At just over 4 inches in diameter and a few inches thick (IMX585), the new miniCAM8 is a compact, high-resolution, high-performance, cooled imaging system capable of exceptional, high-quality deep space images as well as high-quality, high-resolution planetary images.

So often, compactness in astroimaging is achieved at the expense of some other critical feature found in multi-component cooled systems, such as sensor quality or thermoelectric cooling, etc. Such is not the case with the new miniCAM8. Based on Sony’s IMX585 8 MP sensor, the miniCAM8 includes full TE cooling capable of reaching a delta of -45℃ from ambient along with a built-in 8-position filter wheel for complete LRGB and narrowband imaging.

High Near-Infrared Sensitivity

The IMX585 is a Sony Starvis II processor that enables high sensitivity and high dynamic range (HDR). It also improves sensitivity in the near-infrared range by approximately 1.7 times* compared to the IMX485. The new camera miniCAM8 has a maximum quantum efficiency of 60% in the near-infrared band and 92% in the visible wavelength band.

BSI

One benefit of the back-illuminated CMOS structure is improved full-well capacity. This is particularly helpful for sensors with small pixels. In a typical front-illuminated sensor, photons from the target entering the photosensitive layer of the sensor must first pass through the metal wiring that is embedded just above the photosensitive layer. The wiring structure reflects some of the photons and reduces the efficiency of the sensor.

In the back-illuminated sensor, the light is allowed to enter the photosensitive surface from the reverse side. In this case, the sensor’s embedded wiring structure is below the photosensitive layer. As a result, more incoming photons strike the photosensitive layer, and more electrons are generated and captured in the pixel well. This ratio of photon to electron production is called quantum efficiency. The higher the quantum efficiency, the more efficient the sensor is at converting photons to electrons, and hence the more sensitive the sensor is to capturing an image of something dim.

Zero Amplify Glow

miniCAM8 is also a zero amplifier glow camera.

Anti-Dew Technology

Based on almost 20-year cooled camera design experience, the QHY cooled camera has implemented the fully dew control solutions. The optic window has a built-in dew heater, and the chamber is protected from internal humidity condensation. An electric heating board for the chamber window can prevent the formation of dew, and the sensor itself is kept dry with our silicon gel tube socket design for control of humidity within the sensor chamber.

Cooling

In addition to dual-stage TE cooling, QHYCCD implements proprietary technology in hardware to control the dark current noise.

Filters

The astronomical filters included with the miniCAM8 deepsky combos are custom-designed to match the specific characteristics of the cameras. The size is 19 mm * 12 mm * 1.1 mm. The LRGB and SHO narrowband filters for the miniCAM8M deepsky combo are customized by XiMei Filters. The LRGB filters have an optical density (OD) value of 3, while the narrowband filters have an OD value of 5.

Antlia ALP-T 双波段 5nm 高速滤镜经过优化，可通过略微移动通带和中心波长来配合高速成像系统使用。与标准版本相比，在 f/2.2 和 f/3.6 光学器件之间使用这些高速滤镜，在星云成像中显示出更强大、对比度更高的效果，如果您希望使用任何比 f/2.2 更快的光学器件获得最佳性能，高速版本是最佳选择。

但请记住，计算机模拟的蓝移数据表明，窄带滤光片会将其带宽移至更短的波长，光学速度快于 f/2，发射波长的透射率可能会降低 15%-20%。虽然 Antlia ALP-T 高速滤光片在快速光学器件上使用时，Ha 和 OIII 的透射率也有类似的降低，但根据当前标准版用户的数据，很明显，该滤光片仍然具有增加发射星云对比度和最小化光晕的高性能。

高速版本价格与标准滤光片相同，为高速光学用户带来双重好处。值得一提的是，Antlia 使用 Agilent Cary 的专业分光光度计逐件检查和测量产品，分辨率/狭缝宽度高达 0.2nm，这使我们能够为您提供高度可靠和一致的产品。

