AFW-M

Super pleased with this product, for the same price as a 5x1.25” EFW from ZWO you can get this! I would give it 5 stars however I think 4 stars is more appropriate because it doesn’t come with the brackets to hold 31mm unmounted filters, which is okay for me as I’m using 1.25” filters but for those with 31mm filters it is definitely a inconvenience not to have those come with the AFW

I got my wheel almost as scheduled, but that was due to my country customs. NINA recognized it right away. It came with an updated firmware that solves the LED light leakage. Movement is smooth, if not a bit noisy, but that doesn't bother me. The filters seem to center just fine in both uni or bidirectional settings (no backlash because of the friction drive). I did install a baader filter and it seems to fit just fine (I mention this because of a different comment on this page). The only downside I see with this filter wheel (and I understand why this choice was made) is that the connections are M54. Being a universal 1.25"/36/2" filter wheel, the frame must allow for the biggest filter option. I got the 1.25" version, so that hole seems extremely big. As a suggestion, it would be great if touptek could include a second M54 to T2/M48 adapter, but with a female T2 or M48 thread (since we already have a T2 to M48 adapter included. This could help if you're using a T2 camera/OAG combo (like a ZWO 183/294/533 or an SVbony camera. Also, some masks would be good for the screw holes. 5/5.

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).

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