Highlight of the new Antlia LRGB V PRO 2", Mounted

• Improved contrast, star hypertrophy, and halo minimization compared with the previous Antlia LRGB V-series
• Premium coating technology and finely polished substrate Our quality selection processes are optimized to ensure highly homogeneous glass-substrates. Our application of advanced optical coating technology and double-sided precision polishing achieves both consistent parfocal and optical performance across all filters.
• Maximized colour balance and contrast for each of the three RGB channels and excellent S/N performance Dozens of coating layers are deposited on both sides of the glass substrate that enables LRGB-V Pro filters to achieve a high SNR. The Anti reflection coatings and carefully designed spectral gaps minimize unwanted light scatter and maximize useful signal data for each filter channel.
• Tighter star profiles and halo reduction The cut-off rate of LRGB-V Pro series set is designed in high level to minimize halos around brighter stars and reduce star bloat. Our careful design of the blue channel transmission characteristics targets the problem of blue star bloating.
