Antlia SII 3nm Pro 窄带滤光片将 FWHM（半峰全宽）优化至 3nm 带通。随着带宽变窄，3nm Pro 窄带滤光片通过降低不需要的背景信号来增强发射目标的对比度。Antlia SII 3nm Pro 滤光片旨在在 671.6nm 线上提供 88% 的透射率，为您提供最大信号...

1. L-eXtreme F/2 简介 Optolong L-eXtreme F/2 是一款双波段（500.7 nm 和 656.28 nm，FWHM=7 nm）窄带通滤光片，满足连续变化角度的透射要求。以天文特征谱线（OIII、Ha）为主要透射波长，OIII 和 H-Alpha 星云发射...

它是一种 3nm 双波段，旨在大幅减少光污染的影响，3nm 将星云的辐射隔离为 H-Alpha（红色）和 OIII（绿-蓝）。它可以阻挡光污染，最大化​​星云信号，并使天空背景变暗。它还可以阻挡汞蒸气灯、高压和低压钠蒸气灯的人造光以及由我们大气中的中性氧排放引起的不必要的自然光。最大化星云在 ...

L-四通增强滤镜（L-QEF）是一款用于彩色相机的四通光污染抑制滤镜。它有效地抑制了光污染波长的透射，特别是人工照明（包括汞灯和钠灯）产生的光污染，以及自然天光对拍摄的影响，从而有效地增强了天体的对比度和细节，使物体更加清晰和立体。这款滤镜在提高抗光污染能力的同时，提供了更好的色彩平衡。L-Q...

当您添加此 H-alpha H-beta OIII (Hα-Hβ-OIII) 成像滤镜时，您可以使用 Celestron Origin 欣赏最耀眼的星云景观。此专用滤镜允许发射星云中的光波长高吞吐量，同时阻挡可能降低图像质量和细节的其他波长。结果是明亮、多彩的星云图像，在黑色天空背景下“突出”...
