Sky-Watcher Auto Focuser
Tuesday, 10 December 2019  | 

I bought this to drive a low profile Skywatcher focuser recently added to replace the original high profile focuser on my 250 mm Synscan dobsonian. Although the steel base plates that come with the auto focuser are not designed to marry up with this particular focuser it was easy enough to make it all work by drilling two more holes in the plate and finding suitable bolts and washers to keep every thing straight and aligned. Worked well and, combined with the focuser upgrade, proved a very cost-effective route to enabling EEA on the Synscan. One watchout is that to revert to manual focusing (say when the 9v battery runs out) - the electric drive needs first to be disengaged by the somewhat inconvenient means of using a hex key to loosen off the grub screw gripping it to the focuser spindle.

Fantastic for DSLR lenses

I have one of these connected to my Samyang 135mm lens and a HiTec Astro DC focuser ( I pasted this review there as well). I bought a 3d Printer toothed wheel and belt so as to connect this motor around the lens. I now have autofocus working brilliantly with my widefield Samyang lens, controlled by SGP. So I am always in focus

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.

Q1. Can you supply a longer cable?
