In astrophotography, every accessory may affect the quality of the final image - and "small parts" such as filter drawers are often the key to improving the experience. The SV226 M54 filter drawer may seem simple, but it has done a lot of work in compatibility, stability, and operational feel, allowing the performance of the entire set of equipment to be released more smoothly. Next, let's take a look at its highlights.

Core Features

Dual - Magnet Lock: Rock - Solid Filter Security

The SV226 M54 uses a dual - magnet design to keep filters firmly in place. Unlike flimsy holders that risk filter slips during long exposures, these magnets create a “grip” that resists movement. No more worrying about accidental drops or misalignments that ruin hours of setup!

CNC - Machined Durability

Crafted via CNC one - piece molding, this filter drawer is built to last. The high - grade aluminum alloy balances strength and lightness. It also shields filters from dust and bumps - critical for gear you'll haul to dark - sky sites.

Locking Screw: Zero Gaps, Zero Light Leak

A locking screw mechanism tightens the drawer to your camera/lens, closing gaps that let unwanted light seep in. For long exposures (e.g., capturing faint galaxies), this means no “glow” or artifacts. It's a tiny tweak that saves you hours of post - processing headaches.

Dual Filter Holders: Fast Swaps in the Dark

The SV226 M54's dual, plug - and - play holders let you switch between broadband (LRGB) and narrowband (Hα/OⅢ) filters in seconds. Whether chasing nebula colors or cutting through light pollution, adapt on the fly without disrupting your workflow. And here's the kicker: getting a drawer that comes with two 2 - inch holders for just $65.99!

Why It Works with Full - Frame Cameras

Full - frame sensors demand gear that maximizes their potential - no vignetting, no light leaks, no compromises. The SV226 M54 checks every box:

• M54 threading locks securely to cameras/lenses (dedicated astro or modified DSLRs).
  Filter coverage (2 - inch standard) matches full - frame sensor size, so edges stay bright.
  Light control (locking screw + anti - glare coating) ensures your sensor captures pure, undistorted data.

Pair with SV555 Astrograph

The SV555's wide-ield, full-frame optics pair seamlessly with this filter drawer. 

• Speed up your workflow (fast filter swaps, secure locking) so you focus on framing shots, not fixing gear.
  Scale with your setup - add new filters, swap cameras, and keep shooting without rebuilds.
