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.
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
It is designed for light pollution suppression for OSC and Mono cameras. The spectral design selected the most substantial information in the RGB bands, which makes Antlia Triband RGB Ultra Filter possible to shoot over 90% of deep sky objects, in addition to its excellent performance on emission nebula, different from other ultra-narrowband filters, it is able to capture galaxies, reflection nebulae, and star clusters from a Bortle 8 location to Bortle 1 while presenting more balanced RGB colors in your images. Also, it has a broad bandpass designed to cope with faster optics up to the f/2 focal ratio.
