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”细节。

Origin 星云滤镜如何工作？发射星云主要发射离散波长的光 — Hα 为 656nm、Hβ 为 486nm、OIII 为 496/501nm。通过策略性地仅传输这些波长的光并阻挡其余光谱，滤镜可显著降低光污染的影响。“坏”光被阻挡，而与发射星云相关的“好”光则穿过 Origin 的传感器。

您会立即注意到图像中的对比度大大提高，尤其是在光污染严重的后院！由于临界波长的透射率很高，星云不会变暗，只有背景会变黑。您还会注意到来自较暗天空的星云图像的对比度有所改善，因为滤光片可以很好地阻挡自然的天空辉光。

星云狩猎

星云滤镜非常适合拍摄发射星云，例如北美洲星云 (NGC 7000)、礁湖星云 (M8)、猎户座星云 (M42)、船底座星云 (NGC 3372) 等数十种。成像滤镜在关键的 Hα-Hβ-OIII 波长中提供最大光传输，为此类发射星云产生高对比度。

星云滤镜的透射光谱在关键波长（486nm、496nm/501nm、656nm）下为 85% 或更高，在其他地方的透射率低于 0.5%。作为窄带滤镜，它会阻挡大部分可见光谱，只让这些特定波长通过。因此，在观察或成像宽带发射物体（如星系和星团）时，不应使用此滤镜。对于这些物体，您可以通过移除星云滤镜并重新安装 Origin 的透明光学窗口来获得最佳效果。

市场上其他类似的成像滤光片在关键的 Hα-Hβ-OIII 波长处具有更窄的带通。不幸的是，对于 Origin 的 6” RASA 等 f/2.2 光学系统，这些滤光片会阻挡大部分入射的 Hα-Hβ-OIII 光。这是因为 RASA 以更陡的角度将光带入滤光片，从而导致光谱偏移。如果您使用的滤光片不是专门设计用于 f/2.2，那么来自星云的部分光线将被阻挡，从而导致图像变暗。Origin 的星云滤光片是专门为 f/2.2 设计的，因此来自星云的“好”光不会被滤光片无意阻挡。

主体和存储

该滤镜采用机加工的黑色阳极氧化铝盒，带有滚花边缘，便于安装时抓握。我们添加了防反射涂层，有助于抑制玻璃上的反射。滤镜可直接放入 Celestron Origin 前镜头盒中的滤镜抽屉中，光学窗口就位于此处。只需取下透明窗口并将其替换为滤镜即可。安装滤镜后，Origin 可在整个系统中保持其光学性能。无需其他适配器。

每个滤镜都配有一个泡沫衬里的塑料储物盒，可以在不使用时安全存放滤镜或 Celestron Origin 附带的光学窗玻璃。

Celestron 会单独测试每个 Nebula Filter for Origin，以验证其性能。除了您的滤镜，您还将收到一张光谱传输图（如上图所示），其中显示了您的滤镜测试结果，并验证其在整个光谱范围内的表现是否符合预期。

规格：

为了获得最佳的天文图像，重要的是要获得相机相对于与其配合使用的望远镜的适当后焦距。如果相机使用的后焦距不准确，全画幅成像传感器角落的性能将受到影响——星星会显得细长，而不是像针尖一样。
示例：RASA 8 搭配 ZWO ASI 183 MC PRO 相机

• 带有 M42 相机适配器的 RASA 8 所需的后焦距：25 毫米
• ZWO ASI 183 MC PRO 相机消耗的后焦距：17.5mm
• 为了实现相等的后焦距，需要一个 7.5mm M42 垫圈

Celestron 的 M42 垫圈套件包括三个不同长度的垫圈，以便与我们流行的 Celestron 光学管和 T 型螺纹相机适配器实现适当的后焦距离。

如何使用
根据您的天文摄影方法（DSLR 或 CCD/CMOS），有两种使用 M42 垫圈的方法。如果您使用的是 DSLR，请将所需的 M42 垫圈放在 T 形环和光学筒的 T 形适配器之间。如果您使用的是 CCD 或 CMOS 相机，请将所需的 M42 垫圈放在相机和光学筒的 T 形适配器之间。

