brownrb1 0 Posted July 30, 2020 Vega (1) .pdf Hi, After correcting some glitches with my Alpy-Camera I imaged a spectrum of Vega the other night and got my Masters and calibration from Alpy calibration module. I think that I will enjoy using Demetra to do data reduction. Hopefully I will be out tonight and get spectra of various stars and use Demetra to get their profiles. Attached is a screenshot of the profile of Vega. Thanks Dick Share this post Link to post Share on other sites

apricot 716 Posted July 30, 2020 Congrats for this first light Dick. Did you notice that the Balmer lines are a bit offset on the calibrated spectrum ? This is not expected on a well-calibrated Alpy spectrum. Jean-Philippe Share this post Link to post Share on other sites
