Re: Platesolving problem

Hello Peter, I tried to solve your image but could find a setting to do it. that the image is converted to mono is better. Downsampling of a factor 2, 3 or maybe 4 is required. Using the option CCD inspector or show button tetrahedrons you will see that maybe half of the stars are ignored. The progr...

Re: HNSKY 4.1.2 released

In the hnsky_themes version there was a problem with closing the object menu. This has been fixed in version 4.1.2a.

HNSKY 4.1.2 released

To all HNSKY users, HNSKY planetarium program version 4.1.2 has been released. The installer will install two versions of the program and creates two icons on your desktop. One version HNSKY_themes follows the Win10 themes giving it the modern Win10 look. Disadvantage is that the pull down menu text...

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.

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

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...
