  Meteor Spectrum Calibration Example Introduction Meteor spectra can give a lot of information about the meteor, such as composition and temperature. However, for amateurs the calibration of the spectra is not easy. Here a method is given for grating spectra recorded with a video camera, which produces linear spectra with constant dispersion. The method … Continue reading M20171209 spectrum by Koji Maeda analysed

The first telescope I made myself was a Schiefspiegler, an off-axis design invented by Anton Kutter The Schiefspiegler.pdf. It is an ideal telescope for planetary observations, as it has no central obstruction and gives diffraction limited images with good seeing provided. I choose an aperture of 110 mm and focal length 2200 mm, allowing to … Continue reading Schiefspiegler

OHP spectroscopy workshop Each year, Association Aude and Shelyak Instruments organize the Spectro Star Party at the Observatoire de Haute Provence, in St Michel l'Observatoire, near Manosque in southern France. http://www.shelyak.com/contenu.php?id_contenu=147&id_dossier=7 The location The equipment The video camera equipped with a 600 l/mm grating in the green box, at the side of the observation field. … Continue reading 1st meteor spectrum from OHP 2017

Posted by Martin Dubs | Jul 4, 2017 | News, Observations | 0 | by Martin Dubs, Stefano Sposetti, Roger Spinner and Beat Booz Slow meteors are studied with video observations and spectroscopy. A comparison of their orbits and spectra points to a common origin. Although they do not belong to some meteor stream, they … Continue reading New Publication in eMeteorNews: Slow Meteors

Sometimes it is useful to visualize an optical design and calculate the optical quality. A free program for doing that is BEAM4 from http://www.stellarsoftware.com/ I had used an earlier test version, but now it is available as a free version and more user friendly, so I gave it a try. I chose the Czerny spectrograph … Continue reading Test of optical ray tracing software
