Warning: stacked astrophotos from suburban skies are overrated

Last month I drove 3 hours out to a dark site in West Texas to shoot the Orion Nebula. Everyone on here says stacking dozens of exposures from your backyard gets you 90% of the way there. I tried that for 2 years from my driveway in Austin with a modded DSLR and an old tracker. The suburban light pollution never really goes away no matter how many frames you stack. At the dark site I got one single 3 minute exposure that looked better than my 4 hour stack from home. The background was actually black and the dust lanes popped without me having to fight gradients. Does anyone else think we push the "shoot from home" advice too hard when clear dark skies are only a tank of gas away?

Well I guess my light polluted driveway is just out here collecting social security then.

And honestly, Max, I've been there - tried lugging my telescope out to some dark spot only to realize I forgot a critical part. What finally helped me was just getting a simple light pollution filter for my driveway setup, made a world of difference. Sure beats fighting for parking at the local park.

Oh man, I gotta jump in here real quick. Light pollution filters are great for certain things like looking at the moon or bright planets, but they don't actually fix light pollution for deep sky stuff like galaxies and nebulas. They're really just blocking out certain wavelengths from streetlights, not the overall sky glow that washes everything out. I learned that the hard way after buying a cheap one thinking it would let me see the Andromeda Galaxy from my backyard. So yeah, they help with planetary viewing for sure, but don't expect miracles if you're trying to spot dim fuzzy objects through that orange haze.
