The Next-Generation ZWO EFW

Refinded Design · Anti Light-Leak Protection · Built for Astrophotography
A re-engineered internal design helps reduce light leakage, while the refined mechanics deliver smoother, more consistent rotation.

The exterior has been subtly streamlined, giving the wheel a cleaner and more cohesive look.
Nothing dramatic. Just better in the ways that matter — so your imaging workflow stays steady, reliable, and quietly improved.

OAG-L has a large prism size of 12*12mm, far bigger than M68 OAG. The bigger clear aperture brings wider field of view in guiding. It is easy to use, and suitable for users who are interested in long focal length photography.

To take the most advantage of it, we recommend you to match it with large format guiding cameras.

ฟิลเตอร์ SVBONY Dark Filterสำหรับถ่าย Dark Frames บนกล้อง CCD, 2"

• Quickly capture dark frames to optimize photo quality
• Opaque - blocks all light from the imaging camera sensor. Help remove dark currents - essential for astrophotography
• Easily eliminate camera noise and hot pixels
• Dark frame acquisition helps remedy such noise and "hot pixels" by canceling out these disruptive effects during image processing
• Threaded and can be directly connected to your filter wheelfor fast conversion between different filters;
• Made of metal for durability. High quality packing box includes foam-lined plastic case

ASI2600MC Duo

The ASI2600MC Duo combines imaging and guiding sensor in one compact body. The main sensor is the Sony IMX571 coming with a native 16bit ADC, 14stops dynamic range and 3.76um square pixel array. The readout noise is as low as 1.0e, and the full well capacity reaches an incredible level of 73ke. And it has no amp glow!

The guide sensor is the Type 1/1.8 SC2210 with excellent NIR sensitivity. The sensor size is 7.68mm x 4.32mm. It has 4umx4um pixels with an array of 1920x1080 and a full depth of 8780e.

The stars on the corner of the guide images affected by reducers back focus distance might not be very round. It is not due to the sensor tilt and will not affect normal use.

Optolong L-Synergy dual-narrow band filter FWHM7nm

Optolong L-Synergy‌ is a dual 7nm narrowband filter compatible with DSLR cameras, color CMOS sensors, and CCD cameras, supporting telescope systems with F-ratio of F3.3 or above (slower system）. Its key advantage lies in enabling astrophotography amateurs to capture exceptionally detailed emission nebulae even in light-polluted environments. it has been optimized to minimize bright star halos while isolating all emission lines except SII and OIII, achieving maximum effective transmission.
