Start of heading level 2: Messier 31: Andromeda Galaxy in Mosaic Mode End of heading.

Astrophotography from home sometimes calls for creative solutions. Although I have a garden and yard available, setting up valuable equipment outside unattended for several hours overnight always carries a risk of theft. Observing directly through a roof window is significantly safer in that regard.

Start of heading level 2: ZWO Seestar S30 Pro Review: Solar Observation & Sunspots End of heading.

In my first blog post about the Seestar S30 Pro, I documented its “first light” under a clear night sky. However, one important accessory was left untouched in the carrying case during that initial night session: the solar filter.

On the afternoon of July 14, 2026, the weather finally turned sunny, giving me the perfect opportunity to test the smart telescope during the day and catch a glimpse of our home star.

Start of heading level 2: New Addition: Ordering the ZWO Seestar S30 Pro End of heading.

On July 4, 2026, I ordered a new smart telescope: the ZWO Seestar S30 Pro via Bresser.

Start of heading level 2: How this post is written End of heading.

I am writing this post diary-style over several days and will only publish it once the telescope is delivered and I have captured the first images. This article will document the entire journey from ordering to the “first light”.

Start of heading level 2: Code Presentation at the Next Level: bat and delta in the Terminal End of heading.

Anyone who spends a lot of time in the console knows the classics: cat for quickly viewing files and git diff for checking code changes. Both have served their purpose for decades, but visually they remain stuck in the past. Yesterday, I discovered two modern CLI tools and immediately installed them on my system to replace these classics: bat and delta.

Both tools are written in Rust, extremely performant, and elevate the rendering of code to a whole new level. Here is my tool presentation and how I have seamlessly integrated them into my Zsh and Git configurations.

Start of heading level 2: Punctuality in Conference Calls: A Plea for Mutual Respect End of heading.

To be honest, it’s just getting on my nerves: it has become an absolute matter of course that at the beginning of every conference call, there’s a five-minute wait to see if any more people deign to dial in.

I couldn’t help but think of a quote by Horst Lichter (from the German talk show Riverboat) that hits the nail on the head:

“You have irretrievably stolen 20 minutes from my finite life that I could not spend in a self-determined way. That really stuck with me for the rest of my life, so that no matter when, no matter where, I’m always early, because I can determine my own time, but I don’t want to steal other people’s.”
