ZWO F/W
Tuesday, 5 March 2019  | 

This Filterable proved an Ideal replacement for my old Atik Unit. I could not get a driver to install. Even Atik support had no solution. Perhaps Windows 10 could not accommodate the device.
However, the ZWO was a joy to install, it took about five minutes, and job done.
The price was pleasing too, I only needed a 5 filter one, and this little fellow suited both my requirement, and my wallet.
Thanks to FirstLightOptics too for a great service too.
Staff always ready to advise.

Good quality product

The filter wheel is perfect for narrowband filters, very smooth on the filters switch, and very well done !. Very solid aluminum, ! the only problem is! , if same filters have more them 3mm high , the filter wheel will don’t work becouse the filters wheel will be stuck and do not change filters , in my case : I buy from China a UHC for my small light aberration, was a nice filter but dint fit , , my new choice was Astronomik filters and perfect choice , Ps: ty FLO and crew for the advices and support ,

ZWO Mini EFW Simplicity
Wednesday, 31 January 2018  | 

The aim was to get a smaller more compact and lighter FW for a protable setup. As always, FLO gave great advice and even pulled out all the stops to get my order out right at the last min for next day delivery.

Easy to setup. Comes with a T2-T2 male to male adaptor to connect non ZWO cameras. Downloaded the ASCOM driver and it was recognized immediately. I was up and working in a matter of mins.

For those who want a small lightweight EFW, then i would certainly recommend this.
