The New filter Drawer for EOS Lens,26.5mm thickness is independently designed by ZWO and specifically made to match with ASI cooled cameras and EOS lens. You can freely use the 2”mounted filter with it.
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.
กล้องดูดาว Sharpstar Z4 100mm f/5.5 6-Element Apo Astrograph Telescope
Sharpstar Z4 sextuplet refractor with 100mm aperture and f/5.5 focal ratio, ideal for wide-field deep sky imaging
Six-element design ensures flat field across a 36mm image circle, while two ED elements virtually eliminate chromatic aberration
Rotatable 3.4” focuser, M90-M54 and multiple threaded adapters, 2” adapter ring, and 1.25”-2” adapter
Includes mounting rings, Vixen-style dovetail, carrying handle, and hard case
The Sharpstar Z4 astrograph incorporates a six-element optical design to deliver flat fields and sharp, color-free images from edge-to-edge. With a 100mm objective, two ED elements, and “3+3” optical layout, this f/5.6 scope has a focal length of 550mm and it’s ideal for capturing stunning wide-field images of the deep sky over a 36mm (APS-C) image circle.
