Advantages of QHYCCD QHY5III200M
- Larger pixels — better low-light per-pixel sensitivity
- Mono sensor — ideal for narrowband and LRGB
Advantages of Atik Horizon II
- Larger sensor (22.2mm vs 17.6mm diagonal) — wider field
- Finer sampling at 3.8µm pixels
- Higher resolution (16.3MP vs 1.78MP)
- Regulated cooling for long exposures
- One-shot color — simpler workflow
Best for — QHYCCD QHY5III200M
- Longer focal lengths — tighter framing on small targets
- Fast, low-noise deep-sky at short focal lengths
- Narrowband and LRGB workflows
Best for — Atik Horizon II
- Balanced field for most refractors
- Well-sampled deep-sky at medium focal lengths
- Long-exposure deep-sky under any sky
- One-shot color — quick results, less processing