以下是一份快速指南，可帮助您确定我们的 EdgeHD、施密特-卡塞格林和 RASA 8 光学管应使用哪种垫圈：

此 T 型环仅适用于 EOS M 卡口无反光镜相机。如果不添加佳能适配器将这些相机转换为 M 卡口，它将无法与其他佳能相机机身（如 EOS RF 卡口或 EOS EF 卡口型号相机）配合使用。

T 型环是您通过望远镜或观景镜拍照时需要的第一批配件之一。如果您有佳能 EOS 无反光镜相机机身，Celestron EOS M-Mount T 型环就是您的不二之选。

如何使用
要使用此 T 形环，请将 M 型安装 T 形环放在佳能无反光镜相机上。就像更换镜头一样，将 T 形环对准相机的镜头座。将其推入并旋转，直到听到咔嗒声。T 形环有一个坚固的卡口法兰，可以锁定以确保牢固安装。将 T 形环安装到相机上后，即可连接望远镜。T 形环的望远镜侧有螺纹，可以接受各种相机适配器，包括 Celestron T 适配器。您选择的适配器取决于您想要进行的摄影类型。

Bintel UHC Narrowband Filter – 1.25"

The Bintel UHC Narrowband Filter is designed to dramatically improve contrast when visually observing emission nebulae, especially from light-polluted suburban and city skies. By selectively passing key nebular emission lines while blocking common artificial light sources, it helps faint objects stand out more clearly against a darker background sky.

Unlike broadband filters, the UHC’s narrower passband delivers stronger contrast on classic nebulae such as The Orion Nebula, The Carina Nebula, The Lagoon Nebula and so many more. Even under urban lighting, brighter nebulae become easier to detect, while dark-sky observers will appreciate the added structure and subtle detail revealed.

Advanced multilayer dielectric coatings provide excellent transmission (over 97% across the passband) while fully blocking major light pollution lines. This high efficiency makes the filter particularly effective with small to medium aperture telescopes. Ion beam–hardened coatings ensure long-term durability and scratch resistance.

Key Features

• Ultra High Contrast (UHC) narrowband design for visual observing

• Strong enhancement of emission nebulae contrast

• High transmission at H-beta (486.1nm) and OIII (495.9nm & 500.7nm)

• Over 97% transmission across the passband

• Effectively blocks common light pollution wavelengths

• Durable multilayer dielectric, ion beam–hardened coatings

• Standard 1.25" filter thread fits most eyepieces

Specifications

• Type: UHC light pollution suppression filter

• Size: 1.25" (standard thread)

• Material: Optical glass with aluminium cell

• Application: Screws directly into the barrel of 1.25" eyepieces

An essential visual filter for anyone who enjoys observing nebulae, the Bintel UHC Narrowband Filter delivers noticeably darker skies, brighter nebulae, and more rewarding views, especially where light pollution would otherwise limit what you can see.

The Celestron StarPointer Finderscope is the way to go if you want the easiest way possible to locate an object and center it in your eyepiece.

A red dot finder, unlike an optical finder, has 1x magnification, displays a super wide field of view, and keeps the sky right side up and left-to-right correct, matching what you see with your unaided eyes. An LED creates a red dot, superimposed on a viewing screen, so you simply point the StarPointer to the area or object you wish to observe, look through your eyepiece, and if properly aligned, the area in and around place you pointed the red dot will be centered in the field of view.

If you like the idea of having some magnification, try installing both a red dot and optical finder on your telescope. Schmidt-Cassegrain and EdgeHD telescopes have multiple mounting bracket holes so you can get the best of both worlds. Just make sure to align both of them correctly, and you’ll get the best use out of each of your finders.

How to Align the StarPointer Finderscope

The first time you use your finder, you need to align it. This one-time setup procedure should be done during the day. Take the telescope outside and find an easily recognizable object, such as a streetlight, car license plate, or tall tree. The object should be as far away as possible, but at least a quarter mile away. Move the telescope left and right or up and down so that it is roughly pointing at the object. Look through the telescope using your low power eyepiece and move the telescope until the object you chose lies in the center of the view. Once the object is centered in your eyepiece, turn on the red dot. With your head positioned about a foot behind the finder, look through the round lens of the finder and locate the red dot. Without moving the telescope, use the two adjustment knobs located on the side and underneath the finder. One controls the left-right motion of the dot. The other controls the up-down motion of the dot. Adjust both of these until the red dot appears over the same object you are observing in the eyepiece.

