Explore Scientific M48/T2 Adapter
This adapter solves a very specific problem. You have a 2″ filter with an external M48x0.75 thread, and you need to connect it to a camera or imaging device via a T2 interface. The adapter converts an external M48 thread to an internal T2 thread, so the filter works exactly as if it had a T2 thread from the start. A 39 mm clear aperture keeps the light path completely unobstructed.
The adapter is machined from aluminium and weighs just 10 g. It adds virtually no weight or length to your imaging setup - ideal wherever a standard adapter is missing and every gram and millimetre counts.
Who is this adapter for?
This adapter is a practical solution for astrophotographers and visual observers who use 2″ filters with an M48 thread and want to attach them directly to a T2-compatible camera or sensor. It removes the need for additional step rings or workarounds.

Why choose this adapter?
Standard thread adapters do not always cover every combination of filter and camera interface. The Explore Scientific M48/T2 adapter fills exactly this gap. Its minimal size and weight mean it fits into any imaging train without compromise. The 39 mm clear aperture is wide enough for full-frame sensors and ensures no light loss or vignetting.
Typical use cases
- Attaching a 2″ light pollution filter to a DSLR or mirrorless camera with a T2 ring
- Connecting a narrowband filter directly to an astronomy camera
- Building a compact imaging train where space and weight are critical
