The night sky, at f/2.2.
The smallest Rowe-Ackermann Schmidt Astrograph ever built. Ultra-fast prime-focus optics, sub-arcsecond resolution and 3.8 kg of grab-and-go portability for serious deep-sky astrophotography, anywhere.
Professional optics. In a body you can carry with one hand.
Patented Rowe-Ackermann Schmidt architecture.
The RASA places the camera at prime focus, the same position used by professional wide-field survey telescopes. No secondary mirror, no Barlow, no lost light. More photons reach your sensor, in less time.
Since RASA technology debuted in 2014, defence contractors, professional researchers and governments have relied on it for space surveillance and satellite tracking. The RASA 6 delivers that same proven design in a portable package.
- Schmidt corrector plate and primary mirror minimise optical aberrations across the field
- Three-element rare-earth glass lens group ensures sharp, flat focus edge-to-edge
- Spot size under 1.5 μm RMS across the full image circle
NGC 6888. The Crescent Nebula.
Captured with the RASA 6 and an astronomical CMOS camera. Short sub-exposures stack into stunning images in a fraction of the time needed by slower instruments.
Four reasons it’s unlike anything else in its class.
Speed, resolution, portability and field of view, all engineered into one compact prime-focus astrograph.
Lightning-fast astrophotography at f/2.2.
The RASA 6’s blazing focal ratio dramatically shortens sub-exposure times. Faint deep-sky objects that would take hours with a typical refractor can be captured in a fraction of that time. Paired with live-stacking software, bright detailed images appear on your screen in just minutes. In many conditions you can image without an autoguider, simplifying your entire setup.
Sub-arcsecond potential.
Despite its compact size the 152 mm aperture delivers a Dawes resolution of 0.76 arc seconds. Pair it with a high-resolution CMOS camera in steady seeing and you will resolve fine structure in galaxies, nebulae and star clusters that smaller instruments cannot touch. The flat field means stars stay sharp from the centre all the way to the corner of the sensor.
Grab-and-go, genuinely.
At 3.8 kg the RASA 6 is light enough to carry with one hand and fits in a bag alongside your mount. The CG-5 dovetail means it drops straight onto most mid-range tracking mounts without adapters. Chase dark skies without compromising on optical performance. This is the astrograph you will actually take with you.
Wide field without sacrifice.
The RASA 6 is designed for sensors up to 22 mm diagonal, delivering a useable field of 3.76°. Wide enough to frame the Orion Nebula, the Pleiades and large emission nebulae in a single shot. Off-axis illumination of 91% at 8 mm means the field stays bright from edge to edge, reducing processing time on flats and vignette correction.
StarBright XLT. Maximum light throughput.
Every refractive and reflective surface is treated with Celestron’s proprietary StarBright XLT multi-layer coating. The result is exceptional light transmission and superior field illumination across the full wavelength range from 400 to 700 nm.
The RASA design outperforms a Schmidt-Cassegrain in Fastar-style configuration for field illumination. Less vignette, less processing, more imaging.
M42. The Orion Nebula.
IMX183C colour CMOS camera. 60 × 2 min exposures plus 20 × 15 sec exposures for the bright core. The wide field and fast optics of the RASA 6 capture the full extent of the nebula in a single frame.
Everything the modern astroimager needs, integrated.
A filter drawer, a cooling fan, a camera adapter and a CG-5 dovetail. Ready to image, straight out of the box.
1.25″ and 2″ filters. Without slowing you down.
The built-in filter drawer accepts both 1.25″ and 2″ filters. A removable 2″ clear optical window ships as standard. Unlike many fast astrographs, swapping in a filter adds no extra glass to the optical path, so f/2.2 performance is fully preserved.
Thermal equilibrium, fast.
The integrated 12V DC MagLev fan pulls air through mesh vents to rapidly cool the optical system to ambient temperature. Sharper stars and better images from the moment you start. The fan battery pack is included.
Plug a CMOS camera straight in.
The included M42 T-thread camera adapter attaches most popular astronomical CMOS cameras directly to the RASA 6 without extension tubes. The 42 mm clear aperture comfortably accommodates sensors up to 22 mm diagonal. Back focus with the included adapter is 17.5 mm.
Mount-ready, no adapters.
The CG-5 dovetail bar is compatible with a wide range of tracking mounts straight out of the box. No adapters, no Vixen-to-Losmandy conversions. Ready to image as soon as you saddle up. For maximum performance, add the optional Celestron Focus Motor for electronic focus control.

借助专为 RASA 设计的这款光污染成像滤镜,即使在光污染的天空下,也能充分利用 Celestron Rowe-Ackermann Schmidt Astrograph 11。无论您使用哪种相机,这款滤镜的宽大 68 毫米通光孔径都使其能够轻松容纳当今最大的传感器。这款滤镜采用机加工铝制外壳和 Schott B270 玻璃,取代了 RASA 的透明光学窗口,因此 RASA 的光学性能不会受到影响。
消除光污染,同时保持图像明亮
光污染限制了我们能够看到和拍摄的夜空范围。在光污染区域使用彩色相机拍摄时,天空辉光会降低图像质量。光污染滤镜有助于选择性地阻挡普通路灯和其他环境照明发出的光线。但大多数光污染滤镜会严重影响总光通量,导致图像暗淡,并对色彩平衡产生负面影响,导致图像显得太绿或太蓝。
RASA 的光污染成像滤镜“精准”地去除了不需要的光污染,同时尽可能多地保留有用的光谱。这意味着您仍将保留望远镜在许多波长下捕获的 90% 以上的光线。
与其他光污染抑制滤镜不同,Celestron LP RASA 成像滤镜保持相对中性的色彩平衡,因此您可以呈现星系和其他暗淡深空物体的微妙色彩。多层特殊配方的介电涂层可提供所需的透射率,而防反射涂层可最大限度地减少星晕和内部反射。
还包括一个透明塑料盒,用于在不使用时保护过滤器

