Farpoint Bahtinov Mask - Celestron 9.25 Classic
About Bahtinov Masks
Pavel Bahtinov, a Russian amateur telescope maker and astronomer, created this simple, very intuitive method and the device has universally been named after him: The Bahtinov Mask.
Attach a camera to the telescope, center a fairly bright star and achieve rough focus. Then place the mask over the front aperture of your telescope by “hanging” it on the plastic screws from the front dew shield (Custom fit masks for specific telescopes are also available). Take a short exposure. The image of the star will show diffraction spikes. The “center” spike will most likely be shifted to one side or the other. This is showing the defocus.
Adjust the focus of the telescope and re-expose the star, once again showing the diffraction spike pattern. Iterate the process until the central diffraction spike is centered against the star and the other spikes. When a symmetrical pattern is achieved, the best possible focus has been obtained. Simply remove the mask, center the target object and take amazing, sharp images!
Farpoint manufactures this "lifesaving" astrophotography tool out of virtually indestructible ABS plastic, which comes in three major types and in a range of sizes. In addition to Bahtinov masks for telescopes, Farpoint also makes Bahtinov masks for DSLR camera lenses.

Farpoint Bahtinov Mask RASA 8" 专为 Celestron 8 英寸 RASA 望远镜设计,是一种轻松聚焦望远镜的巧妙方法。俄罗斯业余望远镜制造商和天文学家 Pavel Bahtinov 创造了这种简单、非常直观的方法,该设备普遍以他的名字命名:Bahtinov Mask。
Farpoint Bahtinov 面罩 RASA 8 英寸
Farpoint Bahtinov Mask RASA 8" 是一种巧妙的望远镜聚焦方法。俄罗斯业余望远镜制造商和天文学家 Pavel Bahtinov 创造了这种简单、非常直观的方法,该设备普遍以他的名字命名:Bahtinov Mask。
将相机安装到望远镜上,将一颗相当明亮的星星置于中心并粗略对焦。然后将遮光罩“悬挂”在前防露罩的塑料螺丝上,置于望远镜的前孔上。进行短暂曝光。星星的图像将显示衍射尖峰。“中心”设置很可能会向一侧或另一侧移动。这显示了失焦。
调整望远镜的焦距并重新曝光恒星,再次显示衍射尖峰图案。重复该过程,直到中心衍射尖峰与恒星和其他尖峰居中。当实现对称图案时,即可达到最佳焦距。只需取下遮罩,将目标物体置于中心,即可拍摄出令人惊叹的清晰图像!
Farpoint 用几乎坚不可摧的 ABS 塑料制造了这款“救命”的天文摄影工具,这种塑料有两种主要类型和各种尺寸。除了望远镜的 Bahtinov 遮光罩外,Farpoint 还制造数码单反相机镜头的 Bahtinov 遮光罩。
Farpoint Bahtinov 遮光罩是天文摄影师可用的最佳手动调焦望远镜工具之一。2005 年,俄罗斯业余望远镜制造者和天文学家 Pavel Bahtinov 详细介绍了一种通过添加与望远镜直径相匹配的遮光罩轻松调焦 DSLR、CMOS 或 CCD 相机进行天文摄影的方法。
与标准电动调焦器相比,巴赫蒂诺夫面罩是一种更便宜的聚焦夜空物体的方法。
使用正确的遮罩和设置,您可以在不到 90 秒的时间内轻松清晰地聚焦在一颗星星上。
工作原理
遮罩中的狭缝是辅助对焦装置,当星星聚焦时,它将在屏幕显示上显示为一个“X”,中间有一条线(见上文)。
这些面罩在瞄准镜末端或防露罩末端的作用同样好,而且面罩本身不需要完美地集中在瞄准镜的中心,这是由于狭缝本身的角度所致。
选择一颗明亮的星星,这将是您的引导物体。将 Bahtinov 聚焦罩放在望远镜的镜头上,并使用提供的橡胶片将其固定到位。
遮罩设计中的狭缝会在恒星上形成一组衍射尖峰,这将有助于我们精确对焦。它将在您的 DSLR 显示屏或计算机上显示为一个“X”,中间有一条线(对焦时)。

