Io and Shadow Transit 12/05/05 - Eric Walker

The late evening of Thursday 12 May 2005 was fantastic for viewing and imaging Jupiter. Within the relatively short time period of 4 hours you could see the Great Red Spot, Europa's shadow transiting the surface, Io and its shadow transiting the surface. I used my 8" SCT, Nikon Coolpix 5700 afocally attached to a 15mm Plossl. Multiple images were stacked using Registax2 and fine-tuned with Adobe Photoshop CS. The image was taken at 2315h UT (0015h BST) and shows the Great Red Spot disappearing over the western (preceding) edge, Io emerging from transit (western edge, NEB), Io shadow mid-transit (NEB), Europa to north-west. Note that south is up and west is left. www.astrophotos.plus.com
