ZWO quietly released an updated version of their Electronic Filter Wheel (EFW) and at first glance it looks almost the same. But once you put it side by side with the previous model, there are actually quite a few differences.
In this video, I compare the new ZWO EFW to the old version and walk you through every change I could find, from the design and mechanics to the practical details that matter in real-world astrophotography setups.
Some of the improvements are surprisingly great and might actually be worth the upgrade, depending on your gear and workflow.
If you’re currently using an older EFW, or you’re about to buy one, this comparison will help you make the right decision.
