- Automated LRGB and narrowband filter changes for mono imaging
Astrophotography Fit
Best for mono rigs that need repeatable LRGB and narrowband filter sequencing.
QHY CFW3M-US Filter Wheel turns a monochrome camera into a practical imaging system by automating filter changes. The right wheel depends on sensor size, filter size, back-focus budget, and how many channels you want loaded at once.
Choose filter diameter conservatively. Undersized filters vignette; oversized filters cost more but protect future camera upgrades.
Best paired with
- Monochrome cooled cameras and matched LRGB/narrowband filter sets
- Autofocus routines with filter offsets
- Rigid threaded imaging trains with known back focus
Not recommended for
- One-shot color-only workflows
- Camera sensors larger than the filter size can illuminate cleanly
- Ultra-minimal travel rigs where weight and back focus are tight
