Alpine Astronomical Baader Canon EOS Wide T-Ring System with Nebula Filter

Engineered to take advantage of today's larger camera sensors, the Alpine Astronomical Baader Canon EOS Wide T-Ring System eliminates the vignetting that is common when using conventional T-rings, especially on faster systems. The modular design enables the use of an array of Baader 2" mounted or 50.4mm unmounted specialty filters such as O-III, H-alpha, luminance, or neutral density. It comes with three mounting options: a standard 42mm T-thread for conventional T-mount attachment, a low-profile 2" nosepiece to fit into diagonals and visual backs, and a standard 48mm astronomical filter thread. This system is specifically designed to match the Canon EOS bayonet mount. The T-ring assembly comes with a 50.4mm round unmounted nebula filter that yields ultra-high contrast when viewing or imaging nebulae. By its nature, the filter has natural light pollution filtration, helping to eliminate emissions from street lights and improving imaging in most urban areas.
