
  13. The Linux Mint will be no problem. The processor in the Raspberry is ARM. Since I don't have a Raspberry, I need a ARM environment to run it in. There is an emulator QEMU. I will have a look if I can get that running. Lazarus/FPC can compile to ARM, but i have no idea what compiling problems I will face. This is what they call unexplored territory. No promises. For my information and understanding, how is the Raspberry used in your setup? Han
  14. The first Linux version of ASTAP is ready. If something is not working as expected, please inform me. Some installation instructions are provide at the web page. You have to install a local version of Astrometry.net (preferred) or use Wine & PlateSolve2 for the solving. In principle you could also use the online version of Astrometry.net manually to get the solution in a .wcs file or as a new file with an updated header but that is very cumbersome. The solution in the FITS file provided by the acquisition program is in almost all cases the target value and not accurate and should be overruled in the program. The MS-Windows version is also updated and both versions are now at version ß0.4.0 Han
  15. I work now exclusively with the freeware CCDciel. Han (ASI600MM-Cool)
