letting through light only where optics are their sharpest (especially with refractors)

Today’s electronic performance (such as very low CCD resolutions and increasing optics performance) force instrument manufacturers to improve every detail of every mechanical part: the tripod is the base of the setup and it needs to be perfect with torsions

ANTLIA 4.5nm EDGE NARROWBAND SHO SET Cable it is not recommended forThe Antlia 4. 5nm Edge H Alpha, Oxygen III & Sulphur II narrowband filters have the same excellent transmittance characteristics as their 3nm Pro series but at a more affordable price. The 4. 5 nm bandpass is only 1. 5% of the entire visible spectrum, increasing the signal to noise ratio and delivering high contrast images and extremely dark backgrounds. To even further enhance the contrast, and suppress the stray light and internal reflections,
