Celestron 8" F/2 RASA - 使用 Celestron 的便携式天文照相仪 8” Rowe-Ackermann Schmidt 天文照相仪 (RASA)，在几秒钟内捕捉壮观的广角深空图像。这款速度极快的 f/2.0 系统是当今彩色天文 CMOS 相机、小型 CCD 相机和无反光镜相机的完美伴侣。得益于其快速焦比和获得专利的光学设计，您可以生成清晰、细致的图像，并且在许多情况下完全无需自动导星器。重量仅为 17 磅，可轻松将您的 8” RASA 运送到最偏远的黑暗天空位置。

RASA Performance 为每个人打造

8 英寸 RASA 是一款成像望远镜，可提供无光学像差的平坦视野，在广阔的视野范围内呈现清晰锐利的星体。它可以捕捉令人惊叹的深空天文图像，而不会遇到长焦距仪器通常带来的挑战，而且成本仅为这些系统的一小部分。

作为 RASA 家族的最新成员，这款 8 英寸版本比备受赞誉的 RASA 11 更加便携且价格实惠，后者于 2014 年推出并广受好评。随着 8 英寸 RASA 加入该系列，更广泛的天文摄影者可以享受 RASA 设计带来的好处。它具有与其“老大哥”RASA 11 相同的许多精心设计的功能，包括集成空气冷却系统、内部滤镜支架和坚固的 CGE 燕尾安装杆。

8” RASA 专为成像而设计，无法用于目视。主焦点焦平面位于光学系统的前部，因此无法容纳传统目镜。

更短的曝光时间和虚拟的“实时”观察

由于它采用 F/2.0 光学系统，成像仪可以使用更短的曝光时间来捕捉微弱物体的细节。当与灵敏的相机和适当的“实时堆叠”软件结合使用时，8 英寸 RASA 可以提供几乎实时的观察体验。即时在计算机上查看图像，这些图像比用肉眼在更大的望远镜中看到的图像更明亮、更详细。

由于可以缩短曝光时间，您的赤道仪无需长时间准确跟踪。8” RASA 相对较短的 400 毫米焦距也减少了赤道仪跟踪需求。在许多情况下，不需要自动导航。这款光学镜筒重量仅为 17 磅，可与各种镜座完美搭配。

超稳定对焦系统

随着 8 英寸 RASA 的推出，Celestron 推出了一种调焦器设计，可在使用天体照相仪进行调焦、旋转或跟踪时减轻主镜的横向移动。调焦比以往更加轻松、准确和稳定。超稳定调焦系统的关键是两组精密轴承，它们在组装过程中经过精确对准和测试，以确保获得最佳效果。

为当今最新相机而打造

与适用于 DSLR 和大型 CCD 相机的大型 RASA 不同，8 英寸型号在设计时考虑了彩色天文 CMOS 相机、小型 CCD 相机和无反光镜相机。该望远镜不适用于标准 DSLR 相机。它针对对角线长达 22 毫米的传感器进行了优化，但对对角线长达 32 毫米的传感器也表现良好。许多无反光镜相机使用的 APS-C 尺寸传感器是不错的选择。42 毫米全画幅传感器也可以使用，但传感器边缘的性能会很差，并且视野照明会降低。此外，我们不建议将 RASA 8 与直径超过 4 英寸的任何相机机身配对。请参阅下表以确定您的相机是否与 RASA 8 兼容。

独特的光学设计

RASA 的光学设计已获得专利（US 2016/0299331 A1）。该设计由施密特校正器、主镜、透镜组和光学窗口组成。透镜组包含 4 个元件，并采用稀土元素。与许多仅在可见光谱（400-700nm）上表现良好的望远镜不同，8 英寸 RASA 的光学元件设计用于在更宽的光谱范围内工作，从 390-800nm。这使得天文物体发出的更多光线能够清晰地聚焦在图像中。

