Shelyak - Support module with 1200 lines/mm grating
This is the Lhires III 1200gr/mm version and is used for fainter objects in general. It is recommended for star monitoring, but also for novae whose emission lines are too large to be recorded in a single spectra with a KAF400 based camera for example and a 2400 lines/mm grating.
Shelyak - Grating Module for Lhires III - 1200gr/mm
Shelyak Grating Modules work in conjuction with the Lhires III and are a main determining factor in the resolution of spectral lines vs the possible magnitude that can be obtained. Different grating modules can be used in different applications so it is important to choose the ideal one to generate most accurate results with whatever slit, telescope aperture, and camera sensor format is being used.
