STAR ANALYSER 200 - Optimised for the larger aperture longer focal length telescope with larger camera sensors

The STAR ANALYSER is used on the following pictures with an 80mm reflector telescope and an unmodified Philips Toucam Pro webcam, to reveal the telltale signature of molecules in the atmosphere of the magnitude +3.4 red giant Delta Virginis (spectral class M3 iii) (Graph plotted from spectrum image using Visual Spec software)

With the Star Analyser 100....                    ...turn this...                                 ...into this!

Since its launch in 2005, the Star Analyser 100 has introduced thousands of amateur astronomers worldwide to the fascinating field of spectroscopy. Over this period, the equipment used by amateurs has evolved with larger aperture telescopes, bigger camera sensors and close coupled filter wheels becoming more common. The new Star Analyser 200 model has been developed with these users in mind. Using the same Paton Hawksley high efficiency blazed diffraction grating technology as the SA100, but with double the line density. The SA200 is designed for applications where it is difficult to achieve the optimum spacing needed for the SA100. The SA200 gives the same length of spectrum at half the spacing compared with the SA100.   

For most users the SA100 is expected to continue to be the model of choice, particularly for those using cameras with small sensors, giving optimum performance for example with the SA100 mounted on the camera nosepiece.

* Professional Astronomers routinely use the power of spectroscopy to reveal the secrets of the universe. Now the STAR ANALYSER can do the same for the amateur imager at an affordable price with this simple telescope attachment.
* Used like a conventional 1.25 inch filter, it is the ideal accessory for today's low cost astronomical imaging cameras, webcams and video cameras.
* For example, with a telescope of just 80mm aperture and a simple unmodified webcam, the hidden characteristics of hundreds of stars down to magnitude +4 can be revealed. With a 200mm aperture and a sensitive long exposure CCD imager, the identification of bright Novae and Supernovae or even a measurement of the expansion of the universe from the redshift of a Quasar are possible.


To take spectra of a star via a telescope by using a dSLR or a CCD camera, you'd need this T-ring adapter:

M28 to M42 Camera T-ring Adapter for 1.25" Star Analyser

To take spectra of a star via an ordinary camera lens with you dSLR or CSC (compact system camera), you'd need this M58 adapter that screws into the front of your camera lens:

M58 Camera Lens Adapter for 1.25" Star Analyser


* High quality transmission diffraction grating mounted in a standard 1.25 inch filter cell
* Low profile (5.2mm above the thread) filter suitable for use in close coupled filter wheels

* Anti- reflection coated glass protects the grating surface
* High efficiency 200 lines/mm blazed design
* Spectrum direction marked on the filter cell
* Optimised for the larger aperture longer focal length telescope with larger camera sensors
* Star and spectrum can be recorded in the same image, which aids identification and calibration

*Can be used with  filter wheels designed for unmounted filters using the optional mounting kit.
