Modeling indicates arrays of small seeing-limited telescopes are more cost-effective than single large seeing-limited ones for single-object observations, with single diffraction-limited telescopes preferred only below 20-28 magnitudes depending on architecture.
A two-stage deep learning pipeline (HT-LCNN detector + VGG6 classifier) trained on augmented real and simulated data detects streaks in OmegaCAM frames with F1 > 0.95 on test sets and 0.99 precision on real 2023 data, uncovering 25,335 streaks including >20% uncatalogued objects across 1.2 million f
