Svbony SV226 filter drawer M54-M48 for deep-sky photography 📷
Description:
This compact telescope filter drawer makes swapping 2-inch filters quick and reliable for deep sky and planetary imaging, speeding up transitions during observation sessions. The unit suits setups that need a slim, secure holder compatible with M54 to M48 threads, and it helps reduce stray light during long exposures.
Key Points
The drawer accepts two 2-inch filters, so you can keep a narrowband and a light pollution filter ready to hand. Smooth operation is one of its strengths, letting you change filters without fumbling at the eyepiece or camera port. The design concentrates on practical stability, with features that aim to hold filters firmly in place during tracking and framing.
Magnetic retention aids stability and the locking screw reduces the risk of light leak when capturing long exposures, according to the manufacturer. A hard plastic storage box is included for neat transport and organised storage of the accessory between sessions. Consider that the unit adds 20mm of thickness to the optical path, which is meant to preserve a wide field of view while fitting common imaging train setups. 🔭

Usage Recommendations
Fit the drawer into an imaging train where a slim profile is required to avoid vignetting. For deep sky long exposures, use the locking screw to ensure no gap remains between the filter and the tube, as light intrusion can affect faint detail. The dual magnet mechanism is helpful when making quick swaps during a session, however ensure threaded connections are secure before slewing the mount to avoid accidental movement. ⚙️
When using heavy filters or multiple adapters, check that your focuser or adapter chain provides sufficient support, because the additional components can alter balance and back focus. The storage box keeps the unit and spare components together for travel and reduces the chance of scratches to delicate filter surfaces. 🔧
