\nThis is Saturn from Monday morning.. early Monday morning. The point of this post was to show the results of some troubleshooting with file and image management.
\nOver the last few years I have used Linux Fedora server and the ImageMagick package to manipulate and annotate astro images. To date I place the Northisup icon, a small image of the telescope and the Observatory. 10 years later this really helps!!
\nI started also annotating the filename, which contains the date and UT time, along with other info like exposure. This was provided by Firecapture. It did not however store other important information, like number of frames taken. Firecapture creates another file with all of that info.. along with a lot of other useful tidbits, like: magnitude, altitude, airmass, CMI longitude, and number of frames.
\nOver the years, files get misplaced. I doubt if I have any of the original firecapture .txt files from 10 years ago. So.. what if *all* of the text information was annotated to the astro image? Let’s make two versions, one with the minimal information package and another with it all!
\nThe above image is the original minimal.
\nThe image below is the same but with extra info added to the bottom.
\nNone of this overwrites any of the image content itself… very important!\"\"<\/a><\/p>\n

Next up is to center the icons at the top.

\nThe bash code looks like this:

\necho removing spaces in filenames
\nfor f in *\\ *; do mv “$f” “${f\/\/ \/_}”; done

\nfor i in 2022*.png
