What is the advantage of the Askar SQA55 Autofocus Kit over a standard EAF adapter?
The Askar SQA55 AF Kit offers three key advantages. First, its tensioner pulley tightens the belt for higher focusing accuracy. Second, its compact adapter plates are specifically designed to avoid interference with cameras and other accessories. Finally, its modular design allows the entire assembly to be installed in different positions on the SQA55, freeing up space where you need it most.
What is focusing backlash and how does the Askar SQA55 AF Kit reduce it?
Backlash is a slight lag or "slop" in a mechanical system, often caused by a loose drive belt. In focusing, it means the focuser doesn't move immediately or precisely when the motor turns, leading to inaccurate results. The SQA55 AF Kit addresses this with a tensioner pulley that lets you adjust the belt to a tight state, which improves focusing accuracy.
Can I use the Askar SQA55 Autofocus Kit with a Pegasus Astro Cube or other large EAF?
Yes. The kit is designed for broad compatibility with focusers that may have non-standard hole spacing. The L-shaped adapter plates have a hollow design. To adjust for a wider focuser body, you can loosen the M4x12mm fixing screws, flip the plates, adjust the spacing to the correct position, and retighten the screws to lock them in place.
I use a full-frame camera and filter wheel on my Askar SQA55. Will this kit get in the way?
This kit is specifically designed to prevent this problem. Unlike many oversized stock mounting plates, the Askar SQA55 AF Kit is compact. Furthermore, you can mount the entire focuser assembly in different positions on the SQA55 lens tube to ensure it does not interfere with your specific imaging train configuration.
Why does the Askar SQA55 Autofocus Kit include 4 different MXL belts?
Different brands and models of electronic focusers use different sized drive pulleys and have varying mounting dimensions. Including 4 belts of different lengths ensures that you will have the correct size to achieve a perfect fit with your specific electronic focuser, eliminating the need to source a custom belt separately.
Does the kit include the hardware to attach my electronic focuser to the SQA55?
Yes. It provides a complete set of mounting hardware, including 2 M4×10mm screws, 2 M3×10mm screws, and 2 M4×12mm screws, along with 3 Allen wrenches. The kit can be used with almost all brands of electronic focusers.
