3. 更紧密的星体轮廓和减少光晕 LRGB-V Pro系列套装的截止率经过高级设计，可最大限度地减少明亮星体周围的光晕并减少星体膨胀。我们精心设计的蓝色通道传输特性针对的是蓝色星体膨胀问题。

用途与性能：

1. 专为单色CCD和CMOS相机设计

2. 天体、星系、星团和星云的出色成像色彩

3. AR增透膜设计，减少二次反射和星晕

4. R-Filter 提供最大程度的 H-alpha 和 S II 发射传输

5. B/G 重叠使 OIII 线的能量加倍

6. 平衡的 RGB 设计为大多数望远镜光学系统提供 1:1:1 的曝光时间

7. 所有 Antlia LRGB-V Pro 滤镜的边缘均经过涂黑处理，以消除杂散光的内部反射

8. 四个 LRGB 滤光片的基板厚度均保持严格的公差

9. 不推荐用于太阳观测和成像

10. 不建议目视观察

重要提示：使用任何共焦滤光片时，用户在长时间成像过程中仍可能会遇到滤光片之间的焦点偏移。重要的是要记住，由于望远镜筒和玻璃光学元件之间的差异收缩，温度变化会改变光路的长度。建议摄影师每 1 到 2 小时手动或自动在软件中检查一次焦点。如果将望远镜从温暖的环境带到室外，则需要更频繁地检查焦点，直到设备稳定在接近环境温度为止。

Ar III Standalone Filter
The Ar III (Argon III) filter is a narrowband filter centered around 713nm, designed to capture the specific emission line of triply ionized argon. This emission line is commonly observed in planetary nebulae, H II regions, emission-line galaxies, and in the spectroscopy of ionized gases in laboratory plasmas. 

Optolong LRGB filter set is designed for maximum contrast and with extremely high gradients for clear differentiation of colors. The LRGB filter set divides the spectrum into its components red, green, blue and luminance.

OIII emission overlaps on blue and green filters with maximum transmission to allow high efficiency and natural color imaging. Gap between green and red filters serves to block out the primary Sodium light pollution line at 589nm and improves color balance and separation.
