I fitted this to my old (blue) Skywatcher 200P Explorer telescope. Works a treat. Holes aligned perfectly. Just used old screws. I should really have done this years ago. It’s given my old telescope an extra lease of life. Much better control of focus now. I also tried some imaging using my SW coma corrector and ZWO asi2600MC camera. The focuser held the weight fine.

After reading the reviews here, I was a bit concerned about the distance between the screw holes. In fact, on the focuser I received, the hole spacings 86.5 mm lengthwise and 78 mm crosswise to the tube. The same as the original I broke & replaced with this Dual-speed Crayford 1.25/2" for Sky-Watcher Explorer.
I believe that in Europe, Sky-Watcher Explorer series resemble the Celestron Omni series in the Americas.
I ordered this item from Canada. It took exactly 6 days from receiving the shipping confirmation to my front door. Canadian Border Services Agency managed to intercept it & charged federal & provincial VATs (GST/HST and QST) and then they added $9.95 to deliver it to my door. So it cost me an extra $36. But that is NO FAULT of First Light Optics, it's the cost of red tape. All in all, I couldn't be happier to be able to repair my Omni XLT 150 reflector so quickly!

I've an older Skywatcher 200 and this focuser is a straight swap out. So far I've only use it aligning my finder to my OTA as I gave it a bit of a knock last night but I can already tell this two-speed focuser is a huge improvement over the original. I lined up on my usual target which is the top of an electricity pylon about 5 miles distant. Control of the new dual-speed is on a completely different level from that of the original focuser. Fine tuning with the original was a bit hit and miss with a slight twist here and a bit of pressure on the wheel there. Focusing with this replacement is a dream. The two-speed allowed me to quickly focus down to show the individual rings on a pylon insulator without any of the unpredicatlbe nudging I've become used to.

Purchased this as an upgrade to the awful rack & pinion focuser on my Skywatcher 150p Dob. Ordered Thurs afternoon and it arrived Saturday morning. On Sunday I went about replacing the focuser on my Dob only to find that the new Skywatcher focuser is too big at the base to fit the hole in the telescope. I double checked the website and it says it fits my model of scope but it does not.
I would have ok with having to drop new screw holes but didn’t fancy cutting a bigger hole to accommodate the new focuser. Just in case anyone is interested, the hole for the stock focuser is 76mm and the base of the Crayford focuser is 91mm.
I contacted FLO and the were quick to respond and offered a full refund if I return it (which I will)
Great service from FLO but unfortunately misleading info about the product. I felt giving less than 4 stars would have been harsh as the service was great, just a shame the product did not fit.

Looking for an upgrade to my single speed focuser, I came across this product from First Light Optics. Ordering was simple, oversees delivery to the US was quick and the product arrived in perfect condition due to excellent packaging. This dual speed focuser fit perfectly in my Sky-Watcher 300p and it appears to be the exact same type of focuser that comes preinstalled on the larger 14 and 16 inch models. This was a great upgrade and I appreciate the excellent customer service of First Light Optics!

I purchased this focuser for two reasons number one, I wanted a two-speed focuser for my 12-in collapsible skywatcher telescope. The reason number two, I couldn't find a supplier a dealer who could sell me one and guarantee that it would fit my telescope in the states United States.
It arrived here in less than 5 days in excellent condition and well packed. The focuser was a "direct drop in " for my 12" Skywatcher. 4 screws/nuts, a quick collimation and I was looking at Orion using a really nice (smooth as butter) focusing experience.
I also have to add that the help, information and pertinent e-mails I received before and after my purchase was excellent.
Thanks Guys, I'll be back!

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

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!
