With \u003cstrong\u003e5 slots for 2\" filters (M48×0.75) or unmounted 50 mm filters\u003c\/strong\u003e, it enables automatic switching through a complete LRGB or narrowband sequence (Ha, SII, OIII) without touching the optics and without losing focus.

Filters sit only \u003cstrong\u003e10 mm from the sensor\u003c\/strong\u003e, eliminating vignetting even with fast telescopes.\u003c\/p\u003e\n\n\u003ch3\u003eT2 connection and native ASIAIR integration\u003c\/h3\u003e\n\u003cp\u003eBoth connections are \u003cstrong\u003eT2 (M42×0.75)\u003c\/strong\u003e.
