A few pictures taken during our #ADASS2025 tutorial on Sunday. Participants actively manipulated HiPS and MOCs on their laptops. A very good start to the ADASS XXXV meeting in Görlitz.
HiPS3D triggered a lot of interest and questions. Try it yourself : aladin.cds.unistra.fr/AladinLite/H...

Our mystery object was Saturn (and its moons) !
Can you find the other location in the VPHAS DR4 survey where Saturn was also observed ? (with a different date and location, of course)
Let us know if you find this format of mini tutorials in threads useful !

The intersection spans only a few minutes of time, on 2017-07-26, between 02:52:50 and 02:58:23.
We can use the IMCCE SkyBot tool (`Ctrl+L > IMCCE SkyBot` tab on the right), enter the median date and time and search for solar system objects around these coordinates at that time.
