This will fit all telescopes with a standard finderscope dovetail shoe. If you want to attach this to a Celestron SCT tube, you can use this BINTEL accessory:

The Celestron C9.25-A is an unusual size with its 9.25” aperture and 2350 mm focal length, but many consider it to be the Goldilocks of optical tubes—not too big, not too small. This rugged aluminum optical tube is only 558mm long and weighs just 9kgs, making it easy to transport and set up. But the views are much more impressive than what you’d expect from such a compact instrument. The tube offers a focal ratio of f/10 with the added versatility of Fastar (see below).

It is equipped with Celestron’s patented StarBright® XLT optical coatings, which visibly increase contrast and light transmission for brighter deep space images and shorter exposure times. With StarBright XLT, you’ll be able to discern subtle details while viewing the Moon and planets as well as faint galaxies and nebulae.

The Celestron C9.25-A can be mounted on a multitude of computerized telescope mounts thanks to its CGEM-style dovetail bar. This iconic optical tube provides the best balance of portability, handling ease, light gathering ability and price ever offered to the amateur astronomer.

Fastar Technology

In 1997, CCDs were making a name for themselves in the astrophotography world, quickly supplanting traditional film photography thanks to their speed and convenience. This was the year that Celestron joined forces with the Santa Barbara Instruments Group (SBIG) to produce Fastar, a revolutionary add-on to Celestron’s hugely popular Schmidt-Cassegrain (SCT) optical system.

With Fastar, the SCT’s secondary mirror can be removed and replaced with a field-flattening lens assembly (sold separately by third party manufacturers) so that a CCD camera can be used in the front of the telescope at the f/2 focus of the instrument’s primary mirror. The potential of the Fastar system is staggering: exposures are 25 times shorter than if the camera was placed at the instrument’s native f/10 focus. Imagers can capture galaxies and nebulae with exposures of just 30 seconds.

StarBright XLT coatings

StarBright XLT is Celestron’s revolutionary optical coating system. It consistently outperforms all other coatings in the commercial telescope market. There are three major components that make up our StarBright XLT high-transmission optical system design:

• Unique enhanced multi-layer mirror coatings made from precise layers of aluminum, SiO2 (quartz), TiO2 (titanium dioxide), and SiO2 (silicon dioxide). Reflectivity is fairly flat across the spectrum, optimizing it for both imaging and visual observing.
• Multi-layer anti-reflective coatings made from precise layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide). Hafnium—a rare element that costs nearly $2,000 per kilogram—gives us a wider band pass than the titanium used in competing coatings.
• High-transmission water white glass is used instead of soda lime glass for the corrector lens. Water white glass transmits about 90.5% of light without anti-reflective coatings; that’s 3.5% better than uncoated soda lime glass. When water white glass is used in conjunction with StarBright XLT’s anti-reflective coatings, the average transmission reaches an astonishing 97.4.

The 3.5mm Nagler Type 6 is a natural progression of 1.4x power steps from 7mm and 5mm Naglers. You don't have to sacrifice field in order to gain sharpness and power. And, you're not limited to slow scopes, or have to squint through tiny eye lenses. These are the lunar and "planetary" eyepieces with field to spare.

Nagler Type 6

TMB PlanetView Planetary Eyepieces:

The TMB PlanetView Planetary Eyepiece series is designed for high-magnification planetary and lunar observing, delivering sharp, high-contrast views with excellent eye comfort. Choosing the right focal length for your telescope typically provides a significant upgrade in magnification and fine detail compared to the stock eyepieces supplied with most telescopes, making planetary features clearer and easier to observe. Featuring a 5-element optical design and a wide 58° apparent field of view, these eyepieces offer a more immersive experience than traditional narrow-field planetary designs while maintaining the crisp detail needed for serious observing.

Fully multi-coated optics and internal baffling maximise light transmission and suppress stray reflections, improving contrast on subtle planetary features and fine lunar detail. The large eye lens and generous eye relief make these eyepieces comfortable to use, especially during long observing sessions or when wearing glasses.

Built with an all-metal housing and a fold-down rubber eyecup, TMB PlanetView eyepieces are robust, practical, and compatible with all standard 1.25" focusers and filters. They are also Bintel’s number one recommended first upgrade for most telescopes, offering one of the simplest and most noticeable improvements you can make to planetary and lunar performance.

The 9mm TMB PlanetView:

The TMB PlanetView 9mm Planetary Eyepiece is suited to longer focal length Schmidt-Cassegrain telescopes as well as some refractors where slightly longer focal length high magnification eyepieces are preferred.

Works particularly well with:

• • Celestron NexStar 4SE Telescope

  • Celestron NexStar 8SE Telescope

  • Celestron NexStar Evolution 8 Telescope
•  
  • Celestron NexStar Evolution 9.25 Telescope

You can connect it to M68 OAG and 2” EFW, and mount them on the M48-thread telescope side with an M54-M48 adapter.

*This adapter is packaged with the full-frame camera. So if you already have one ASI full camera then you don’t need to buy it separately.

SKU: ZWO-M54-Plate

ZWO D70-M54F Adapter may be required when fitting the ZWO OAG-L to a 36mm, 31mm /1.25" filter wheel

The ZWO ASI533MM PRO adopts a Sony back-illuminated IMX533 sensor, which is a 1-inch square frame sensor made suitable for deep sky astrophotography needs. The ZWO ASI533MM Pro can be regarded as an upgrade of the ASI183 series. Not only does it retain the high-quality features of the ASI183, such as high QE and frame rate, but it also features: no amp glow, readout noise as low as 1.0e, pixel size of 3.76 μm, 3008 x3008 array (11.31mm x 11.31mm) array and a 2-stage TEC cooling. It is highly recommended for beginners of deep sky astrophotography.

1-inch Square Frame
The IMX533 is a 1-inch square frame CMOS image sensor with approximately 9M effective pixels at a pixel size of 3.76 μm. The 14-bit digital output of IMX533 makes it possible to read out signals of 9m effective pixels at a high speed of 20 frames per second with read noise as low as 1.0e, the performance of which is on par with those of SCMOS or EMCCD sensors. This sensor is suitable for image needs that require high definition and low noise.

Full Upgrade
The ZWO ASI533MM Pro is considered a full upgrade version of the ASI183 series.

Camera Curve

Quantum Efficiency

Based on ZWO’s calculation, the peak quantum efficiency of ASI533MM Pro is greater than 91%.

Zero Amp Glow

Traditional CMOS sensors can generate weak infrared light, which is equivalent to a light source during exposures. The ASI533MM Pro uses a no-glow circuitry to ensure best quality images regardless of gain or exposure length.

2 Stage TEC Cooling
The 2-stage thermoelectric can cool the CMOS sensor to 35 degrees below the ambient temperature (based on a 30 degree ambient temperature test results). Greatly reducing dark current and thereby improving the signal to noise ratio, even with a long expose of hundreds of seconds. Note: the lower the ambient temperature is, the smaller the Delta T is.

Dark Current

USB 3.0 & 256M DDR3 Memory
ASI533MM Pro is equipped with a USB 3.0 transmission interface. In 14-bit ADC mode, the output frame rate can reach 20 frames per second. Additionally, the 256M DDR3 memory ensures a more stable data transmission during long exposure without frame loss, and can also relax the hardware requirements of the computer used for data capture.
