This ZWO EFWMini was used for the last two years on my astrophotography rig. It is quite excellent and functions great, especially with ZWO astro cameras. It has 5 slots that can fit 1.25" mounted filters or 31 mm unmounted ones. Mounted filters should have a height clearance of less than 7 mm. The wheel is ASCOM-compatible with the ZWO driver available on the company website. It connects through USB. I've used it with ZWO filters but I've since switched to the 8 slots version in which I am also using Baader narrowbands and it works quite well. Assembly thickness is 20 mm. All the accessories in the picture are included within the original box. You can go on ZWO's website for the details. Note that this is the Version 1 of the package. ZWO has updated it to provide locking rings for unmounted filters. Version ! used plastic washers with screw to hold unmounted 31 mm filters.
I accept immediate payment through Paypal only. I will ship to Canada and continental US. US BUYERS: be aware that crossing the border will most probably require additional customs and duty fees that are not included in the price and must be paid at delivery time.
