ZWO EFW new design for 2026 just arrived


Tuesday, December 9, 2025 by

ZWO has released a refresh of its staple electronic filter wheel. At first glance it looks much like the version many astrophotographers already use, which appears to be the intention.

Astronomy Picture of the Day

Hello World
Hello World - 2026-04-04 - NASA Astronomy Picture of the Day
From pole to pole our fair planet is captured in this snapshot from space, an evocative image from a window of the Orion spacecraft Integrity. From the spacecraft's perspective the Sun is moving behind Earth's bright limb along the lower right. Africa and the Iberian peninsula are in view on the pale blue planet's surface, while aurorae crown Earth's south and north poles at top right and bottom left. Commander Reid Wiseman took the historic picture on Artemis II mission flight day 2 (April 2), after the completion of the planned translunar injection burn. That burn boosted the spacecraft out of Earth orbit, sending Integrity and crew on a trajectory that will take them around the Moon and back again. That's a journey humans last made over 50 years ago.
