  • SII+OIII & Hα+OIII : Colour Magic C2 Duo-band filter (SII+OIII) has a high transmittance of over 90% at its center wavelength (500.7nm and 672nm). Colour Magic C1 Duo-band filter (Hα+OIII) has a high transmittance of over 90% at its center wavelength (500.7nm and 656.6nm),It can effectively improve the quality of the image by making the sky background of the image darker while maximizing the contrast throughout the image, enhancing the contrast of your pictures, and making it easier to display the details of the stars.
  • ASTROPHOTOGRAPHY: This filter can improve the contrast when observing gaseous nebulae and planetary nebulae under any sky conditions,even in places with light pollution, high contrast observation effects can be achieved
  • LIGHT POLLUTION REDUCTION: Telescope astronomy filters can effectively reduce the interference of artificial light pollution such as city lights, natural light sources or street lights, facilitating better observation,this filter can also selectively filter light pollution and cluttered signals through the emission lights of the nebula to achieve the ideal shooting effect.
  • EASY TO USE: Dual-band filters can completely blocks virtually all other visible wavelengths of light so views of nebulas are optimized and reduce the difficulty and tediousness of user post-processing, reducing the difficulty for customers to get started
  • BETTER IMAGE: After using this filter, it can produce an extremely clear and sharp effect image, so this narrow band filter is considered one of the most popular astronomical accessories. It can be used not only for astronomical observation, but also for astronomical photography.

Llueve sin parar desde que me llegaron, no los he podido probar.Muy bien envueltos (en su cajita de plástico, dentro de sus cajitas de cartón, dentro de la caja de cartón del kit, dentro de una caja de cartón con el interior forrado, dentro de una bolsa plastificada y acolchada).Cuidado:He comprado un producto, los filtros, cuyo anuncio dice que incluye el IVA (lo cual implicaría estar comprando en la UE) y luego me encuentro que tengo que pagar gastos de aduana para poder obtener el paquete.

L’oggetto è arrivato dopo 10 giorni dall’acquisto, perfettamente imballato e tramite corriere. Per adesso ho provato solo il filtro C1 (narrowband Ha - Oiii) ed il risultato parla da solo: con tre ore di esposizione si riesce a fotografare la Nebulosa di Rosetta da Milano con un cielo molto inquinato!
