      5.0 ZWO 5 position electronic filter wheel for 1.25" filters

      Pros:

      Comments:

      The EFW from ZWO is an excellent addition to an astro imaging setup for your monochrome camera. It works seemlessly with my ZWO ASI camera and capture software. AgenaAstro provides great service and fast shipping.

      Works perfectly with Sharpcap and my asi294mc pro! The only thing I will mention is make sure you place the paper spacers so extension tubes etc. do not bind.

      Compared to any other astronomy supply company Agena is simply the fastest. Opt, Highpoint scientific, cloudbreak and Orion nothing is close. They must ship immediately upon order. I receive items by USPS next day.

      5.0 Works!

      Pros:

      Cons:

      Comments:

      The two filter wheels I bought did just what I wanted and I have adapted them to my setup -- with a bit of machining. Not their fault.

      I have a very constrained setup but was able to put two of these wheels in front of a CMOS camera and get it all to work. My problem was machining. After that was done: it all worked.
