Advantages of QHYCCD QHY163M
- Larger pixels — better low-light per-pixel sensitivity
- Regulated cooling for long exposures
- Mono sensor — ideal for narrowband and LRGB
Advantages of Canon EOS R7
- Larger sensor (26.8mm vs 22.2mm diagonal) — wider field
- Finer sampling at 3.2µm pixels
- Higher resolution (32.5MP vs 16.4MP)
- One-shot color — simpler workflow
Best for — QHYCCD QHY163M
- Balanced field for most refractors