在防结露方面,要更聪明地工作,而不是更努力地工作。智能除露加热器和电源控制器 4X 可优化最多四个除露加热器的功耗,从而延长电池寿命。控制器实时收集和分析信息,以刚好加热光学元件以防止结露。
智能除湿加热器和控制器配有四个端口,可同时控制四个除湿加热器。您可以使用一个端口加热光学管,而其他端口加热第二个光学管、导向镜、目镜或其他配件。控制器也是望远镜的完整电源管理解决方案。它提供四个 12V DC 输出端口,可为各种 12V DC 设备供电,例如您的支架、调焦电机和相机。其中一个端口具有可变电压,您可以将其从 3V 调整到 12V。此外,控制器还具有三个供电 USB 端口。
智能除湿器和控制器可与 Celestron 的除湿器加热环无缝配合使用,后者内置热敏电阻,可提供校正镜头的温度读数。第三方除湿器加热带或带子也兼容;您只需添加 Celestron 的智能除湿器和控制器热敏电阻(单独出售)。
智能控制
控制器的核心是一个强大的微处理器,它可以从传感器收集信息、计算数据并自动调整除露加热器。控制器使用其集成的环境传感器监测环境温度和湿度,并使用热敏电阻监测加热器的温度。
您可以将 Smart DewHeater 和 Power Controller 4X 作为独立附件运行。或者,如果您想查看控制器中的数据并进行手动调整,您可以将其连接到 Celestron 望远镜的手动控制器或 PC。该控制器可与运行最新固件或 Celestron CPWI 望远镜控制软件的 NexStar+ 或 StarSense 手动控制器配合使用,这些软件随每个 Celestron 支架提供。
力量
Smart DewHeater 和 Power Controller 4X 采用 12V DC 电池(如我们的PowerTank Lithium Pro或PowerTank 17 )运行,最大可处理 240W 的功率(12V DC 时最大电流为 20A)。
控制器还具有四个 12V DC 输出端口,因此您可以从单一电源为整个设备供电。您可以使用其他端口为支架、对焦马达和相机等设备供电。其中一个电源端口提供可变电压,可在 3V 至 12V 之间调节。此端口非常适合使用低于 12V DC 的配件,例如 DSLR 相机。
连接后,您可以使用手动控制器或 CPWI 软件单独控制每个设备的电源。无需从控制器上拔下连接的设备即可关闭它们。如果电流消耗过高,所有设备都受到可复位电子保险丝的保护。
注意:如果您在重露条件下使用多个除露加热器并为外部 12V DC 设备供电,则一个 PowerTank Lithium Pro 或 PowerTank 17Ah 将没有足够的容量来整夜运行您的设备;您将需要更大容量的电池或多个电池。
USB 3.2 集线器
集成的 USB 3.2 集线器仅用一根电缆即可将三个 USB 设备连接到您的计算机,大大简化了电缆管理。有三个 USB A 型端口,每个端口都带电。就像 12V DC 端口一样,您可以使用 CPWI 或 Celestron 手动控制器打开或关闭每个 USB 端口的电源。
独特的工业设计
Smart DewHeater 和电源控制器 4X 具有重型金属外壳。内部的冷却风扇可保护控制器的电子设备。
桥接器– 在控制器的顶部,您会发现桥接器,它是设备状态 LED 和环境传感器的所在地。桥接器还有助于电缆管理。我们将温度和湿度传感器放置在这里,远离控制箱和其他可能产生热量的组件。与竞争对手的产品不同,我们的传感器不需要额外的电缆即可获得准确的读数。
桥上的 LED 灯指示设备的当前状态。如果控制器消耗的电流超过电源所能提供的电流,或者电池需要充电,LED 灯会发出警告。如果天色昏暗,您可以调暗灯光。
安装– Celestron Smart DewHeater 和 Power Controller 4X 可通过集成燕尾夹安装在 CGE 或 CG-5 燕尾上。如果您希望将控制器安装在三脚架腿上,请使用随附的带子。
Smart DewHeater 和电源控制器 4X 配备有:
- 智能除湿器和电源控制器 4X
- 三脚架腿带
- 控制器电源线
- 外部 12V DC 设备电源线
- 用于连接 Celestron 支架的 AUX 电缆
- 热敏电阻延长线,用于连接至 Celestron 的除露加热器环
增强您的设置
我们强烈建议将此控制器与 Celestron 除露加热环搭配使用。它们可以无缝贴合您的施密特校正镜头,并可全年改善您的观察或成像效果。
为了达到最高程度的防露效果,我们还建议在您的设备中添加防露罩。虽然不是必需的,但防露罩会减少控制器需要向防露加热器环提供的电量,以保持光学器件清晰。

