Spectroscopy of Altair (and Vega) in Lichfield, UK 11/10/2018, using CCDSPEC, Sky Watcher Equinox Pro 80mm OTA on Manfrotto manual mount

A new star tonight for me – Altair! I have not taken a spectrum of this star before. Being also an A type star (A7V), it was going to be similar to Vega (A0V). Therefore, I took a spectrum of Vega for comparison too..

Taken using CCDSPEC spectrometer with Sky Watcher Equinox Pro 800mm Telescope on alt-az undriven Manfrotto mount – hand-guided for 50 second exposures.

RSPEC software has some great reference spectra which I was able to use to calibrate these images this evening. Cross checked using my own image of Vega as reference spectrum.

Note Vega = A0V spectral type

Altair = A7V spectral type
