Re: Astrometry: Looking for Pascal/Delphi functions

The precession model was converted by Patrick Patrick Chevalley. The precession unit is 95 % copy of his unit. I did a few spot checks and the value matched with the old routine, so I assumed it worked correctly. Ideally you could compare the Fortran output with Pascal version. The altitude is for t...

Re: Astrometry: Looking for Pascal/Delphi functions

My program reports an altitude of 5.0. I do not include observatory height nor the pear shape of the Earth. The altitude measurements are for me of less interest.

Best regard, Han

Re: Missing INI and WCS files

Good news.

Note that the command line is described here:
http://www.hnsky.org/astap.htm#astap_command_line

And for your information, ASTAP has also photometry capabilities.

Regards, Han

Re: Astrometry: Looking for Pascal/Delphi functions

Okay I can understand sidereal time is the only way in 1867.

Tomorrow I will have a look to this last observation. Time to shutdown the computer.

Re: Astrometry: Looking for Pascal/Delphi functions

With 21:44:52.1 I get 8.4 degrees altitude. I'm not aware of anybody is using sidereal time. Maybe in 1867. Now it is UTC or Julian Day.

Re: Astrometry: Looking for Pascal/Delphi functions

And this is TheSkyX reporting: Object Name: Arcturus Name 2: HIP 69673 Object Type: Star RA (Topocentric): 14h 09m 26.2801s Dec (Topocentric): +19° 48' 17.062" RA (2000.0): 14h 15m 49.3220s Dec (2000.0): +19° 15' 21.354" Azimuth: 290° 22' 16" Altitude: +11° 08' 08" Proper Motion RA: -1,093.45 Proper...

Re: Astrometry: Looking for Pascal/Delphi functions

You make me a little worried, so I entered the data again in HNSKY and get the same result an altitude of 11.1. Delta_T on/off is only 3 seconds and did not make a difference. The UCAC4 doesn't include Arcturus, so I can't calculate the position in 1867 using proper motion. As a test , I also entere...

Re: ASTAP general use

No this splitting in R, G,G, B is a special function only to be used if you image with a colour camera and using a H-alpha filter. Then you can throw away the green and blue channel and keep the red channel only. You stack then only the red channel files. For colour stacking, you just stack the raw ...

Re: Missing INI and WCS files

The .ini is always produced. The .wcs is only produced if a solution is found. You have to specify at least the -f parameter otherwise the program behaves like a viewer: To solve: c:\PROGRA~1\astap\astap.exe -f c:\temp\m13.fits As a viewer: c:\PROGRA~1\astap\astap.exe c:\temp\m13.fits Ask me again i...

Re: Missing INI and WCS files

Hello Charlie, That is strange. The .exe file and G17 files should be in one directory. The image file could be anywhere. The .ini and .wcs should be created at the same location as the image. I tested it again as follows: c:\PROGRA~1\astap\astap.exe -f c:\temp\m13.fits This results in a m13.ini fil...
