RSpec Star Analyser Spacer, SA-SPACER
This spacer is for use with our Paton Hawksley Star Analyzer SA-100 diffraction grating which can be used to observe the spectra of astronomical objects. The Star Analyser Spacer is an empty 1.25" filter cell. use it to increase the distance from your CCD sensor to the SA-100 by an adjustable 7-10mm. The minimum recommended distance (in mm) from your CCD sensor to our Star Analyzer SA-100 grating is 4x the camera pixel size in microns. Use this spacer to fine-tune the distance.
