2020-07-12, comet C/2020 F3 (NEOWISE) – updated

Another mostly clear night albeit with a strong wind. Before heading to to observing site, I was able to see the comet through my bedroomwindow. Upon arrival at the site I had to use the car to shield the equipment from the strong wind. The comet’s tail is becoming more and more prominent. An hour before dawn noctilucent clouds appeared again.

2020-07-11, C/2020 F3 (NEOWISE)

After days filled with rain, the skies finally cleared. Upon arrival at my observing site a big dark cloud obscured the comet but it’s bright tail gave away the location. What a sight! The night concluded with a nice display of noctilucent clouds.

2020-05-30, Crew Dragon flyby

A couple of minutes after the Internation Space Station, the Crew Dragon followed in the same orbit. Although I did not see the Crew Dragon, the camera (Canon EOS R and Sigma 135mm/F1.8 ART) recorded the flyby very low over the horizon. Individual images from this movie were stacked to show the Crew Dragon (the trail at the bottom of the image).

2020-04, comets from city center.

Tried to image a couple of comets from my parents’ backyard, a 5 minute walk from my own apartment. With over 200,000 inhabitants the light pollution in the city of Almere is huge. Naked eye limit is approximately magnitude +4, so visual observations are limited to the moon and planets. Nevertheless I was succesvol in imaging the currently visible comets: C/2017 T2 (PANSTARRS), C/2019 Y1 (ATLAS) and C/2019 Y4 (ATLAS). Equipment used was a William Optics Star 71 telescope (71mm, f=348mm) and EOS R camera mounted on a Rainbow Astro RST-135 mount. Also tried the new software for the Staraid autoguider with the new option guiding on objects like comets. For the last images I installed my good old IDAS Light Pollution Suppression filter inside the telescope.
