经过了红外滤镜改装,拍发射星云时透过更多的Ha谱线,发射星云的谱线主要在Ha波段,不改透过率只有10%,改后在95%,发射星云的云气才能完全显现.

佳能EOS单反转换滤镜让你的佳能单反变身一流的深空天文相机。巴德的新单反滤镜代替工厂改正滤镜。这个特别的基板镀有巴德久负盛名的镀膜,成像单元可以获得足量的H-a波长以及最高分辨率(巴德滤镜可以抵消能降低天体分辨率的佳能的相机莫尔滤镜的作用)。巴德单反滤镜的厚度设计是为了改正相机的焦点(注意:巴德滤镜有意设计成比相机滤镜特殊的厚度--那是为了配合有效相机三明治式的滤镜的折射效果)
这款滤镜专为爱好者方便替换相机已有滤镜而设计。注意:为了达到最优效果,我们建议将镀膜层(桃色)那面朝外(FACF-1, II, III)。这个 为400D设计的 FBCF非常纯净,没有任何桃色镀层,也没有任何特殊的方向性要求。

NEW: DSLR Conversion Filters for Canon EOS cameras. Turn your Canon DSLR into a superb deep sky AstroCamera. Baader's new DSLR conversion filters replace the factory correcting filter ("hot mirror"). The special substrate is coated with Baader's renowned coatings. Imagers can now gain full efficiency at H-Alpha wavelengths, and at full resolution (the Baader filter eliminates the Canon factory moire filter, which reduces resolution on astronomical subjects). The thickness of the Baader DSLR filters have been designed to maintain the correct factory focal point (please note: The Baader filter is intentionally of a different thickness than the factory filter - this is required to match the effective index of refraction of the factory 'sandwich' filter).
This filter is intended for amateurs that are comfortable replacing their camera's stock filter. Please Note: For best performance we recommend installing the filter with the coated (pinkish) side facing out (FACF-1, II, III). The FBCF-400D is clear with no pinkish side and does not require any particular orientation. The digital astro eGroup is a great place for advice on how to replace this filter.
