Tom Field of RSPEC Real Time Spectroscopy will host an online presentation on July 21 to show how to capture stellar spectra using telescopes as small as 6-inch or with DSLR cameras. The spectroscopy program will be held using Zoom and hosted by the Mid-Hudson Astronomical Association. Registration for the presentation is available here.
Field will describe the spectroscopy process which can be used with amateur equipment and without major expenses, dark skies, or a Ph.D. In astrophysics. He will explain the simple science of spectrums and show examples of amateur efforts.
During the presentation, viewers will learn that with just a small telescope you can easily:
– determine any star’s OBAFGKM star-type and temperature from its spectra curve.
– identify the composition of a star or nebula from its emission and absorption lines
– detect the cosmological red-shift of a distant quasar.
– measure the blue-shift of a supernova’s expanding shell as it races towards us at millions of miles/hour.
RSPEC Real Time Spectroscopy’s RSpec software enables you to rapidly go from a static image (FITS, JPG, etc. or DSLR) or video file to a calibrated spectrum graph – in real-time. This means you can see a star or planet’s spectrum graph instantly, right at your telescope.
The process is accomplished using RSpec’s inexpensive Star Analyzer grating (shown in Image 1) which can installed on almost any camera or telescope.