对于许多成像系统，添加一块额外的平板玻璃（例如滤光片）不会改变光学性能。但是，对于像 RASA 这样的超高速光学系统，情况并非如此。我们的工程师通过设计带有可拆卸光学窗口的 RASA 解决了这个问题，因此，如果添加滤光片或相机有自己的光学窗口，您可以保持最佳光学性能。Celestron 提供专为 8 英寸 RASA 设计的光污染成像滤光片，可安装在光学窗口的位置。

所有折射光学表面均镀有 StarBright XLT 涂层，主镜则采用增强型铝涂层。这可确保整个光学系统的高透光率。

与“Hyperstar SCT”系统相比，RASA 8 提供了更好的光学性能和场照明。

Celestron EdgeHD 11 OTA

高清观看宇宙
EdgeHD 是一款消球差、平场施密特-卡塞格林望远镜，可在宽广的视觉和摄影视野范围内产生无像差图像。该光学系统的设计不仅是为了减少离轴恒星彗形像差，还提供了天文摄影品质的平焦平面，一直到视野边缘......

真正的天文照相品质
许多自称是“天体照相仪”的光学设计实际上只能在弯曲的焦平面上产生精确的星星。虽然这对于某些视觉观察来说可能是可以接受的，但当与数码相机的平面芯片传感器一起使用时，星星会在边缘处失焦。EdgeHD 光学器件产生的焦平面比标准施密特-卡塞格林望远镜的平面平整三倍以上，并且比竞争的无彗形设计平整得多。这保证了您可以在当今一些最大的 CCD 芯片上清晰地看到星星。

提高性能
卓越的边缘性能不仅可以创造出更圆、更令人愉悦的星星，而且与同等孔径的望远镜相比，它实际上提高了分辨率和极限星等。EdgeHD 光学系统的每个表面都采用 Celestron 的 StarBright XLT 光学涂层，可为您提供最宽的视觉和摄影光谱范围内的最大光通量。

机械特性
除了 Celestron EdgeHD 11 OTA 优化的光学设计之外，望远镜筒也经过重新设计，以确保您每晚都能最大限度地利用光学元件。

• 镜子离合器- 灵活的张力离合器将镜子固定到位，并在拍摄长时间曝光的天文图像时减少图像偏移。一旦聚焦，灵活的杆就可以将镜子固定到位，而无需对镜子组件施加任何力或压力，使图像保持在目镜（或传感器）的中心。
• 管状通风口- 位于后部电池上的冷却通风口可让热空气从主镜后面排出。每个通风口都配有一个集成的 95 微米微网过滤器，可确保排出暖空气而不会让灰尘进入。
• Fastar 多功能性- EdgeHD 是当今市场上功能最全面的成像望远镜。在其原生 f/10 光圈下，您可以获得捕捉最小深空物体所需的图像比例。添加可选的减焦镜头（为您的 EdgeHD 镜筒尺寸定制设计），您可以增加视野，而不会牺牲光学性能。巴罗镜可为您提供高分辨率行星、月球和太阳成像的附加功能。所有 EdgeHD 光学镜筒均兼容 Fastar，允许移除副镜并更换为第三方镜头配件，以实现超快 f/2 广角成像。

单独测试
每台出厂的 EdgeHD 不仅经过了每个光学元件表面质量的测试，还经过了相机和人造星的测试，以确保成像系统符合我们严格的质量保证。这项“最终验收测试”确认 EdgeHD 将在现场表现出色并提供高质量的天文图像。

Tele Vue NP127is

25 年来，Tele Vue 不断突破 APO 折射镜和目镜的极限，将性能推向公认的巅峰。Tele Vue NP127is 保留了典型的宽视场和行星视觉能力，同时增加了新功能，使成像更加轻松灵活。

Tele Vue 致力于使 NP 系列在光学、机械和功能上尽可能完美，以便对最大 50 毫米对角线的芯片进行成像，而不会影响其近乎理想的视觉操作。

通过将 TeleVue60is 的开发应用到新款 NP127is 中，并超越其成果，其结果不言而喻。

NP127is 保持了其 127mm f/5.2 光学规格，但采用了重新设计的 4 元件光学系统。更大的后透镜组绝对可以最大限度地减少芯片对角线测量的 50mm 以下格式的渐晕。可选的场校正器使新照亮的边缘的角落几乎与场中心一样完美。为了防止限制更大的会聚光锥，调焦器具有 3 英寸前光圈和 2.4 英寸后光圈。

