There is growing interest within the Denver Astronomical Society for a special interest group focused on photometry, spectroscopy, and scientific measurements of astronomical objects.

Photometry uses physical measurements to quantify the luminosity and flux of stars and asteroids. Spectroscopy involves capturing and analyzing optical spectra to determine chemical composition, temperature, Doppler shift, and stellar class.

Astrometry is the measurement of the positions and motions of celestial bodies, such as stars and asteroids.

This special interest group will use some of the same astronomical tools as the ASIG, such as astronomical cameras and tracking mounts, but will focus more on scientific analysis of captured imagery.

Watch your email for further developments. Interested members can also join the newly-created #ssig-general and #das-ssig-announcements Slack channels to keep informed about the latest developments.
