William Optics Saddle Plate for Vixen-style Dovetail Plate - 90mm (Red)

1/3"size 1280X960 @30fps Mono USB2.0

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.

SvBony SV172 Dew Heater for Telescopes and Camera Lens, 240mm

• Designed for astronomy telescopes and cameras, protecting optical devices like telescopes and cameras from fogging or freezing
• Prevents dew condensation from forming on the glass surface
• Provides even heat distribution. Power-efficient design will not result in an extra drain on your power supply.
• Three-speed regulator strong-medium-weak heating modes, you can adjust the temperature in different situations
• Width of the 50mm narrow width design, will not block your field of view and will not have dark corners in the field
• Great heat preservation effect: Imitating OK cloth, SBR and Black-T three-layer keep warm material fits the lens better, fast and even heating
• Alloy fiber heating wire provides super fast and continuous warming, silicone insulation process can prevent internal short circuit
• Measure the circumference of the telescope tube or camera lens (or measure the tube diameter - not the scope aperture - ×3.14). Compatible with OD of telescopes/lenses below 76mm

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
