Tried a star tracker for the first time and got a surprise

I snagged a used iOptron SkyGuider Pro off Craigslist last month, figured I'd finally get into deep-sky shots. First night out, I set it up in my backyard near Portland and aimed at the Orion Nebula. Instead of a crisp nebula, I got these wild star trails that looked like a kid's doodle. Turns out I had the polar alignment way off because I didn't level the tripod first. Learned that 2 minutes of setup saves 2 hours of frustration. Has anyone else messed up their first tracker try in a funny way?

Fixing that polar alignment was the game changer for me too. After wasting three nights on blurry shots, I realized leveling the tripod first was the key then using the polar scope to center Polaris. Drift alignment also helped a lot for longer exposures without a guide scope. Once I got those two things down, my 60 second subs came out nearly perfect. You'll get it sorted fast since you already know what went wrong. Just keep practicing and it'll click.

Wait, you're telling me leveling the tripod first actually matters? I spent a whole night screwing with the polar scope wondering why Polaris kept sliding off the crosshairs like a greased pig. Turns out I was just fighting a tilted tripod like an idiot. Drift alignment though, that's the real patience test. I'd rather watch paint dry than do that again, but you're right, it works.
