AFW

I wanted to like this product but I have been having issues. It randomly and unexpectedly starts to spin infinitely at NINA command to change filter. Like I mentioned, this behavior is random and I cannot narrow it down to a specific pattern. It works for a couple nights and then suddenly this happens. I tried with different USB cables as well as connecting directly to the camera hub or to the computer but the issue keeps happening in both cases so It must be the AFW itself. Needless to say how frustrating this is since I missed quite a few nights session because of this issue. I cannot use it any more and I cannot work with an unreliable product. I sent TOuptek an email for a solution either hardware wise or firmware wise. Otherwise refund/return option (perhaps I got a bad sample but I found forums where other people are having same issue).

Perfect :)

Works well , high quality. Disadvantage : Baader Filter ,even low profile ,do not fit.

I am very happy with the filterwheel, easy to install at NINA and building is very good. Nice piece of work and super fast shipping.THX ToupTek
