Binocular comet Leonard - 5.12.2021 at 05.30 - 5.12.2021 at 06.15 Järvenpää Observation number 102993

Visibility II / V

I’m still trying to figure out how to get the images from the comet stacked, because at least DeepSkyStacker’s comet mode didn’t work. However, I managed to make a short comet with a data time of about 45 minutes about the comet. I first processed the images using Camera Raw, then uploaded them to Photoshop as a series of images. After that, I adjusted the aspect ratio to the right and exported it as mp4 video. The fact that you can process videos in Photoshop became a new thing for me. I’ve always thought it was just for pictures.

  • Weather
    • Kauhean kylmä oli. Noin -20 astetta. Ei tuo kylmyys kuitenkaan haitannut kuvaamista muuten kuin kuluttamalla akkuja nopeammin ja näin ollen jättäen kuvaukset lyhyeen.
