Advantages of QHYCCD QHY163M
- Larger sensor (22.2mm vs 12.85mm diagonal) — wider field
- Larger pixels — better low-light per-pixel sensitivity
- Higher resolution (16.4MP vs 8.3MP)
- Mono sensor — ideal for narrowband and LRGB
Advantages of ZWO ASI585MC Pro
- Finer sampling at 2.9µm pixels
- One-shot color — simpler workflow
Best for — QHYCCD QHY163M
- Balanced field for most refractors
- Well-sampled deep-sky at medium focal lengths
- Long-exposure deep-sky under any sky
- Narrowband and LRGB workflows
Best for — ZWO ASI585MC Pro
- Longer focal lengths — tighter framing on small targets
- Well-sampled deep-sky at medium focal lengths
- Long-exposure deep-sky under any sky
- One-shot color — quick results, less processing
