iOptron iPolar Electronics Polarscope for SkyGuider Pro
Introducing iOptron iPolarTM - a high precision, easy to use electronics polarscope (e-PS).
What makes iPolar unique? 1. Can be easily installed inside the RA shaft on all iOptron equatorial mounts (except SmartEQ Pro). 2. Can be used on any mounts with adapters either internally or externally. 3. USB plug and play (no driver needed) 4. Works globally, no need to set northern and southern hemisphere. 5. No visible Polaris (north) or Sigma Octantis (south) necessary. 6. No need to rotate the mount during polar align.
iPolar is a smart electronic polarscope for everyone.
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, 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
The L-Ultimate is a 3nm dual band filter designed to drastically reduce the effect of light pollution. The 3nm isolates the nebulae's emissions into H-Alpha (red) and OIII (green-blue). It blocks light pollution, maximizes the signal from nebulae, and darkens the sky background. It also blocks artificial light from mercury vapor lamps, high and low pressure sodium vapor lights, and unwanted natural light caused by the emission of neutral oxygen in our atmosphere, maximizing the transmission of the main emission lines of the nebula in OIII (496nm and 500nm) and H-alpha (656nm). Used with DSLR, color/MONO CMOS and CCD, this filter is suitable for telescopes with an f-ratio of f/4 or higher (slower).
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.
Excellent Ha filter, installed it in a ZWO filter wheel and tried it on the evening just after receiving it and got great captures of the Dumbbell planetary nebula, very sharp and detailed. Thanks to Thaiexcite who shipped it quickly, so I was able to use it on that clear sky night!
