Drizzle ➝ BlurX ➝ Downsample: The PixInsight Trick That Fixed Artifacts I Didn’t Know I Had

Welcome back to Hidden Light Photography! Have you ever wondered if working with 2x drizzle all the way through PixInsight is actually "hurting" your final result? I got a viewer question about down-sampling mid-process — and to be honest, I’d never heard of that before. But when I tested it... something clicked. This video breaks down a theory you might not have seen discussed much — the idea that drizzling helps early processing (like BlurXTerminator), but starts amplifying artifacts if you leave it full-res the entire time. So what happens if you down-sample after BlurX, but before star removal and stretching? 💥 In this video, you’ll see: • What 2x drizzle does for your data • How BlurX reacts to high-res inputs • Why down-sampling before StarX can actually CLEAN UP your removal • Real-world before/after comparisons • Artifacts that "vanish" in the down-sampled version • How this trick improved luminance star removal Whether you're chasing perfection in your stars or just looking to squeeze more signal out of your data, this simple change might be a game-changer. 🧭 Search my entire video library by keyword (like “PixInsight”, “filters”, or “guiding”): 👉 https://hiddenlight-photography.com 🛒 Want to upgrade your rig or support the channel? 👉 https://www.highpointscientific.com/?... 🔧 My 2025 Recommended Equipment List: 👉 https://hiddenlight-photography.com/b... 💬 Have YOU ever tried down-sampling mid-flow?
