Tried stacking with and without a light pollution filter from my backyard in Phoenix

Last week I shot the Orion Nebula with my 8-inch scope. I took 30 lights without a filter, then another 30 with a cheap CLS clip-in filter. The unfiltered stack was a washed-out orange mess. The filtered one actually showed some dark dust lanes and the core color. The difference was night and day, literally. Anyone have a favorite filter for heavy city glow?

Remember when you had to hand label a thousand images for a simple model?

Back in 2018, I spent a whole week labeling street sign photos for a college project. Did about 50 an hour, my eyes were crossing. Then last month, I used an auto-labeling tool on a similar dataset. Finished the same work in under two hours. The accuracy was maybe 95% right out of the gate. It's wild how that grind just vanished. Anyone else have a 'before and after' moment with a specific AI tool?

Question about a student who thought a strong password was enough

A kid in my 8th grade class in Denver last month argued that his 12-character password with symbols made him 'unhackable,' so I had to explain why he still needed two-factor authentication on his gaming account.

My old star charts from the 90s are falling apart, but I still use them more than any app on my phone.
