iOptron iPolar Electronics Polarscope for SkyGuider Pro

Introducing iOptron iPolar^TM - a high precision, easy to use electronics polarscope (e-PS).

What makes iPolar unique?
1. Can be easily installed inside the RA shaft on all iOptron equatorial mounts (except SmartEQ Pro).
2. Can be used on any mounts with adapters either internally or externally.
3. USB plug and play (no driver needed)
4. Works globally, no need to set northern and southern hemisphere.
5. No visible Polaris (north) or Sigma Octantis (south) necessary.
6. No need to rotate the mount during polar align.

iPolar is a smart electronic polarscope for everyone.

Highlight of new Antlia LRGB V PRO 1.25"

• 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.

FF80APO 0.76X Full Frame Reducer

ZWO has released a new 3-inch FF80APO 0.76X full frame reducer with a three-element optical design, including one element made of ED glass. Its reduction factor is 0.76x, which gives the FF80APO f/7.5 astrograph a shortened focal ratio of f/5.7 and a shorter focal length of 312mm. This allows for less total integration time and a wider field of view, bringing more convenience and possibilities for your wide-field deep sky imaging.

The reducer has a rear interface that attaches to the FF80APO telescope tube’s included four-segment camera extension tube. The back focus is the standard 55mm, and it has a built-in M48X0.75 2-inch filter thread for easy attachment.
