3.8° Prism

 

Designed for the advanced user looking for the maximum resolution, this device centralises the spectrum on the optical axis and reduces the small amount of coma sometimes visible in the red region of spectra captured with the Star Analyser 100.


It is mounted in a 1.25" filter holder for direct attachment to the Star Analyser 100 and has been AR coated on both sides.

 

Allignment markings indicate correct orientation with the Star Analyser 100. It can be mounted either behind the SA100 (adding 15mm to the distance to the camera sensor) and held in place by an optional locking ring, or ahead of it.

 

Note that with the prism in place, the wavelength scale becomes significantly non linear so a non linear wavelength calibration should be used.