新的镜筒具有可快速从视觉操作切换到成像操作的功能。同时成像相机可以旋转而不改变焦距（只需记住做新的平面！）。它还能够校正任何残余焦平面倾斜，使成像芯片与光路成直角。

成像插入环带有螺纹，可以容纳 Tele Vue 的新型成像系统配件，包括大直径延长管、光学配件以及带有配合螺纹的照相机/CCD 附件。

TeleVue 制造并测试了齿条齿轮调焦器，使其能够承受超过 5 公斤的重量，但仍可通过 10:1 双速齿轮组件（可使用可选数字测微计套件测量）实现极其精细的调焦控制。可选的 Focusmate 驱动器还允许电动控制调焦过程。新的 Focusmaster 软件界面允许通过 PC 或笔记本电脑完成整个过程。

Tele Vue 以生产“比您想象的还要好”的视觉仪器而闻名。新款 NP127is 证明他们的目标是通过成像设备实现同样的目标

库存单位：NPI-5054

经过短暂的等待，“重新调整”的 TV127is 现已上市。永不停歇的 Tele Vue 借此机会对其旗舰型号进行了细微但有意义的更改。光学和机械设计都经过了修改，以降低大气散焦敏感度。新的镜头处方在更宽的波长范围内提供比以前更小的光斑尺寸，而新的不锈钢前电池有助于在极端气候下提供更好的热稳定性。采用先进的多层镀膜以最大限度地提高对比度和透射率。它仍然是业内最快的，但考虑到它的 f/5.2 速度和平场，根本没有竞争对手。

PlaneWave 20 英寸 CDK（校正 Dall-Kirkham）光学设计是一种创新解决方案，以实惠的价格提供无与伦比的天文成像质量。CDK 望远镜设计使用大尺寸 CCD 相机提供出色的成像效果，同时仍保持出色的视觉使用效果。CDK 设计的离轴性能远远超过大多数商用望远镜设计，包括 Ritchey-Chrétien 设计。这种不折不扣的设计独特之处在于使光学对准变得容易，准直变得非常简单。这确保了用户从望远镜中获得最佳性能。CDK 设计的图像平面的最终结果是没有离轴彗差、没有离轴散光、完全平坦的视场（没有离轴散焦）。CDK 设计将为您提供从视场中心到角落的精确恒星。有关我们的光学设计的更多信息

PlaneWave Instruments CDK20 是一款 20 英寸（0.51 米）f/6.8 校正 Dall-Kirkham 天文望远镜。CDK20 采用双碳纤维桁架设计，配有 3 个冷却风扇，从望远镜后部排出空气。CDK20 覆盖 52 毫米视野，无任何场曲、离轴彗形像差或像散。该仪器重量为 140 磅（64 千克），标配背板固定环，可随时安装您选择的调焦器。

使用 Celestron 的 Rowe-Ackermann Schmidt 天文照相仪 (RASA 11) V2，捕捉令人印象深刻的深空天文图像比以往任何时候都更容易，它是当今顶级 DSLR 或天文 CCD 相机的完美伴侣。与传统的 f/10 天文成像相比，这种快速、宽视场 f/2.2 系统允许更短的曝光时间，而不会牺牲分辨率。由于可以缩短亚曝光时间，您的赤道仪不需要长时间准确跟踪。短焦距也减少了赤道跟踪要求。在许多情况下，不需要自动导航。

RASA 11 V2 以 Celestron 施密特相机为基础，该相机允许天文摄影师在 20 世纪 70 年代在胶片上拍摄出曝光时间更短的图像。

如今，由于 CCD 传感器尺寸与胶片一样大或更大，RASA 11 V2 可提供 43.3 毫米优化成像圈，以在最大的成像芯片上捕捉精确的星点。对角线宽度高达 52 毫米的巨型传感器而言，光学性能仍然非常出色。

