SVBONY SV226 M54 Telescope Filter Drawer - Fast Dual-Filter Swap

In this review the SVBONY SV226 M54 Filter Drawer shows itself as a practical accessory for deep sky imagers who need fast, reliable filter changes without vignetting. Built around a dual magnet design and a 20mm-thick, CNC-crafted body, this filter drawer is aimed at astrophotographers using full-frame setups who want secure, repeatable filter holds and quick swaps during a session. The bottom line: it delivers sturdy construction and efficient workflow improvements for anyone shooting multi-filter sequences on a telescope.

Key Features

• Dual magnet stability: Two magnets hold each 2in filter firmly in place so filters do not shift or fall during handling or imaging.
• Full-frame compatibility: The M54 mounting and included M54-M48 adapter ensure a wide, vignetting-free field of view for full-frame cameras.
• Two filter holders: Dual drawers let you swap filters quickly without disassembling the imaging train, saving time during critical capture windows.
• Locking mechanism: A locking screw prevents gaps that could cause light leaks during long exposures, keeping frames clean.
• CNC one-piece construction: The machined body gives the drawer strength and durability for regular field use and repeatable fits.
• Compact storage box: A plastic storage case keeps the unit and components organized and protected when not in use.

Who It's For

The SV226 is best suited to amateur and hobbyist astrophotographers who use 2in filters and want to run multi-filter imaging sessions on a full-frame or large-sensor camera without worrying about vignetting or slow manual swaps. Its secure magnet holders and locking screw make it practical for long exposure deep sky work.

Those who should look elsewhere include imagers who require motorized filter wheels or who do not use 2in filters at all; if you need automated sequencing controlled from a computer, this manual drawer will not replace a motorized wheel.

Pros & Cons

Pros

• Well-built CNC body and secure dual magnets provide reliable filter retention and durability.
• Designed for full-frame use with an M54-M48 adapter to reduce vignetting for wide-field imaging.
• Two quick-swap filter holders speed workflow and reduce downtime between filter changes.
• Locking screw and tight tolerances prevent light leaks during long exposures.

Cons

• Manual drawer mechanism is not motorized, so it is not ideal for fully automated filter sequencing.
• Limited to 2in filter holders, so other filter sizes require separate adapters.
