Transit of Mercury of November 11th 2019. I had to drive some hours to manage to dodge the clouds and be able to image the transit of Mercury. The weather was very difficult, with rain showers and a lot of wind, which made imaging difficult. Eventually, I had to get the scope repacked quickly before mid-transit to avoid an incoming heavy rain shower. Among the 500 collected images, only a few were good enough to allow making sharp stack of images. Recorded with a 190mm Maksutov-Newton telescope and a DSLR (high res here).
Mosaic image of the Eclipsed Moon with Mars, the Milky way and its nebulaes. The Gegenshein is weakly visible as a glow located between Mars and the Moon. You can try to spot Helix Nebula and comet C/2018 N1 Neowise in the higher resolution image here. It was acquired with modded Sony A7S and Sigma Art 85mm f/1.4 used at f/2.8. Making this image was a real race against time to make the 15 individial frames composing the image during the 100 minutes of the duration of the totality.