将这个大像圈与仅 620 毫米的焦距相结合，您将拥有一种适合广角成像的仪器，可以创建夜空的巨大马赛克、进行测量，甚至搜寻彗星。

光学性能
RASA 11 V2 的光学元件采用 4 元件稀土玻璃，可消除伪色和彗形像差和场曲等像差。对于这个价格范围内的天文照相仪而言，整个像圈的光学质量和光斑大小是前所未有的，甚至比更昂贵的仪器还要好。该设计还可最大程度地减少晕影。

高级功能
RASA 11 V2 采用超稳定对焦系统 (USFS)。该系统的核心是精密线性滚珠轴承。该轴承用于最大限度地减少焦点偏移（主镜在对焦过程中不必要的横向运动，导致图像偏移）和镜面翻转（望远镜指向天空中不同位置时主镜的移动）。USFS 还与可选的 Celestron 对焦电机 (#94155-A) 兼容。集成的 12V DC MagLev 风扇可缩短冷却时间并通过防尘光学管提供最佳气流。

RASA 11 V2 被设计为一个完整的天文成像系统，其每个组件都针对 DSLR 和天文 CCD 相机的最佳性能进行了优化。系统的每个组件都经过仔细考虑，包括随附的全多镀膜光学窗口或可选成像滤镜中使用的玻璃厚度，以实现无缝协作。光学管顶部的燕尾 CGE 杆提供了连接，可使用导星镜等可选配件。

CDK24’s Key Features

Large Aperture and Moderate Focal Ratio

The CDK24 features a substantial 610 mm aperture and a moderate f/6.5 focal ratio. This setup enhances its capability to capture deep-sky objects with remarkable detail, providing excellent light-gathering efficiency and a broad field of view for research and imaging.

Advanced Optical Design

Equipped with a state-of-the-art Corrected Dall-Kirkham optical system, the CDK24 offers exceptional image clarity. Its design eliminates off-axis coma and astigmatism and delivers a perfectly flat field, ensuring images are sharp and detailed across the entire field of view with minimal post-processing adjustments.

Robust Mechanical Structure

Constructed with a carbon fiber optical tube, the CDK24 is lightweight and durable. Its thermal expansion coefficient ensures minimal focus shift as temperatures change, making it ideal for prolonged observing sessions under varying environmental conditions.

High-Performance Mirrors and Coatings

Utilizing fused silica mirrors, the CDK24 maintains precise optical alignment and surface accuracy, even with temperature fluctuations. Its high-quality coatings enhance light transmission and reduce stray light, optimizing performance for specialized observational tasks.

Thermal Management

The CDK24 is equipped with cooling fans and a Delta-T ready system to achieve thermal equilibrium swiftly. These features help to minimize air turbulence within the tube, thus reducing image distortion and maintaining consistent imaging quality.

Integrated Dew Control

The telescope incorporates advanced dew prevention technology with heater pads controlled by PlaneWave’s software. This ensures that optical surfaces remain clear of condensation during humid conditions, thus maintaining clear and consistent imaging performance.

Application-Specific Benefits

Astrophotography

With its large image circle and exquisite field flatness, the CDK24 allows astrophotographers to capture expansive and breathtaking views of the cosmos with incredible detail and clarity.

Astronomy Research

The precise and stable imaging capabilities of the CDK24 make it an invaluable tool for academic institutions and observatories engaged in complex astronomical research, including deep-sky surveys and detailed photometric studies.

Visual Observations

The CDK24 excels in visual observation, offering bright and crisp views ideal for star parties and serious visual astronomy. The telescope's large aperture and superior optical quality provide stunning views of planetary, lunar, and deep-sky objects, making every viewing session a remarkable experience.

Space Situational Awareness (SSA) and Space Domain Awareness (SDA)

The CDK24 also lend itself to applications in Space Situational Awareness and Space Domain Awareness. Its capability to provide detailed observations can be essential for tracking and monitoring satellites and other space debris, contributing valuable data for space traffic management and safety initiatives.
