Advantages of ZWO ASI385MC
- Finer sampling at 3.75µm pixels
- Higher resolution (2.12MP vs 1.78MP)
- One-shot color — simpler workflow
Advantages of ZWO ASI220MM Mini
- Larger sensor (17.6mm vs 8.4mm diagonal) — wider field
- Larger pixels — better low-light per-pixel sensitivity
- Mono sensor — ideal for narrowband and LRGB
Best for — ZWO ASI385MC
- Longer focal lengths — tighter framing on small targets
- Well-sampled deep-sky at medium focal lengths
- One-shot color — quick results, less processing
Best for — ZWO ASI220MM Mini
- Longer focal lengths — tighter framing on small targets
- Fast, low-noise deep-sky at short focal lengths
- Narrowband and LRGB workflows