The Astronomik 6nm H-alpha filter is an extremely narrow emission-line filter for CCD photography. The filter lets the H-alpha light of emission nebulae pass and blocks nearly the whole remainder of the spectrum where the CCD is sensitive.
The full width at half-maximum (FWHM) of 6nm is optimized for a maximum contrast between the (H-alpha emitting) object and the background. The contrast gain is much higher than with our 12nm emission line filters but you won’t see as much stars in the resulting images.
The design of the transmission curve makes it possible to use the filters with instruments from 1:3.75 to 1:15. Selected filters for faster system are available upon special request.
All transmission curves of the 6nm filter are measured individually. Because of this procedure you can get the optimum filter for your telescope: If you place a direct order please specify the focal ratio of your instrument and we will select the best filter for your setup. So you may get the best filter without paying for an A+ filter.
Main use
The Astronomik H-alpha-CCD (6nm version) increases the contrast between objects, in this case between the H-alpha emission line and the skyglow background in the same way as the 12nm version. The gain in contrast is much higher due to the smaller FWHM. The 6nm H-Alpha filter is the right choice for extremely dim objects, even in the milkyway, and for observations from heavily light-polluted places. The Astronomik 6nm H-alpha-CCD completely suppresses the emission lines of artificial lighting (mercury (Hg) and sodium (Na)) and skyglow. Transmission losses and chromatic distortions, which arise with other filters, only occur with Astronomik filters when extremely bright aperture ratios come into play. Selected filters for faster systems are available upon special request.
Other uses
- Using the Astronomik 6nm H-Alpha together with the 12nm H-Alpha gives you the ability to have a maximum contrast in the HII objects and to keep the stars in the final image.
- The Astronomik 6nm H-Alpha filter may NOT be used for solar observation.
Suitability
- Visual observation (dark skies): Unsuitable
- Visual observation (urban skies): Unsuitable
- Film photography: Unsuitable
- CCD photography: Very good, huge contrast enhancement at H II-emission nebulas
- DSLR photography (original): Good, reduced sensitivity in the H-alpha band
- DSLR photography (astro modified): Very good, huge contrast enhancement at H II-emission nebulas
- DSLR photography (MC modified): Very good, huge contrast enhancement at H II-emission nebulas
- Webcam / Video (Planets): Unsuitable
- Webcam / Video (Deep Sky): Unsuitable
Technical Data
- typ. transmission von über 90% at H-Alpha (656nm)
- Parfocal with other Astronomik filters
- Glass thickness: 1mm
- Completely resistant against high humidity, scratches and aging effects
- Diffraction limited, the filter will not reduce the optical performance of your telescope!
- Astronomik filters are delivered in a high-quality, long lasting, filter box
- Since 2008 we do ship filters with a completely new design. Any kind of halo or strange reflection is a matter of past

The Astronomik SII-CCD filter is a narrow-band-filter for CCD photography.The filter lets the light of the ionized sulfur (SII) pass, and blocks nearly the whole remainder of the visual spectrum as well as IR, in which the CCD is sensitive.
The full width at half maximum (FWHM) of 12nm is optimal suitable for common CCD cameras and allows the use of very fast optics. The range of application extends from 1:2.8 to 1:15. Transmission losses and chromatic distortions, which arise with other filters, only occur with Astronomik filters when extremely bright aperture ratios of 1:2 and more come into play. It should be noted, that the filter has a transmission of up to 99%.
Another advantage of the 12nm filters is the good availability of guiding stars for cameras with a built-in-autoguider (SBIG). If you use a very strong filter like our 6nm filter you often won't find a usable guidestar.
The Astronomik SII CCD filter increases the contrast between objects, in this case between those with SII emission lines and the skyglow background. Also, our Astronomik SII-CCD filter completely suppresses the emission lines of artificial lighting (mercury (Hg) and sodium (Na)) and skyglow.
Main use
The Astronomik SII CCD increases the contrast between objects, in this case between the SII emission line and the skyglow background. Our Astronomik SII CCD completely suppresses the emission lines of artificial lighting (mercury (Hg) and sodium (Na)) and skyglow. Due to the high optical quality of the Astronomik H-alpha-CCD substrate you will see the same needle-sharp stars as you would from your regular telescope.
Other uses
- Using the new H-alpha-CCD and the new SII-CCD filters you can obtain three-color images of emission line objects (gas nebulae) from locations with very strong light pollution. To do so, you would take an image in three different wavelengths, select each one as a color-channel in Photoshop and paste them together as one single color image.
- If you plan to create color images from emission line data, our CLS-CCD filter is a great choice for the Luminance channel.
Suitability
- Visual observation (dark skies): Unsuitable
- Visual observation (urban skies): Unsuitable
- Film photography: It depends, but very long exposure times
- CCD photography: Very good, huge contrast enhancement at S II-emission nebulas
- DSLR photography (original): Unsuitable
- DSLR photography (astro modified): Very good, huge contrast enhancement at S II-emission nebulas
- DSLR photography (MC modified): Very good, huge contrast enhancement at S II-emission nebulas
