Next month’s meeting of the Spectroscopy Special Interest Group will be Wed, Sep 10.
At this meeting Tony Harding and I will deploy a spectroscopic atlas we’ve been working on for the past 16 months. It is titled “Low Resolution Spectral Atlas For Amateur Astronomers” and is intended to be a useful reference for anyone engaged in or starting out with low resolution spectroscopy using an SA100 or SA200 grating filter. This atlas will be in PDF format and made freely available to everyone interested.
