My 254mm Skywatcher Dobsonian came with a single speed focuser which I found rather coarse when in use. I had seen a two-speed Crayford on another 150mm optical tube and felt it would improve my ability to focus on objects to allow simple photo imaging. This device was easy to fit following the simple enclosed instructions, making sure of course that I didn't drop the internal nuts!!! After installation, I did a standard collimation to ensure correct alignment.
This is a vast improvement on my old single - speed focuser, highly recommended.
The service from FLO was first class too!

I bought this with my Dobsonian because I wanted the fine tuning focus from the beginning of my astronomy hobby. It fits perfectly, looks great and handles just “fine”