saxon Plossl eyepieces can be used on all types of telescopes - refractors, reflector, and catadioptrics such as Celestron SCT telescopes.
Featuring a 4-element design, this Plossl eyepiece ensures maximum light transition, minimises spherical aberration, distortion, astigmatism, and off-axis colour. The edge-to-edge blackened optics provide excellent contrast across the 52° apparent field of view.
This 32mm size will offer a lower magnification than the 25mm size provided as standard with most telescopes. It's a handy way to obtain a wider field of view for large deep-sky objects including many nebulae and star clusters.
The oversized optical elements provide long eye relief while stray light is eliminated by the fold back rubber eyecups.

A guide to the special birds found across Australia’s vastly varied landscapes.
From the eastern rainforests to the central deserts, Australia is home to some 900 species of birds. Finding Australian Birds covers over 400 birdwatching sites conveniently grouped into the best birding areas, from one end of the country to the other. This includes areas such as Kakadu in the Top End and Uluru in the Red Centre of the Northern Territory, the Great Barrier Reef in Queensland, an amazing diversity of forests along the eastern Australian seaboard, including some of the world’s tallest forests in Tasmania, the iconic Strzelecki and Birdsville Tracks in South Australia, and the mallee woodlands and remote Kimberley region in Western Australia.
Chapters are arranged by state or territory and begin with an overview. Birdwatching sites are then grouped by region to provide specific details on target species, access and useful information such as accommodation and facilities. This second edition includes over 30 new birdwatching sites and updated information on site access. The book also provides a comprehensive ‘Bird Finding Guide’, listing all of Australia’s birds with details on their abundance and where exactly to see them.
Finding Australian Birds will be valuable to both Australian birdwatchers and international visitors. It will assist novices, birders of intermediate skill and keen ‘twitchers’ to find any Australian species.
Praise for the first edition:
"Twitchers will find this a most agreeable companion but all bird-loving travellers should pop a copy in their backpack, along with good binoculars."
Susan Kurosawa, Weekend Australian, June 2014
"The amount of detailed information within its pages will be enough to make even the best-travelled birders eager to get out and check a few more sites"
Chris Watson, Australian Birdlife, June 2014
"This excellent birdwatching site guide by Tim Dolby and Rohan Clarke will save you time if you are planning an Australian birdwatching trip, and is sure to help you find more of your target species... you wouldn’t want to plan an Australian birding trip without consulting this one."
Michael Szabo, Birds New Zealand (16), December 2017
Includes:
- Fully updated second edition, featuring new sites and current site access details.
- Up-to-date information on 400+ good birding locations in Australia, written by experts with first-hand knowledge of the sites.
- An easy-to-use travel companion for local and international birdwatchers on Australia’s best natural sites.

Your telescope's focuser is used to compensate for your near- or far-sightedness; DIOPTRX™ compensates for your astigmatism. These units attach and lock onto the tops of over 20 long eye-relief Tele Vue eyepieces to achieve the sharpest full-field viewing possible. DIOPTRX™ models are available in ½ to 3½ diopter and are rotatable for tuning to the best orientation. A series of engraved letters on the barrel helps to monitor orientation. Simply choose the DIOPTRX™ model that matches your eyeglass prescription for astigmatism. All lenses are multi-coated glass in anodized aluminum housings with rubber eyeguards.
1. You're more likely to see a sharper, higher contrast image, because:
A. The Dioptrx is always completely aligned to the eyepiece optics, eliminating aberrations from a decentered mismatch of eyeglass power and astigmatic axis.
B. Dioptrx can be rotated to exactly compensate for the astigmatic axis angle in real time, since both head angle and age can vary your eyesight astigmatic angle.
C. Dioptrx likely has better multi-coatings than eyeglasses, and certainly is better in transmission and reflection reduction than uncoated eyeglass.
D. Dioptrx is more likely to be cleaner than eyeglasses, which may have scratches and smudges from constant use and wear and tear.
E. Dioptrx allows seeing your normal maximum contrast that eyeglasses can diminish (remove your eyeglasses and see how contrast improves in normal vision).
2. You're more likely to see the full field in 100° Ethos eyepieces because your eyeglasses are more limiting in "effective eye-relief".
How To Choose
Simply choose DIOPTRX™ to match the cylinder (astigmatism) value of your preferred viewing eye. In the example above, you would choose 0.5 diopter model for your right eye and 1.5 diopter model for your left eye.
- Ignore spherical and axis values.
- Ignore all ± signs

