Polar Lights at Valkea Lodge, Pello, Finland, 28 February 2019 Polar lights are not related to meteors but are beautiful to view anyway. I spent a week of holidays in the Valkea Lodge in Pello, Finland, close to the swedish border and to the polar circle. As the sunspot cycle approaches the minimum, the sun … Continue reading Polar Lights near solar minimum
Meteor spectra analysed with Python
Summary This manual explains the use of a Python script for the analysis of video meteor spectra. The theory behind it has been described in (Dubs and Schlatter, 2015): meteor_spectroscopy_wgn43-4_2015.pdf). Until now, the method had been applied successfully to analyse meteor spectra obtained with high sensitive video cams such as the Watec 902 H2 ultimate … Continue reading Meteor spectra analysed with Python
M20171209 spectrum by Koji Maeda analysed
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
Schiefspiegler
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

New Publication in eMeteorNews: Slow Meteors
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
