Askar's electronic focusing hardware in one place: the WAF worm-and-gear automatic focuser, and the AF kits that adapt individual Askar telescopes to an electronic focus motor.
The two are different things. The WAF is a self-contained drive unit with its own worm-and-gear reduction, power and data ports, and ASCOM Alpaca and INDIGO support. An AF Kit is adapter hardware — bracket, belt and pulleys sized for one specific tube — and the motor itself is bought separately unless the product page says otherwise.
Each AF kit is matched to a single telescope model, so the SQA55 kit fits the SQA55 and nothing else. If you are not certain which one suits your Askar, send us the model and we will confirm it before you order.
