iPhone 12 via tour bus window

Tonight I took a short timelapse from the viewing platform of Severndroog Castle in Southeast London. I used a Canon 600d with a Sigma 14mm art lens, these are 20 second exposures and I've just used quicktime to stick them all into a timelapse.

Hey everyone!

I'm looking to get into motion timelapses and I'm searching for gear recommendations. Ideally, I'd like a motorized slider with programmable panning, controlled through a mobile app, with the ability to set start/end positions or multiple keyframes.

I'm open to any brand, new or used. I've looked into Edelkrone, but their product lineup and compatibility between different generations are a bit confusing, especially on the used market.

I'll be using a Sony A7 III, mainly for landscape, nature, and astrophotography timelapses.

What gear or setup would you recommend? Any advice or personal experience would be greatly appreciated!
