    New plate solver program

    FYI, Latest ASTAP version can add deep sky annotations to the solved image: Han
  2. FYI, for the HNSKY planetarium program new star databases are released based on the Gaia DR2 release of the ESA. G16: Native HNSKY database up to Johnson V magnitude 16 containing 60 million stars. Magnitude is the calculated Johnson-V magnitude. This V magnitude is close to the visual magnitude but not the same. 455 bright Tycho2 stars are added for completeness. Unpack in the program directory, typically c:\program files\hnsky or for Linux /opt/hnsky. Recommended for visual observers. G17: Native HNSKY database up to photographic magnitude 17 containing 105 million stars. Magnitude is the unmodified Gaia BP. 455 bright Tycho2 stars are added for completeness. Unpack in the program directory, typically c:\program files\hnsky or for Linux /opt/hnsky. Recommended for astrophotographers. G18 Native HNSKY database up to photographic magnitude 18 containing 208 million stars. Magnitude is the unmodified Gaia BP. 455 bright Tycho2 stars are added for completeness. Unpack in the program directory, typically c:\program files\hnsky or for Linux /opt/hnsky. Recommended for astrophotographers. Download HNSKY 4.0.0g to see the faint stars of this database.

    New plate solver program

    Hello Russell, The database is equinox 2000, epoch 2016 or 2017, so the result is equinox 2000. With the following command it works with your FITS file: astap.exe 0.235,0.8236,0.0174,0.0174,999,C:\temp\s1.fit The image size is not recognised, so you have set it in tab alignment at around 1 degrees. start magnitude 8 and limiting at 12 or higher. The get the image size recognition implemented, i have to read binning, telescope focal length and chip size. I will do that in next version. The platesolve2 command will override it anyhow. So your FITS is a good test case. I changed the parameter handling back to original setup in version 0.9.46. The version 0.9.45 doesn't accept filenames as first parameter. So you can't use ASTAP as viewer anymore. Han

    New plate solver program

    Russel, The Astap PlateSolve2 command line had a bug with the regions. The program internally doesn't use regions anymore but a radius in degrees. I forgot to convert it correctly for the command line. The program accept a space in the file name. I have now improved it such that is also accept double spaces. Version 0.9.45 Note that the new commands can't be mixed with the platesolve2 command line. So either use the PlateSolve2 command line or the newer more flexible command line. If you use the PlateSolve2 command line, you have to set the magnitude range ones in the program. Widest range is start-magnitude at e.g. 8 and limiting-magnitude 16.5. A smaller range will speed up plate solving. If you leave the program FILE, EXIT these two settings are saved. PlateSolve2 style command line: PlateSolve2.exe 4.65671913109554,1.5707963267949,0.011990411961201,9.58185759344887E-03,999,C:\astap\s1.fit New style: Astap.exe -ra 266.81 -dec 90 -fov 0.687 -r 20 -f C:\astap\s1.fit or since details (ra,dec, exposure, FOV) are in the fits header: Astap.exe -r 20 -f C:\astap\s1.fit Solving an image near the celestial pole has been tested. But your declination is at the pole which could be problematic. Not tested. If you load a FITS file in Astap you can see which kewords are read and fields filled from the FITS header. It should read the telescope position (viewer) and FOV. If your FOV (field of view) is not filled this is not so important. However you could send me a FITS file to see why it is not recognised. The programs works with CCDciel and I have briefly tested it with APT and SGP. Some instructions are at the webpage. Han

    New plate solver program

    Hello Russel, The APM file should be produced at the same location as the image. Let me check again (tommorow). About the spaces, it should be possible to use them in the flename but I have added the additional new command line (for CCDciel interface) later, so possibly it is no longer working. Let me check if it stil works. So it accept two kinds om command line. The Platesolve2 style and the new one. ASTAP doesn't need an accurarate image scaling. It will look to the ratios of the pyramids sides which are independent of the image scale. However I uses the the image scale for the search window. This search window is "moved" around in the database to find a match. So it should roughly be correct. For FITS file it will look to the header keywords for the image scale. If you use the Platesolve command, you have to set only the 1) start magnitude and 2) limiting magnitude and 3) maximum search field manually in ASTAP settings With the new command line you can set them using the command.