Your finder is now aligned and should not require realignment unless it is bumped or dropped. You can even take the finder off the telescope and reattach it while preserving alignment.

The Lunt Solar Systems Pressure Tuner Controller, or PC-USB, is a microprocessor controlled, remote operable* , pressure control system that can be retrofitted to any Lunt PT product without return to the Lunt facility. A simple 1/8″ airline connects the PC-USB to the Solar Telescope and can be installed at any length.

The PC-USB is a simple 2 button system. One button for increasing and one button for decreasing the PT pressure. Digital feedback and indicator lights are provided.

The PC-USB can run continuously on internal battery power for more than 12 hours. It has external power input (12-15 VDC) (120/240 VAC to 12 V adapter) that can power the unit and charge the internal batteries simultaneously.

All existing PT systems can be retrofitted via an adapter to the pressure tuner knob. Or, future PT units can be specified with a quick disconnect at the PT input, removing the PT knob from the telescope altogether.

Upon power up the PC-USB will go thru a systems vent and ambient pressure set mode. It can be factory or user programmed to center wavelength setpoint. Due to the sealed nature of the system, the center wavelength setpoint will remain constant at any altitude at a given set pressure point.

The Pressure Tuner Controller is accurate to 0.3 PSI, providing very precise control of the pressure setpoint. It will auto-compensate for fluctuations in internal pressure changes due to significant changes in temperature. Because the PC-USB can provide closed-loop feedback of internal etalon pressure, users can correlate change in pressure to doppler shifted events.

The Sky-Watcher 2-Inch NOMAD 4 4x Tele-Centric Focal Extender is a high-quality optical accessory with a variety of uses and connecting options for visual and imaging use.

VISUAL USE: Used as a Barlow Lens with an eyepiece for visual use, NOMAD 4 effectively multiplies the magnification of any eyepiece by five times, allowing for detailed observations of celestial objects such as the Moon and planetary surfaces. Constructed with premium high-index glass elements and multi coatings, it ensures minimal light loss and maximum clarity. Features a self-centering brass compression ring which avoids marring to eyepieces and a captive eyepiece retaining screw.

IMAGING USES: The premium 4-lens design provides images without colour difference as well as providing excellent field collimation. NOMAD 4 is ideal for taking spectacular high resolution photos of planetary surfaces or the surface of the Moon without compromising the quality of the telescope. So in other words it will maintain the apochromatic performance of an ED Apo telescope!! A CCD camera can be mounted directly using the supplied CCD adaptor. A DSLR camera can be mounted with the supplied DSLR adapter (camera M48x0.75 ring required).

The NOMAD 4 will be a very useful addition to the toolkit of many an astronomer !

  Eliminate the need for your full-height tripod and enjoy grab-and-go convenience when you add the Tabletop Tripod to your NexStar Evolution, NexStar SE, or Celestron Origin telescope. This compact and sturdy accessory is half the size and weight of a standard tripod, making it perfect for travel. The low-profile legs and wide footprint offer added stability, while the convenient tabletop design makes it easier for some observers (especially children) to access the eyepiece.

  Setup is quick and easy compared to a full-height tripod. Simply place the Tabletop Tripod on a camp table, bench, tailgate, or any other flat surface. With a footprint of just 17.5” x 16”, you can use it just about anywhere. Then, open and level the tripod legs, attach the mount and telescope, and you’re ready to go.

  The Tabletop Tripod has adjustable knobs on each leg and a bubble leveler on the mount plate to ensure your setup is level before adding the telescope. Just like the NexStar SE, NexStar Evolution, and Celestron Origin’s standard tripod, the Tabletop Tripod has three captured screws on the underside of the mount plate so you can securely lock your mount and telescope in place.

  When not in use, the Tabletop Tripod’s legs fold inward and stow neatly under the mount plate for easy storage and transport.