Astronomik now offers you a range of three different UV+IR blockers as Luminance filters. The different spectral window of each new Luminance filters is designed to tune your setup to get the sharpest image from any optical design and any camera.
The Luminance channel is probably the most important for a great final image! You want as much signal as possible so the filter should have the highest transmission possible with a wide spectral bandpass. This combination provides the greatest sensitivity and gives you the highest photon counts on your pixels. While the high transmission level is a great aspect of the new Astronomik Luminance filters, not all optical instruments or additional optical elements like correctors, field-flatteners or reducers, have perfect colour correction so it can be the width of the spectral band pass of the Luminance filter that can cause problems. A band pass that is too wide will allow the transmission of incompletely focused light (Chromatic aberration), making stars appear soft or bloated. In such cases image processing can become difficult, so having a slightly narrowed spectral window in your Luminance filter can reduce or eliminate this damaging effect.
To give you all the tools to gather the best data possible we have expanded our line of Luminance filters: Now you can select a Luminance filter perfectly matched to the kind of telescope you use, to get the highest signal and sharpest image for the Luminance channel!
Depending on the color correction of your scope you may use a wider spectral window for the Luminance data. The L1 filter has the widest spectral window, the L2 is about the same as our current L-Filter and the L3 is much narrower.
If you use an optical system that is completely free of any chromatic aberration you should get an L1 filter for your setup. For general use the L2 filter is well suited to most optical systems with a corrector, flattener or reducer in the optical train while the L3 filter is designed for users of refractors with a less-than-perfect color correction and in combination with the new Deep-Sky RGB filters, the L3 filter will minimise the problem of bluish halos around stars.
The transmission curve characteristics and coatings on the new Luminance filters have been designed and engineered in such a way that no halos or reflections will be visible. Even with bright stars in the field of view you will be able to reveal the faintest structures in nebulas or galaxies.
Like all Astronomik Filters, the new Luminance filters are made using an extremely durable and scratch resistant coating, deposited on the finest polished optical substrate, which is free of any striae or internal strains. All substrates are made to exactly the same thickness, so all of our filters are parfocal.
Additional note for observers working under light polluted skies:
If your observing site suffers from light pollution you should try to use our CLS-CCD as a replacement for the Luminance filter. The transmission curve of the CLS-CCD will give you approximately the same amount of energy in all three colour channels while blocking nearly all unwanted artifical light pollution. Customers who replaced the Lx filter with the CLS-CCD are amazed by the increased quality of their data. This small change gives you the opportunity to take much deeper images from your current observing site.

The UHC (Ultra High Contrast) broadband filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow). Together with the highly transparent in main nebula emission lines at OIII(496nm and 500nm), H-beta (486nm), NII(654nm and 658nm), H-alpha(656nm) as well as SII(672nm), the filter is suitable for enhancing the contrast and details for both visual and photograghic purpose at sub-rural area with heavy light pollution.
Main Use and Performance
Suitable for color CCD cameras and unmodified DSLRs.
UHC with narrower passband provides higher contrast than CLS. Thus it is more suitable for urban environment where you suffer from severe light pollution.
UHC has a substantial red passband and offer superb views for objects like the Orion Nebula (M42).
Light pollution filter do not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula.
WARNING: The filters of Optolong are not designed for sun observation. DO NOT LOOK AT THE SUN WITH OPTOLONG FILTER. You would be BLIND if you fail to observe the warning.
