Advantages of QHYCCD QHY5L-II-M
- Finer sampling at 3.75µm pixels
- Mono sensor — ideal for narrowband and LRGB
Advantages of QHYCCD QHY10
- Larger sensor (28.1mm vs 6mm diagonal) — wider field
- Larger pixels — better low-light per-pixel sensitivity
- Higher resolution (10.2MP 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
- Well-sampled deep-sky at medium focal lengths
- Narrowband and LRGB workflows
Best for — QHYCCD QHY10
- Balanced field for most refractors
- Fast, low-noise deep-sky at short focal lengths
- Long-exposure deep-sky under any sky
- One-shot color — quick results, less processing
