With \u003cstrong\u003e7 slots for unmounted 36 mm filters\u003c\/strong\u003e, it enables automatic switching through a complete LRGB and narrowband sequence — Ha, SII, OIII — in a single session, without touching the optics and without losing focus. Powered and controlled directly via the \u003cstrong\u003ebuilt-in USB-C hub of the ASI camera\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003e7 positions: maximum flexibility for narrowband imaging\u003c\/h3\u003e\n\u003cp\u003eWith 7 slots, LRGB, Ha, SII and OIII filters can all be loaded at once — the full combination for SHO and LRGB imaging — without ever opening the optical train. The high-precision \u003cstrong\u003estepper motor\u003c\/strong\u003e reaches each position repeatably and silently. 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 telescope-side and camera-side connections are \u003cstrong\u003eT2 (M42×0.75)\u003c\/strong\u003e.
