What is the main purpose of the Askar ACL200 AF Kit?
The Askar ACL200 AF Kit is a mechanical adapter that allows you to attach an electronic focuser, such as the ZWO EAF, to your Askar ACL200 lens. This enables you to achieve precise, automated focus control from a computer, which is essential for modern astrophotography.
Does the Askar ACL200 AF Kit include the ZWO EAF or the lens itself?
No, it does not. This is a critical point. The kit contains only the mechanical hardware (holder, belt, pulley, screws, dovetail plate) required to connect a focuser to the lens. The Askar ACL200 lens and the ZWO EAF (or any other electronic focuser) must be purchased separately.
What electronic focusers are compatible with the Askar ACL200 AF Kit?
The kit is specifically designed for a seamless fit with the popular ZWO EAF. However, its design may allow it to work with other electronic focusers that share a similar form factor and shaft size, though compatibility is not guaranteed with other brands.
How does the Askar ACL200 AF Kit attach to a telescope mount?
The kit includes an Askar Vixen-style dovetail plate. This plate attaches to the bottom of the lens collar and the EAF holder, replacing the original mounting foot. You can then clamp this dovetail plate directly onto any mount equipped with a Vixen-style saddle.
I'm imaging the Andromeda Galaxy (M31) with my ACL200. How does this kit help over a long night?
As ambient temperature drops during the night, the focus of your lens will shift, softening your images. The Askar ACL200 AF Kit, paired with an EAF and software, allows you to run autofocus routines periodically. This automatically corrects the focus, ensuring your stars remain sharp in every sub-exposure, which is crucial for a detailed final image of M31.
Can I use the Askar ACL200 AF Kit on a portable star tracker for wide-field targets like the Rho Ophiuchi cloud complex?
Yes, absolutely. The kit provides a secure Vixen dovetail, which is a standard mounting interface. As long as your star tracker has a Vixen-style saddle, the entire assembly (lens, camera, and AF kit) will mount securely, allowing you to benefit from automated focusing even with a lightweight, portable setup.
