We released the new version of JUDO2 (JAXA Universe Data Oriented 2nd generation), DARTS's web-tool to display/superpose images and footprints by JAXA's satellites and other satellites and observatories. JUDO2 uses Aladin Lite to display all sky images. There are several image projection algorithms; Aladin Lite is also updated, and now 8 different projection algorithms are available. In the example right, MAXI all sky image and constellation pictures are superposed with the standard Hammer-Aitoff projection. Try different projection altorithms, and have fun to compare how they look like.
