This is easy enough to fit. You need to use the original nuts and bolts, so don't lose them and don't let them fall down onto the mirror. The original signal speed focusser was very easy to knock out of focus accidentally, and even tightening the locking screw seemed to throw it slightly out. This dual speed one holds its position even without locking and you can easily get sharp focus using the fine adjustor. I've found it useful getting precise focus when changing lenses that are billed as par focal but in practice need a slight adjustment.

While enjoying the planets & stars , the view for me just wasn't I felt as sharp as it could be. Now that I have received & fitted the dual speed eye piece what s difference. From the Moon to early January looking at Jupiter all I can say is OMG what clear views & sharp.

A replacement for the 200P that comes with a single speed focuser, this makes such a difference, well worth it and easy to fit
Dual speed Crayford focuser

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”
