Another year has passed with many meteor spectra. As in the last year (2020), here is the report of these spectra, recorded at Maienfeld during the year 2021 meteor-spectra-2021Download The spectra were recorded with a DMK 33GX249 camera from The Imaging Source (thanks to Roger Spinner for giving me this camera), equipped with a Kowa … Continue reading Meteor spectra 2021
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
