新一批IDAS光學濾鏡經已於近日抵港。IDAS LPS-D3 48mm 光害濾鏡抑制人工照明(特別是 LED 照明)所產生的常見發射線,同時允許星雲發射線通過,從而增強天文物體或星雲的對比度。

IDAS NBZ UHS 雙波段星雲增強濾光片 48mm 是一種新型雙窄帶濾光片,旨在增強 Ha 和 OIII 發射星雲的對比度。它旨在減少 NBX 的內部反射,並在與快速光學系統一起使用時適應光譜偏移,特別針對f/2水平的如Celestron RASA或Starizona HyperStar系統而優化。

A new batch of IDAS optical filters has arrived in Hong Kong recently. IDAS LPS-D3 Light Pollution Filter 48mm suppress the common emission lines generated by artificial lighting, particularly LED lighting, while allowing the nebula emission lines to pass. The contrast of astronomical objects or nebulae is therefore enhanced.

IDAS NBZ UHS Dual Band Nebula Boost Filter 48mm is a new dual narrowband filter designed to enhance the contrast of Ha and OIII emission nebula. It aims to reduce internal reflection of NBX and accommodate the spectral shift when used with fast optical systems, specially optimized for f/2 optical system like Celestron RASA or Starizona HyperStar system.
