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.
William Optics Adjustable reducer flattener Flat73R for Z73
New, dedicated 2" flattener by William Optics optimized for use with their Z73 Zenithstar OTA. Designed for APS-C size or smaller imaging chips (not for use with full-frame cameras).
Features an M63 male thread for a direct threaded connection to the Z73 on the telescope side.
On the camera side, the flattener has a male M48x0.75 thread. You can use your Canon or Nikon DSLR directly with the use of an optional M48 camera-specific T-ring (sold separately). With this, your camera chip will be placed at the correct 55mm working distance.
Note that you cannot use this with the smaller T rings that have a 42mm T thread.
The WO Flat73R also has a female M48x0.75 (2" filter thread) on the inside to which you can attach standard 2" filters. To access this thread, you need to unscrew the telescope adapter portion of this flattener.
A very neat fature of this item is that a rotator/camera angle adjuster is built into the mechanism of this item, making a separate rotator unnecessary.
