Antlia CH4 1.25"

Highlight of the newAntlia LRGB V PRO 31mm, Unmounted

• 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.

กล้องเล้งดาวเหนือ Sky-Watcher Polar Scope for EQ3 / EQM-35 / HEQ5/ CG4

• Suitable for Skywatcher EQ3, EQ3-2, EQM-35 and Celestron CG4 mounts. 
• Improved version with screw connection to mount 
• Precise polar lignment of the mount (for e.g. astrophotography) within a few minutes. 
• For using the polar scope you need an unobstructed view of Polaris. 
• This new version supports the Kochab method, which can easily found in the internet, for showing the correct position of Polaris on the reticle. 
• This polar scope also works on the Southern Hemisphere, by using the position of sigma Octantis

The Sky-Watcher Polar axis finder scope speeds up and refines the polar alignment procedure so the observer can spend more valuable time observing, rather than setting up.
