ZWO Filter Wheels & Accessories

ZWO filter wheels and accessories cover every way of changing filters in a ZWO imaging train. EFW electronic wheels come in 5 x 1.25", 8 x 1.25", 7 x 36mm, 5 x 2", 7 x 2" and 7 x 50mm square versions, and a manual 5 x 1.25" wheel suits simple setups.

For one filter at a time, M54 and M42 filter drawers and EOS or Nikon lens drawers slide into the train. Filter holders, a 2" to 1.25" ring and a T2-1.25" adapter complete the range.