    Non-goto plate solving

    Are you trying to indentify faint fuzzies? Then displaying the plate solved image in a planetarium program as background to a map is your best option. Second option is to setup a planetarium map next to FITS viewer and move the mouse around to find a coordinate match. The first option is the best. CDC and HNSKY can do this.
  7. For those interested or have a use for local plate solver the following: The free ASTAP stacking program has now it’s own plate solver. It can process images in FITS format but also JPG, PNG, TIF file and give the image centre position and orientation. It is command line compatible with PlateSolve2 and produces an similar APM file. It can also update the FITS headers or convert JPG,PNG, TIF to the FITS format. Other outputs options are WCS or INI files containing the solution. In addition it comes with a flexible viewer and stacking menu for FITS files. For plate solving a star database of 420mbytes needs to be downloaded and extracted to the program directory. With an good estimated position, the solution is found within seconds. With an offset of 20 degrees in minutes. Available for MS-Windows and Linux. Still in development and at version ß0.9.39 Feedback is welcome. Han Link: http://www.hnsky.org/astap.htm It has in principle only three settings, 1) start magnitude and 2) limiting magnitude and 3) number of regions to search. The limiting magnitude is a value for the faintest stars in an image of 10 seconds exposure. For FITS this value is automatic adapted to the exposure time. For other formats this has to be manually entered or specified in the command line. There is no need to define the pixel scale or the image astronomical size.
  8. The Gaia DR2 star catalogue is released today. For people who are interested, it is online accessible by the planetarium program HNSKY 4.0.0.f It could be slow the coming days since a lot of gbytes are downloaded from Vizier. Most people will see no the difference. The current catalogues are sufficient accurate. Download HNSKY: www.hnsky.org/software.htm
  9. This is an interesting development. I think in the introduction or documentation you should describe a little more about the pre-conditions and installation. As far I understand you need either: 1) A Linux system with a local astrometry.net installed. 2) Win10 64 bit Creators edition, Linux sub system installed. E.g. you could use my guideline as a start: http://www.hnsky.org/linux_subsyst.htm 3) Windows system with Cygwin version of Astrometry.net v0.38 ?? Programs should be able to execute astrometry.net locally but this will help for the programs which only have a web interface to astrometry.net. Han
  10. The latest version 0.9.23 can stack L+R+G+B or RGB+L images. Secondly you can select images from several objects in different directories and run the stacking in one run. The stack results are reported in a results tab for easy access. The program is actively in development and could be updated on daily basis. Bugs could be there. You could help with the development by trying the new version with your raw images and send reports or send your raw images for testing by me. Or you could suggest new features and possibilities which are missing. For images of the same dimensions/camera the fast internal alignment routine could be used. For different dimensions the astrometric solution could work. Han
  11. It is distributed with a GNU General Public License 3+ as published by the Free Software Foundation. It is programmed in Object Pascal (Lazarus, FPC) It is up to now a single developer project by me. At the moment I'm most interested in user testing and experience and suggestions for improvement. It works for me, but maybe not for everybody. I don't expect anybody to support the code. You can use it either as FITS viewer & editor with some tools as a basic CCD inspector and main use is now stacking of images. So it has a kind of dual personality. The initial basic viewer HNS_FV was developed about 15 years ago and only the last 5 months ago the development was restarted and took some major steps forward. Han
  12. ASTAP, the free Astrometric STAcking Program version 0.9.9 can now stack deep sky FITS images without any plate solving program. It has a new internal "star alignment" routine. It will compensate for drift in RA,DEC, rotation and flipped images. http://www.hnsky.org/astap.htm feedback is welcome. Han ------------------------------------------------------------------------------------------- Star alignment routine This option allows stacking without any external program. It is not suitable for mosaics. No settings, fully automatics alignment for shift in x, y, flipped or any rotation using the stars in the image. The program combines four close stars into a pyramid and compares the six pyramid dimensions with pyramids of the first/reference image. It selects at least the six best matches and uses the center position of the pyramids in a least square fitting routine for alignment.
  13. Hello all, Version 4.0.0 of the free "Hallo Northern Sky" or HNSKY planetarium has been released. For MS-windows and Linux. Any feedback is welcome. webpage: http://www.hnsky.com/software.htm Han The major changes: Program: - Improved swipe functionality. - New improved telescope cursor, the telescope position is now shown as a correct sized and orientated rectangle. Orientation can be set manually with mouse wheel while holding CTRL key down. - Added possibility to design mosaics. (measuring frame on, hit HOME. To remove rectangle hit CTRL+DEL) - Goto menu has "slew to" functionality if "track telescope is on". - Three-state check-mark for asteroids and comets. Grayed=all, checked=auto - Three-state check-mark for star names. Off=bright stars only, Grayed=supplement stars only. Checked=All star names. - Vizier online server for star catalogue can be set in settings. - Server link with APT en CCDCIEL. Catalogues: - Added PPMXL online star catalog. - Added Lynds (LBN) supplement containing 1125 bright nebula as supplement and brightest to the deepsky level 3 database. - Added Hickson Compact Groups of Galaxies (HCG) as separate supplement and to the deepsky level 3 database. New telescope rectangle: Mosaic design:
  14. 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.
  15. 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
