Another year has passed with many meteor spectra. As in the last year (2021), here is the report of these spectra, recorded at Maienfeld during the year 2022 Meteor spectra 2022 The spectra were recorded with a DMK 33GX249 camera from The Imaging Source (thanks to Roger Spinner for giving me this camera), equipped with … Continue reading Meteor spectra 2022

Creation and use of flat field for meteor spectroscopy
In astro photography and spectroscopy a flat field is often used to correct for variations of sensitivity over the image sensor. It is applied by dividing the original image by a suitable flat field image, thereby reducing or eliminating these sensitivity errors. The flat image is obtained with the same optics by taking a short … Continue reading Creation and use of flat field for meteor spectroscopy
New publication about meteor spectroscopy
The method of using an orthographic transformation to linearize spectra is getting used more frequently. A research group from the Beijing National Observatory of Space Environment in China has used the method for the analysis of video meteor spectra and is publishing the results now. Sipeng Yang et. al., MIOS optical subsystem for determining physical … Continue reading New publication about meteor spectroscopy
Meteor spectra 2020
Just like the year before (meteor spectra 2019 ), I put together the spectra recorded in 2020 in a list: meteor-spectra-2020Download The equipment and the processing of the spectra is the same as before, so it is not repeated here, just an example:
