      Description

      EDIT: I'm always proud when one of my images is selected for IOTD, but the credit goes out to all the people, who share their data using a CC license. Without those data this wouldn't be possible. If you want to participate in future Crowd Image projects, without using a CC license, you can also drop me a PM, and then I'll add you to the list I keep of people, who have kindly given me permission to use their data. Thanks in advance!

      This is a crowd image. It was made by combining data from 132 different amateur astronomers.

      It's my first successful attempt making a crowd image mosaic. Both M81 and M82 images was used, as well as images of both galaxies.

      Version B is the same dataset, but reprocessed with the focus only on M82.

      If you want to see more examples of Crowd Images, have a look in my gallery. There are also some examples describing the method I use.

      All processing was done solely in PixInsight.
