The new Star Analyser 200 features the same Paton Hawksley high efficiency blazed diffraction grating technology as the SA100, but with double the line density. 

Since the Star 100 was introduced equipment used by amateurs has evolved with larger aperture telescopes, bigger camera sensors /*C*and*C*/ close coupled filter wheels becoming more common. The new Star Analyser 200 model has been developed with these users in mind.

Designed for applications /*C*where*C*/ 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.

The Star Analyser 200 Features:

• High quality transmission diffraction grating mounted in a custom low profile 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 /*C*and*C*/ spectrum can be recorded in the same image, which aids identification /*C*and*C*/ calibration

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

For most users the SA100 continues to be the model of choice, particularly for those using cameras with smaller sensors. When used with these cameras optimum performance can, for example, be achieved with the SA100 mounted on the camera nosepiece.
