We hope to incorporate a listing of papers written by FAAS observers -- information
about their work, techniques, results, the agonies and the extacies.
They can be submitted to
jmsivo@sivo.com, where they will be reviewed
and put on the FAAS website. (Click on the blue title to access the article.) |
Title / Author | Summary |
Amateur Astronomical Spectroscopy: Highlights of what is Currently Achievable By Dale E. Mais | The arrticle focuses on the instrument produced by Santa Barbara Instrument Group's Self-Guided Spectrometer (SGS). In the past, due to the limitations of film based detection and amateurs were limited to obtaining spectra of only the brightest stars and nebulae. The SGS allows spectra to be obtained with only modest aperture instruments of stars down to magnitudes 10-12. magnitude. |
Resolution Calculation for a Slitless Spectrograph By Dr. Doug West | This article explains how to assemble a slitless spectrograph from commercially available components and then calculate the spectral resolution of the instrument. |
A Comparative Review of some Commercial Spectrographs By Stephen J. Dearden | This article is intended to assist the newcomer to amateur astronomical spectroscopy who is contemplating the purchase of a ready-made commercial spectrometer or spectrograph. It provides some guidelines and advice with a critical review of some spectroscopic equipment that can be found on the commercial market and that may be adapted and modified for use as astronomical spectrographs. |
Design and Use of a Spectrograph at a Resolution of R=3000 By Christian Buil | This is written for a specific design criteria, but it is an excellent procedure for amateurs to go through concerning the design process for any spectrograph. The following sections are included in the article: The specifications; Choosing a grating;Choosing a diffraction angle; Determination of the focal length for the collimation lens; Determination of the focal length for the camera optic; The effective spectral resolution; The spectral range; The optical transmission; The spectrograph's sensitivity; The signal expressed in electrons; The signal to noise ratio; Building and tuning the spectrograph; The performances; Extracting the spectral profile; Spectral calibration; Frequent lines in stars' and nebulae's spectra; Radiometric calibration; and Characterization of the line profile. |
