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.

ฟอกัสเซอร์ GSO 2" Crayford Focuser สำหรับกล้องสะท้อน (พร้อมฐานยึดความโค้งเหมาะกับกระบอกขนาด 230mm)

This very high quality, single-speed Crayford focuser for reflector telescopes from Guan Sheng Optical (GSO) is a joy to use. You will wonder how you ever lived without it once you install it!  It will greatly aid in achieving precise focus for visual observations and astrophotography and you will experience very smooth and precisely controlled focuser motion with zero backlash and zero image shift.

SvBony SV172 Dew Heater for Telescopes and Camera Lens, 320mm

• 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 101mm

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.

Svbony SV225 Mini Telescope Mount & SV225T Aluminium Tripod

SV225 MINI alt-az mount allows the telescope to move freely in two directions - altitude and azimuth. Altitude is the movement along the vertical axis and azimuth is the movement along the horizontal axis.

The advantage of an alt-az mount is that it's incredibly simple and easy to use. To move your telescope, you just turn the two knobs to adjust the altitude and azimuth angles. This makes it perfect for viewing objects in the night sky.

When buying an alt-az mount, there are several factors to consider. First, you'll want to make sure that the mount can support the weight of your telescope. Second, you'll want to look for a mount that has smooth tracking and accurate positioning for precise star gazing.
