When every millimeter matters, the Ultra-Short T2 Adapter for Canon DSLRs offers the precise solution for tight-space astrophotography setups. With an incredibly short 1.5 mm light path, this adapter allows you to reach critical focus where standard T-rings (typically 11–12 mm) would fail.
Crafted from durable stainless steel and precision-machined for a rock-solid fit, this low-profile adapter connects your Canon DSLR to accessories with a standard M42x0.75 mm T-thread, making it perfect for use in Newtonian reflectors, astrographs, or any imaging train with strict backfocus requirements.
