Using guide data - mount analysis/polar alignment

I have been using the plot in the guiding interface for analysis of my mount (HEQ5) and for polar alignment in a similar way as you can do with PHD Guiding.
I wonder if there are log-data for the guiding proces somewhere on the system that I could use instead of the plot?

Has anyone tried something similar?

Nothing is stored, but what kind of data is required? Besides timestamp, ra and dec deflections?

The data I use in PHD Guiding is:

Frame = image number
Time = Seconds since guiding began
Milliseconds the RA motor was turned during this frame
Amount of error (deflections) in RA (in pixels or ") from beginding of guiding
Milliseconds the DEC motor was turned on during this frame
Amount of error (deflections) in DEC (in pixels or ") from beginding of guiding

Very nice, if this could be in a CSV-format.

Maybe also some "header"-data coresponding to this guiding session:

Calibration Start 2015-01-04 01:22:26
Exposuretime = 1000 ms
Pixel scale = 4.88 arc-sec/px, Focal length = 220 mm
Calibration Step = 1000 ms
Star position = 556.183, 629.851 in pixels
RA angle = 23.345 degrees from vertical top clock-wise

Could this make sense to put in a log file somewhere?

I added guide_log.txt under where ever your local kstars files are installed. For me it's ~/.local/share/kstars

It contains only a subset of the data above.

Thank you - I'm looking forward to testing this next time the night sky is clear here in Denmark :-)

Hi!

I'm very interested in doing precisely the same - use guide data to analyse my mount and polar alignment. I cannot find any guide_log.txt anywhere - my files are in ~/.kde/share/apps/kstars, but no guide log there. Running ubunti 15.04. Where can I find this? And what are your experiences of it so far?

Hi!

magnus@herbert:~$ cd ~/.local/share/kstars
bash: cd: /home/magnus/.local/share/kstars: Filen eller katalogen finns inte (english: no such file or folder)

I'm using ubuntu 15.04, have installed kstars and indi with apt-get, no manual settings or other stuff. Are you referring to another system, or is something missing in mine?

I have ~/.kde/share/apps/kstars:

magnus@herbert:~/.kde/share/apps/kstars$ ls -l
totalt 75508
-rw-rw-r-- 1 magnus magnus 77198522 okt 18 20:39 deepstars.dat

-rw-rw-r-- 1 magnus magnus 78 okt 26 16:38 wishlist.obslist

But no guide_log there.

Did you install kstars-bleeding from my PPA or KStars that comes with Ubuntu 15.05?

Hi!

This is odd. I have the kstars package:
magnus@herbert:~/astro$ dpkg -l | grep kstars
ii kstars 4:4.13.3-0ubuntu0.1 amd64 desktop planetarium for KDE
ii kstars-data 4:4.13.3-0ubuntu0.1 all data files for KStars desktop planetarium

I did add the ppa, according to the instructions on the download page:

magnus@herbert:~/astro$ sudo apt-add-repository ppa:mutlaqja/ppa
Latest INDI Library and drivers!
Mer info: launchpad.net/~mutlaqja/+archive/ubuntu/ppa
Tryck [RETUR] för att fortsätta eller ctrl-c för att avbryta

gpg: /tmp/tmpov3kjr2x/secring.gpg: nyckelring skapad
gpg: /tmp/tmpov3kjr2x/pubring.gpg: nyckelring skapad
gpg: begär nyckeln 3F33A288 från hkp-servern keyserver.ubuntu.com
gpg: /tmp/tmpov3kjr2x/trustdb.gpg: tillitsdatabas skapad
gpg: nyckel 3F33A288: publika nyckeln "Launchpad INDI" importerades
gpg: Totalt antal behandlade enheter: 1
gpg: importerade: 1 (RSA: 1)
OK

Then apt-get update. But there is no kstars-bleeding:

magnus@herbert:~/astro$ sudo apt-cache search kstars
kstars - desktop planetarium for KDE
kstars-data - data files for KStars desktop planetarium
indi-sbig - INDI SBIG Santa Barbra Instrument Group CCD Driver
kstars-data-extra-tycho2 - Tycho-2 star catalog for KStars
libapogee-dev - Alta camera control library (development files)
(the rest of the output was indi-related)

And when I try to add the astrometry.net-ppa I get an error:

magnus@herbert:~/astro$ sudo apt-add-repository ppa:mutlaqja/astrometry.net
Cannot add PPA: 'ppa:mutlaqja/astrometry.net'.
Please check that the PPA name or format is correct.

What's wrong here?

What do you get when you run:
apt-cache policy kstars-bleeding

Also, the astrometry PPA was deleted, I added a topic on that on the main forum page.

N: Kunde inte hitta paketet kstars-bleeding
