TOPIC: ISO in file names

ISO in file names 2 months 2 weeks ago #24983

Hi!

Just recently I've had my first night session running KStars/EKOS and one thing I am missing is an option to append the ISO to the prefix (just like time stamp and duration). Since taking notes during a session is one of my weak points this would really come handy.

I'd like to change this to be token based instead of check boxes, it would be a lot more flexible this way.

I usually just add this info to the file name under which I am saving the images. If all else fails, the info will also be accessible later in the FITS header/EXIF.

Which Linux tools read FITS headers anyway? Also, I haven't found any picture viewer that would display FITS files correctly, other than RawStudio which I found to be clumsy.

El Corazon, that would be a perfect solution if only I wouldn't forget to change the object name as much as I forget to take notes what ISOs were used. I'm afraid it's something that has to be done automatically otherwise it won't be fool (that's me) proof.

You can actually view FITS files just like any other image file now in KDE in Dolphin and Gwenview. You probably need a recent KDE though like KDE Neon or Kubuntu 18.04

Ah, that's it. Gwenview is my default viewer but it can't handle FITS files as of yet neither in Suse Leap 42.3 nor Kubuntu 17.10. So I will upgrade to "Bionic Beaver" once it has been released. Thanks for the hint!

Just double click the fits file in Linux and KStars will open. Then go to File>FITS Header to see all relevant information.
Other options for Linux are ImageJ, which also allows you lots of other manipulation of your file including separating the channels, or fv FITS Editor.

The standard graphical tools to work with fits file are ds9 and fv.
But in your case a command line solution is probably better because this allow to write bash script to automatically move or rename your files based on some fits keyword.
You can use fitsverify, packaged in Debian/ubuntu, for that.
For example to extract the exposure time:
fitsverify -l IMAGE_001.fits | grep EXPTIME | awk '{print $5}'

If you just want to look at the header, the easiest is fv FITS Editor, since when that opens it brings up a button labeled Header. You just click that and you get a neat summary of your entire file.
Actually, thanks to Herrhausen for starting this topic. Had I not responded and opened one of my own files from the prior night with fv I would not have found out that I had switched off the cooler on my ASI1600. I had been blaming the large background noise on light pollution and poor seeing. The FITS files showed me the actually temperature when I took the picture and that was decidedly a lot warmer than I had intended it to be.
So, looking at these FITS headers in a convenient manner can be quite useful once in a while.

pch and El Corazon, thank you so much! That really solves my FITS problems. These are exactly the right tools for the job! Never heard about it before...
