I bought the Skywatcher Auto Focuser for my Vixen VC200L tube. I was worried whether it would fit, but it does perfectly. I'm very happy with the product and also with the service FLO provided. Thanks guys!

Great Little Gismo

Fast and efficient service as normal from FLO.
The Auto Focuser was fitted to my SW200P in no time at all with everything lining up and working perfectly and smoothly from the off. Luckily I had a crystal clear night on the day of fitting and was impressed by the Focuser immediately.
As with other reviews the battery compartment was a pain to close and I managed to snap the little clip but mainly due to my heavy handling of it I suspect. Also I agree with the control coil being a bit of a pain at times but overall the Focuser a great addition to my astronomy tools.

Just right.

I found the Sky-Watcher Auto Focuser to be well made, and nicely robust, without being too heavy to upset my telescope balance, which is a 20 year old Vixen VC200L with a 2 inch rack and pinion focuser. The supplied bracket mated easily with the screws on the Vixen focus control, and it was easy to fit the motor onto the focus spindle.

What wasn't so easy was getting the focus knob off, but I used the best fit screwdriver head I could find (Stanley) and leather gardening gloves to give good grip and reduce any screwdriver through the hand effects.

My manual focuser is old, and it slowed the auto focuser motor considerably during part of the travel compared to it's even free running performance. I found that reducing the tension on the telescope focus mechanism while making sure it was still centrally aligned within the drawtube, and lubricating it with a small amount of plumber's silicone grease made the whole travel more even and easier.

The focus motor loved it. The focusing mechanism is now very smooth, with even, low level, motor noise. The motor current has reduced to a steady 22mA at fast setting, whereas before it was using 22mA in the good places and almost 50mA in the bad.

Focusing on planets like Jupiter and Saturn is a joy, no more wobbling planets to see if the focus is right, then trying again.

Yes, the battery is a bit of a fiddle to get into its compartment, but the improvement in time to reach best focus is great.

Ordering from FLO was easy, and the focuser arrived very quickly.

Autofocus
Saturday, 28 April 2018  | 

I originally installed this on my sw200p no problems ,fine focus easily achieved highly recommend reasonably priced ,battery lasts ages ,now fitted to a 200pds though bit of tweaking involved not too much you just need 2x6mm spacers i used two M6 nuts on the bracket to be able to secure allen screw to focus knob spindle. the springy lead i found to get in the way but made up my own longer lead 6 meters (rj10) an inexpensive job and used a white lead easy to see in the dark ,makes focussing so much easier would recommend .

Very easy and quick to install (a YouTube video made sure of that) on a SW 130PDS. I wish it came with instructions though. Come to think of it, it's not even branded. Neither the box or the product had any form of branding.

easy mod
Tuesday, 31 May 2016  | 

fitted the auto focuser in about 10 mins.all the tools apart from a phillips driver are included as are other unneeded parts..nice smooth focus cuts down on shake.downers are the up arrow winds the focuser out and the down arrow moves it in..and to make large focus changes you fight against the motor drive.really nice easy mod..would be nice to run it from a power tank out of the box instead of batteries....recommended
