Advantages of QHYCCD QHY294C Pro
- Finer sampling at 4.63µm pixels
- Higher resolution (11.7MP vs 10.2MP)
Advantages of QHYCCD QHY10
- Larger sensor (28.1mm vs 23.1mm diagonal) — wider field
- Larger pixels — better low-light per-pixel sensitivity
Best for — QHYCCD QHY294C Pro
- 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
