Cytron Japan Comet BP Band Pass American Size SY0099A Filter+ (Comet Filter)

【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. Transmits the emission lines of comets It transmits the wavelength range near the four main emission lines of celestial bodies, Hα, Hβ, OIII, and SII, and also transmits the emission lines near CN, C2, and C3 of the comet's core and tail, and cuts out other wavelengths, making comets and nebulae visible even in light-polluted areas. Uses synthetic quartz glass with reliable domestic quality.Multilayer films are deposited on both sides of the highly precisely polished synthetic quartz glass base using IAD (ion assisted deposition) coating by a major Japanese vapor deposition manufacturer. The membrane surface boasts high density, homogeneity, and stability.

The American size uses a newly designed large-diameter filter frame, which is less prone to vignetting than our conventional frames. Note: *It may not be possible to install depending on the telescope or lens. *The characteristics of this product depend on the incident angle of the light beam. To ensure proper performance, we recommend using it with a telephoto lens or telescope. When using a wide-angle lens, the brightness and color balance will be uneven on the screen. *Please use commercially available image processing software to adjust the color balance of the images you have taken. *Product specifications may change without notice. Thank you for your understanding.
