Details:
Together with Slovakian photographer Tomáš Slovinský (CC to him) we would like to introduce you challenging and educational mosaic of comet NEOWISE's path over Slovakian High Tratras mountains (symbolically chosen for this mosaic as they are known for highest placed astronomical observatory in central Europe, where several comets were discovered in 50' of last century). Mosaic starts from the comet's first good visibility on July 9 and ends almost a month after, showing slow metamorphosis of the comet's tails and head as it approached Sun and Earth respectively (see annotated version) for each second day. To make this mosaic, we used the same equipment and traveled every day/night for clear skies hundreds to thousands of kilometers and so we are very happy the idea was fulfilled after all struggles, eventually. It was also color corrected and calibrated to get as much as possible details of the comet every day. We hope you will like this result as well.
Mosaic shows comet from July 9th to August 3rd, so almost a month paths, with position of the comet every second day. You can also notice the Milky Way and deep sky objects on right of majestic Big Dipper asterism closer to the center. Image is result of sophisticated cooperation with great Slovakian photographer Tomáš Slovinský, who took the wonderful foreground panorama of High Tatras from Kozí Kameň mount, Slovakia (from where the path of comete perfectly projected over the High Tatras), and also lots of data of the comet when weather was not favorable for observation from the Czech Republic for me. As we were equiped with the same gear, it was easy to combine all data then and be able to finish this mosaic. For the foreground used Canon 6D modified, Sigma 50mm, f2.0, ISO 10000, 70x8s panorama from tripod with Optolong L-Pro filter. For the comet itself it was everyday shooting with 50mm (f2.2, ISO 1250, 30s exposures) or 24mm (same setting – to get whole ion tail) using Vixen Polarie mount.
