As electronically-assisted astronomy becomes more and more popular, many an electronic or computer-commanded device is widely applied in both sky observation and astrophotography.
For the purpose of better catering to our customers’ practical needs, we again upgrade the ACL200 lens, introducing the ACL200 AF kit (AF refers to automatic focusing) to the market. ACL200 AF kit enables users to operate the lens together with ZWO’s EAF (electronic automatic focuser) to realize auto and more accurate focusing.
Components ACL200 AF kit contains several parts:
A black square holder, used to accommodate and support the EAF.
A 20-teeth synchronous pulley
A synchronous belt
An Askar Vixen-style dovetail plate
An M5×10 socket head cap screw
Two M4×10 socket head cap screws
Two M6×8 socket head cap screws
Two M4×10 button head screws
NOTE: the ACL200 lens and ZWO’s EAF appearing in the advertising videos or posters are not included in this kit, they are for demonstration only.
Assembly
First, take the original black dovetail plate off the ACL200 lens. There are one bigger and two smaller screw holes tapped on one side of the EAF holder, corresponding to the three screw holes at the bottom of the ACL200 lens collar.
Connect the ACL200 lens and EAF holder with an M5×10 socket head cap screw and two M4×10 socket head cap screws.
Then, insert the synchronous pulley onto the shaft of EAF and put the EAF with pulley into the holder. Wrap the synchronous belt around ACL200 lens and the pulley.
Adjust and secure the EAF and its holder, then insert two M4×10 button-head screws into the slots carved out on the side of the holder, tighten them with a wrench.
Put the ACL200 lens on the Askar Vixen-style dovetail plate, connect them with two M6×8 socket head cap screws.
Application
First, you must connect EAF and ASIAIR which functions as a compact computer, with WiFi. Power both EAF and ASIAIR. Then you can control the EAF via a dedicated app installed on your iPad or smartphone by simply inputting the numbers.

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.