Antlia ALP-T 双波段 5nm 系列滤光片是一种双线通滤光片，主要用于单次拍摄彩色 (OSC) 相机，例如 DSLR 和天文 OSC 相机。它还可以用作单色相机的窄带滤光片，以节省成像时间。我们的 ALP-T 超双波段滤光片上的高级多层镀膜可有效隔离发射星云的红色 Ha 和蓝绿色 OIII 线光，几乎完全抑制光污染、月光和气辉中不需要的波长的光密度 (OD)4.5。因此，我们的 ALP-T 双波段 5nm 滤光片可为您的图像提供出色的信噪比和更好的对比度。

该滤光片可以同时捕捉两个主要发射星云带，同时抑制不必要的光污染。它可以让您捕捉到更清晰的数据，并减少后期处理工作量，以便将微弱的细节与背景光污染隔离开来。

用途与性能：

专为快速天文光学设计，特别是 f/2.2 至 f/3.6 比率

专为与 DSLR、CMOS 和 CCD 彩色相机配合使用而设计

抑制不需要的波长的光密度 (OD)4.5 可增加信噪比

SBIG StarChaser SC-2 离轴引导相机

Diffraction Limited 的新款 SBIG StarChaser SC-2 是世界上第一台支持自适应光学技术的一体式独立离轴导星相机。StarChaser 独立于主相机运行。它结合了拾取镜、导星相机、导星口和自适应光学控制。

不要再因为主相机和导向器之间的弯曲而导致曝光失败而浪费时间。离轴导向通过对主相机和导向器使用相同的光路消除了这个问题。

大多数离轴导向器组件使用起来很不方便，占用太多后焦距，并且需要通过将相机滑入目镜支架内来进行对焦。SBIG 率先推出了简化的离轴导向器，将导向传感器内置在 CCD 相机中。后来，我们创造了自导式滤光轮，将导向传感器放置在光子掠夺窄带滤光片前方的光路中。StarChaser 是这一进程的下一步 - 一款具有 AO 功能的完全独立的导向相机。

注意：当使用 StarChaser 和 AO 时，您需要StarChaser 到 AO-X/AO-8T 适配器电缆。必要的适配器电缆包含在我们的StarChaser SC-3 / AO-X 套装和StarChaser SC-2 / AO-8A 套装中。

三种版本可供选择

StarChaserSC-2 专为与我们的紧凑型 SBIG 相机配合使用而设计。它支持AO-8A自适应光学单元。请参阅下表以了解与各种相机型号的兼容性。

适配器也可用于将 StarChaser 连接至旧式 STL 相机。对于具有较小传感器和内部滤光轮的 STL 相机，您可以使用带有适当适配器的SC-2。另一个适配器可用于连接 SC-3-SHORT，适用于具有较大传感器和外部滤光轮的 STL 相机。

下一代离轴导引

StarChaser 代表了我们新一代的离轴导向技术。它采用高灵敏度的 130 万像素全局快门 CMOS 传感器，像素大小为 4.8 微米。与同类自动导向器不同，StarChaser 配有机械快门，可轻松进行暗框校正。此功能是所有 SBIG 导向器的标准配置，可优化灵敏度并消除可能降低导向精度的热像素。

可通过松开锁定旋钮并将镜子滑入或滑出外壳来调整拾取镜位置。您可以避免主传感器产生晕影，同时优化进入导向传感器的光路。设置完成后，只需转动第二个旋钮即可调整焦点。

自适应光学控制

得益于 SBIG StarChaser 系列，我们著名的自适应光学 (AO) 技术现在几乎可用于我们整个相机系列！我们的 AO-8A（单独提供）用螺栓固定在 StarChaser SC-2 的前面。StarChaser 则安装在 SBIG 标准滤光轮和相机的前面。

自适应光学技术可消除常见的安装问题（如静摩擦、周期性误差和风荷载）导致的引导误差。它甚至可以减少“视差”效应，从而获得更高分辨率的图像。

轻薄且适应性强

STarChaser StarChase ST-2 SC-2 厚度仅为 0.800 英寸（20.3 毫米）。当连接到滤光轮时，现有的适配器板（厚度为 0.147 英寸/3.7 毫米）通常会从滤光轮移到 SC-2 的前面。当将 AO-8A 连接到 SC-2 的前面时，无需使用适配器板。
