Advantages of QHYCCD QHY5L-II-M
- Larger pixels — better low-light per-pixel sensitivity
- Mono sensor — ideal for narrowband and LRGB
Advantages of QHYCCD QHY183C
- Larger sensor (15.9mm vs 6mm diagonal) — wider field
- Finer sampling at 2.4µm pixels
- Higher resolution (20.4MP vs 1.23MP)
- Regulated cooling for long exposures
- One-shot color — simpler workflow
Best for — QHYCCD QHY5L-II-M
- Longer focal lengths — tighter framing on small targets
